This repository contains the Llama Stack API specifications as well as API Providers and Llama Stack Distributions.
The Llama Stack defines and standardizes the building blocks needed to bring generative AI applications to market. These blocks span the entire development lifecycle: from model training and fine-tuning, through product evaluation, to building and running AI agents in production. Beyond definition, we are building providers for the Llama Stack APIs. These were developing open-source versions and partnering with providers, ensuring developers can assemble AI solutions using consistent, interlocking pieces across platforms. The ultimate goal is to accelerate innovation in the AI space.

# Llama Stack Distribution
A Distribution is where APIs and Providers are assembled together to provide a consistent whole to the end application developer. You can mix-and-match providers -- some could be backed by local code and some could be remote. As a hobbyist, you can serve a small model locally, but can choose a cloud provider for a large model. Regardless, the higher level APIs your app needs to work with don't need to change at all. You can even imagine moving across the server / mobile-device boundary as well always using the same uniform set of APIs for developing Generative AI applications.

# Meta Reference Distribution
The `llamastack/distribution-meta-reference-gpu` distribution consists of the following provider configurations.
| **API** | **Inference** | **Agents** | **Memory** | **Safety** | **Telemetry** |
|----------------- |--------------- |---------------- |-------------------------------------------------- |---------------- |---------------- |
| **Provider(s)** | meta-reference | meta-reference | meta-reference, remote::pgvector, remote::chroma | meta-reference | meta-reference |
### Start the Distribution (Single Node GPU)
```
$ cd distributions/meta-reference-gpu
$ ls
build.yaml compose.yaml README.md run.yaml
$ docker compose up
```
> [!NOTE]
> This assumes you have access to GPU to start a local server with access to your GPU.
> [!NOTE]
> `~/.llama` should be the path containing downloaded weights of Llama models.
This will download and start running a pre-built docker container. Alternatively, you may use the following commands:
```
docker run -it -p 5000:5000 -v ~/.llama:/root/.llama -v ./run.yaml:/root/my-run.yaml --gpus=all distribution-meta-reference-gpu --yaml_config /root/my-run.yaml
```
### Alternative (Build and start distribution locally via conda)
- You may checkout the [Getting Started](../../docs/getting_started.md) for more details on building locally via conda and starting up a meta-reference distribution.
### Start Distribution With pgvector/chromadb Memory Provider
##### pgvector
1. Start running the pgvector server:
```
docker run --network host --name mypostgres -it -p 5432:5432 -e POSTGRES_PASSWORD=mysecretpassword -e POSTGRES_USER=postgres -e POSTGRES_DB=postgres pgvector/pgvector:pg16
```
2. Edit the `run.yaml` file to point to the pgvector server.
```
memory:
- provider_id: pgvector
provider_type: remote::pgvector
config:
host: 127.0.0.1
port: 5432
db: postgres
user: postgres
password: mysecretpassword
```
> [!NOTE]
> If you get a `RuntimeError: Vector extension is not installed.`. You will need to run `CREATE EXTENSION IF NOT EXISTS vector;` to include the vector extension. E.g.
```
docker exec -it mypostgres ./bin/psql -U postgres
postgres=# CREATE EXTENSION IF NOT EXISTS vector;
postgres=# SELECT extname from pg_extension;
extname
```
3. Run `docker compose up` with the updated `run.yaml` file.
##### chromadb
1. Start running chromadb server
```
docker run -it --network host --name chromadb -p 6000:6000 -v ./chroma_vdb:/chroma/chroma -e IS_PERSISTENT=TRUE chromadb/chroma:latest
```
2. Edit the `run.yaml` file to point to the chromadb server.
```
memory:
- provider_id: remote::chromadb
provider_type: remote::chromadb
config:
host: localhost
port: 6000
```
3. Run `docker compose up` with the updated `run.yaml` file.
### Serving a new model
You may change the `config.model` in `run.yaml` to update the model currently being served by the distribution. Make sure you have the model checkpoint downloaded in your `~/.llama`.
```
inference:
- provider_id: meta0
provider_type: meta-reference
config:
model: Llama3.2-11B-Vision-Instruct
quantization: null
torch_seed: null
max_seq_len: 4096
max_batch_size: 1
```
Run `llama model list` to see the available models to download, and `llama model download` to download the checkpoints.

# Meta Reference Quantized Distribution
The `llamastack/distribution-meta-reference-quantized-gpu` distribution consists of the following provider configurations.
| **API** | **Inference** | **Agents** | **Memory** | **Safety** | **Telemetry** |
|----------------- |------------------------ |---------------- |-------------------------------------------------- |---------------- |---------------- |
| **Provider(s)** | meta-reference-quantized | meta-reference | meta-reference, remote::pgvector, remote::chroma | meta-reference | meta-reference |
The only difference vs. the `meta-reference-gpu` distribution is that it has support for more efficient inference -- with fp8, int4 quantization, etc.
### Start the Distribution (Single Node GPU)
> [!NOTE]
> This assumes you have access to GPU to start a local server with access to your GPU.
> [!NOTE]
> `~/.llama` should be the path containing downloaded weights of Llama models.
To download and start running a pre-built docker container, you may use the following commands:
```
docker run -it -p 5000:5000 -v ~/.llama:/root/.llama \
-v ./run.yaml:/root/my-run.yaml \
--gpus=all \
distribution-meta-reference-quantized-gpu \
--yaml_config /root/my-run.yaml
```
### Alternative (Build and start distribution locally via conda)

# Building a Llama Stack Distribution
This guide will walk you through the steps to get started with building a Llama Stack distributiom from scratch with your choice of API providers. Please see the [Getting Started Guide](./getting_started.md) if you just want the basic steps to start a Llama Stack distribution.
## Step 1. Build
In the following steps, imagine we'll be working with a `Meta-Llama3.1-8B-Instruct` model. We will name our build `8b-instruct` to help us remember the config. We will start build our distribution (in the form of a Conda environment, or Docker image). In this step, we will specify:
- `name`: the name for our distribution (e.g. `8b-instruct`)
- `image_type`: our build image type (`conda | docker`)
- `distribution_spec`: our distribution specs for specifying API providers
- `description`: a short description of the configurations for the distribution
- `providers`: specifies the underlying implementation for serving each API endpoint
- `image_type`: `conda` | `docker` to specify whether to build the distribution in the form of Docker image or Conda environment.
At the end of build command, we will generate `<name>-build.yaml` file storing the build configurations.
After this step is complete, a file named `<name>-build.yaml` will be generated and saved at the output file path specified at the end of the command.
#### Building from scratch
- For a new user, we could start off with running `llama stack build` which will allow you to a interactively enter wizard where you will be prompted to enter build configurations.
```
llama stack build
```
Running the command above will allow you to fill in the configuration to build your Llama Stack distribution, you will see the following outputs.
```
> Enter an unique name for identifying your Llama Stack build distribution (e.g. my-local-stack): 8b-instruct
> Enter the image type you want your distribution to be built with (docker or conda): conda
Llama Stack is composed of several APIs working together. Let's configure the providers (implementations) you want to use for these APIs.
> Enter the API provider for the inference API: (default=meta-reference): meta-reference
> Enter the API provider for the safety API: (default=meta-reference): meta-reference
> Enter the API provider for the agents API: (default=meta-reference): meta-reference
> Enter the API provider for the memory API: (default=meta-reference): meta-reference
> Enter the API provider for the telemetry API: (default=meta-reference): meta-reference
> (Optional) Enter a short description for your Llama Stack distribution:
Build spec configuration saved at ~/.conda/envs/llamastack-my-local-llama-stack/8b-instruct-build.yaml
```
**Ollama (optional)**
If you plan to use Ollama for inference, you'll need to install the server [via these instructions](https://ollama.com/download).
#### Building from templates
- To build from alternative API providers, we provide distribution templates for users to get started building a distribution backed by different providers.
The following command will allow you to see the available templates and their corresponding providers.
```
llama stack build --list-templates
```
![alt text](resources/list-templates.png)
You may then pick a template to build your distribution with providers fitted to your liking.
```
llama stack build --template tgi
```
```
$ llama stack build --template tgi
...
...
Build spec configuration saved at ~/.conda/envs/llamastack-tgi/tgi-build.yaml
You may now run `llama stack configure tgi` or `llama stack configure ~/.conda/envs/llamastack-tgi/tgi-build.yaml`
```
#### Building from config file
- In addition to templates, you may customize the build to your liking through editing config files and build from config files with the following command.
- The config file will be of contents like the ones in `llama_stack/distributions/templates/`.
```
$ cat llama_stack/templates/ollama/build.yaml
name: ollama
distribution_spec:
description: Like local, but use ollama for running LLM inference
providers:
inference: remote::ollama
memory: meta-reference
safety: meta-reference
agents: meta-reference
telemetry: meta-reference
image_type: conda
```
```
llama stack build --config llama_stack/templates/ollama/build.yaml
```
#### How to build distribution with Docker image
> [!TIP]
> Podman is supported as an alternative to Docker. Set `DOCKER_BINARY` to `podman` in your environment to use Podman.
To build a docker image, you may start off from a template and use the `--image-type docker` flag to specify `docker` as the build image type.
```
llama stack build --template local --image-type docker
```
Alternatively, you may use a config file and set `image_type` to `docker` in our `<name>-build.yaml` file, and run `llama stack build <name>-build.yaml`. The `<name>-build.yaml` will be of contents like:
```
name: local-docker-example
distribution_spec:
description: Use code from `llama_stack` itself to serve all llama stack APIs
docker_image: null
providers:
inference: meta-reference
memory: meta-reference-faiss
safety: meta-reference
agentic_system: meta-reference
telemetry: console
image_type: docker
```
The following command allows you to build a Docker image with the name `<name>`
```
llama stack build --config <name>-build.yaml
Dockerfile created successfully in /tmp/tmp.I0ifS2c46A/DockerfileFROM python:3.10-slim
WORKDIR /app
...
...
You can run it with: podman run -p 8000:8000 llamastack-docker-local
Build spec configuration saved at ~/.llama/distributions/docker/docker-local-build.yaml
```
## Step 2. Configure
After our distribution is built (either in form of docker or conda environment), we will run the following command to
```
llama stack configure [ <docker-image-name> | <path/to/name.build.yaml>]
```
- For `conda` environments: <path/to/name.build.yaml> would be the generated build spec saved from Step 1.
- For `docker` images downloaded from Dockerhub, you could also use <docker-image-name> as the argument.
- Run `docker images` to check list of available images on your machine.
```
$ llama stack configure tgi
Configuring API: inference (meta-reference)
Enter value for model (existing: Meta-Llama3.1-8B-Instruct) (required):

Do you want to configure llama_guard_shield? (y/n): y
Entering sub-configuration for llama_guard_shield:
Enter value for model (default: Llama-Guard-3-1B) (required):
Enter value for excluded_categories (default: []) (required):
Enter value for disable_input_check (default: False) (required):
Enter value for disable_output_check (default: False) (required):
Do you want to configure prompt_guard_shield? (y/n): y
Entering sub-configuration for prompt_guard_shield:
Enter value for model (default: Prompt-Guard-86M) (required):

Enter value for brave_search_api_key (optional):
Enter value for bing_search_api_key (optional):
Enter value for wolfram_api_key (optional):
Configuring API: telemetry (console)
YAML configuration has been written to ~/.llama/builds/conda/tgi-run.yaml
```
After this step is successful, you should be able to find a run configuration spec in `~/.llama/builds/conda/tgi-run.yaml` with the following contents. You may edit this file to change the settings.
As you can see, we did basic configuration above and configured:
- inference to run on model `Meta-Llama3.1-8B-Instruct` (obtained from `llama model list`)
- Llama Guard safety shield with model `Llama-Guard-3-1B`
- Prompt Guard safety shield with model `Prompt-Guard-86M`
For how these configurations are stored as yaml, checkout the file printed at the end of the configuration.
Note that all configurations as well as models are stored in `~/.llama`
## Step 3. Run
Now, let's start the Llama Stack Distribution Server. You will need the YAML configuration file which was written out at the end by the `llama stack configure` step.
```
llama stack run 8b-instruct
```
You should see the Llama Stack server start and print the APIs that it is supporting
```
$ llama stack run 8b-instruct

This server is running a Llama model locally.
## Step 4. Test with Client
Once the server is setup, we can test it with a client to see the example outputs.
```
cd /path/to/llama-stack
conda activate <env> # any environment containing the llama-stack pip package will work
python -m llama_stack.apis.inference.client localhost 5000
```
This will run the chat completion client and query the distributions /inference/chat_completion API.
Here is an example output:
```
User>hello world, write me a 2 sentence poem about the moon
Assistant> Here's a 2-sentence poem about the moon:
The moon glows softly in the midnight sky,
A beacon of wonder, as it passes by.
```
Similarly you can test safety (if you configured llama-guard and/or prompt-guard shields) by:
```
python -m llama_stack.apis.safety.client localhost 5000
```
Check out our client SDKs for connecting to Llama Stack server in your preferred language, you can choose from [python](https://github.com/meta-llama/llama-stack-client-python), [node](https://github.com/meta-llama/llama-stack-client-node), [swift](https://github.com/meta-llama/llama-stack-client-swift), and [kotlin](https://github.com/meta-llama/llama-stack-client-kotlin) programming languages to quickly build your applications.
You can find more example scripts with client SDKs to talk with the Llama Stack server in our [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main/examples) repo.

# Llama CLI Reference
The `llama` CLI tool helps you setup and use the Llama Stack & agentic systems. It should be available on your path after installing the `llama-stack` package.
### Subcommands
1. `download`: `llama` cli tools supports downloading the model from Meta or Hugging Face.
2. `model`: Lists available models and their properties.
3. `stack`: Allows you to build and run a Llama Stack server. You can read more about this [here](cli_reference.md#step-3-building-and-configuring-llama-stack-distributions).
### Sample Usage
```
llama --help
```
<pre style="font-family: monospace;">
usage: llama [-h] {download,model,stack} ...
Welcome to the Llama CLI
options:
-h, --help show this help message and exit
subcommands:
{download,model,stack}
</pre>
## Step 1. Get the models
You first need to have models downloaded locally.
To download any model you need the **Model Descriptor**.
This can be obtained by running the command
```
llama model list
```
You should see a table like this:
<pre style="font-family: monospace;">

</pre>
To download models, you can use the llama download command.
#### Downloading from [Meta](https://llama.meta.com/llama-downloads/)
Here is an example download command to get the 3B-Instruct/11B-Vision-Instruct model. You will need META_URL which can be obtained from [here](https://llama.meta.com/docs/getting_the_models/meta/)
Download the required checkpoints using the following commands:
```bash
# download the 8B model, this can be run on a single GPU
llama download --source meta --model-id Llama3.2-3B-Instruct --meta-url META_URL
# you can also get the 70B model, this will require 8 GPUs however
llama download --source meta --model-id Llama3.2-11B-Vision-Instruct --meta-url META_URL
# llama-agents have safety enabled by default. For this, you will need
# safety models -- Llama-Guard and Prompt-Guard
llama download --source meta --model-id Prompt-Guard-86M --meta-url META_URL
llama download --source meta --model-id Llama-Guard-3-1B --meta-url META_URL
```
#### Downloading from [Hugging Face](https://huggingface.co/meta-llama)
Essentially, the same commands above work, just replace `--source meta` with `--source huggingface`.
```bash
llama download --source huggingface --model-id Llama3.1-8B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama3.1-70B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama-Guard-3-1B --ignore-patterns *original*
llama download --source huggingface --model-id Prompt-Guard-86M --ignore-patterns *original*
```
**Important:** Set your environment variable `HF_TOKEN` or pass in `--hf-token` to the command to validate your access. You can find your token at [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens).
> **Tip:** Default for `llama download` is to run with `--ignore-patterns *.safetensors` since we use the `.pth` files in the `original` folder. For Llama Guard and Prompt Guard, however, we need safetensors. Hence, please run with `--ignore-patterns original` so that safetensors are downloaded and `.pth` files are ignored.
#### Downloading via Ollama
If you're already using ollama, we also have a supported Llama Stack distribution `local-ollama` and you can continue to use ollama for managing model downloads.
```
ollama pull llama3.1:8b-instruct-fp16
ollama pull llama3.1:70b-instruct-fp16
```
> [!NOTE]
> Only the above two models are currently supported by Ollama.
## Step 2: Understand the models
The `llama model` command helps you explore the models interface.
### 2.1 Subcommands
1. `download`: Download the model from different sources. (meta, huggingface)
2. `list`: Lists all the models available for download with hardware requirements to deploy the models.
3. `prompt-format`: Show llama model message formats.
4. `describe`: Describes all the properties of the model.
### 2.2 Sample Usage
`llama model <subcommand> <options>`
```
llama model --help
```
<pre style="font-family: monospace;">
usage: llama model [-h] {download,list,prompt-format,describe} ...
Work with llama models
options:
-h, --help show this help message and exit
model_subcommands:
{download,list,prompt-format,describe}
</pre>
You can use the describe command to know more about a model:
```
llama model describe -m Llama3.2-3B-Instruct
```
### 2.3 Describe
<pre style="font-family: monospace;">
+-----------------------------+----------------------------------+
| Model | Llama3.2-3B-Instruct |
+-----------------------------+----------------------------------+
| Hugging Face ID | meta-llama/Llama-3.2-3B-Instruct |
+-----------------------------+----------------------------------+
| Description | Llama 3.2 3b instruct model |
+-----------------------------+----------------------------------+
| Context Length | 128K tokens |
+-----------------------------+----------------------------------+
| Weights format | bf16 |
+-----------------------------+----------------------------------+
| Model params.json | { |
| | "dim": 3072, |
| | "n_layers": 28, |
| | "n_heads": 24, |
| | "n_kv_heads": 8, |
| | "vocab_size": 128256, |
| | "ffn_dim_multiplier": 1.0, |
| | "multiple_of": 256, |
| | "norm_eps": 1e-05, |
| | "rope_theta": 500000.0, |
| | "use_scaled_rope": true |
| | } |
+-----------------------------+----------------------------------+
| Recommended sampling params | { |
| | "strategy": "top_p", |
| | "temperature": 1.0, |
| | "top_p": 0.9, |
| | "top_k": 0 |
| | } |
+-----------------------------+----------------------------------+
</pre>
### 2.4 Prompt Format
You can even run `llama model prompt-format` see all of the templates and their tokens:
```
llama model prompt-format -m Llama3.2-3B-Instruct
```
![alt text](resources/prompt-format.png)
You will be shown a Markdown formatted description of the model interface and how prompts / messages are formatted for various scenarios.
**NOTE**: Outputs in terminal are color printed to show special tokens.
## Step 3: Building, and Configuring Llama Stack Distributions
- Please see our [Getting Started](getting_started.md) guide for more details on how to build and start a Llama Stack distribution.
### Step 3.1 Build
In the following steps, imagine we'll be working with a `Llama3.1-8B-Instruct` model. We will name our build `tgi` to help us remember the config. We will start build our distribution (in the form of a Conda environment, or Docker image). In this step, we will specify:
- `name`: the name for our distribution (e.g. `tgi`)
- `image_type`: our build image type (`conda | docker`)
- `distribution_spec`: our distribution specs for specifying API providers
- `description`: a short description of the configurations for the distribution
- `providers`: specifies the underlying implementation for serving each API endpoint
- `image_type`: `conda` | `docker` to specify whether to build the distribution in the form of Docker image or Conda environment.
At the end of build command, we will generate `<name>-build.yaml` file storing the build configurations.
After this step is complete, a file named `<name>-build.yaml` will be generated and saved at the output file path specified at the end of the command.
#### Building from scratch
- For a new user, we could start off with running `llama stack build` which will allow you to a interactively enter wizard where you will be prompted to enter build configurations.
```
llama stack build
```
Running the command above will allow you to fill in the configuration to build your Llama Stack distribution, you will see the following outputs.
```
> Enter an unique name for identifying your Llama Stack build distribution (e.g. my-local-stack): my-local-llama-stack
> Enter the image type you want your distribution to be built with (docker or conda): conda
Llama Stack is composed of several APIs working together. Let's configure the providers (implementations) you want to use for these APIs.
> Enter the API provider for the inference API: (default=meta-reference): meta-reference
> Enter the API provider for the safety API: (default=meta-reference): meta-reference
> Enter the API provider for the agents API: (default=meta-reference): meta-reference
> Enter the API provider for the memory API: (default=meta-reference): meta-reference
> Enter the API provider for the telemetry API: (default=meta-reference): meta-reference
> (Optional) Enter a short description for your Llama Stack distribution:
Build spec configuration saved at ~/.conda/envs/llamastack-my-local-llama-stack/my-local-llama-stack-build.yaml
```
#### Building from templates
- To build from alternative API providers, we provide distribution templates for users to get started building a distribution backed by different providers.
The following command will allow you to see the available templates and their corresponding providers.
```
llama stack build --list-templates
```
![alt text](resources/list-templates.png)
You may then pick a template to build your distribution with providers fitted to your liking.
```
llama stack build --template tgi --image-type conda
```
```
$ llama stack build --template tgi --image-type conda
...
...
Build spec configuration saved at ~/.conda/envs/llamastack-tgi/tgi-build.yaml
You may now run `llama stack configure tgi` or `llama stack configure ~/.conda/envs/llamastack-tgi/tgi-build.yaml`
```
#### Building from config file
- In addition to templates, you may customize the build to your liking through editing config files and build from config files with the following command.
- The config file will be of contents like the ones in `llama_stack/templates/`.
```
$ cat build.yaml
name: ollama
distribution_spec:
description: Like local, but use ollama for running LLM inference
providers:
inference: remote::ollama
memory: meta-reference
safety: meta-reference
agents: meta-reference
telemetry: meta-reference
image_type: conda
```
```
llama stack build --config build.yaml
```
#### How to build distribution with Docker image
To build a docker image, you may start off from a template and use the `--image-type docker` flag to specify `docker` as the build image type.
```
llama stack build --template tgi --image-type docker
```
Alternatively, you may use a config file and set `image_type` to `docker` in our `<name>-build.yaml` file, and run `llama stack build <name>-build.yaml`. The `<name>-build.yaml` will be of contents like:
```
name: local-docker-example
distribution_spec:
description: Use code from `llama_stack` itself to serve all llama stack APIs
docker_image: null
providers:
inference: meta-reference
memory: meta-reference-faiss
safety: meta-reference
agentic_system: meta-reference
telemetry: console
image_type: docker
```
The following command allows you to build a Docker image with the name `<name>`
```
llama stack build --config <name>-build.yaml
Dockerfile created successfully in /tmp/tmp.I0ifS2c46A/DockerfileFROM python:3.10-slim
WORKDIR /app
...
...
You can run it with: podman run -p 8000:8000 llamastack-docker-local
Build spec configuration saved at ~/.llama/distributions/docker/docker-local-build.yaml
```
### Step 3.2 Configure
After our distribution is built (either in form of docker or conda environment), we will run the following command to
```
llama stack configure [ <docker-image-name> | <path/to/name-build.yaml>]
```
- For `conda` environments: <path/to/name.build.yaml> would be the generated build spec saved from Step 1.
- For `docker` images downloaded from Dockerhub, you could also use <docker-image-name> as the argument.
- Run `docker images` to check list of available images on your machine.
```
$ llama stack configure ~/.llama/distributions/conda/tgi-build.yaml
Configuring API: inference (meta-reference)
Enter value for model (existing: Llama3.1-8B-Instruct) (required):
Enter value for quantization (optional):
Enter value for torch_seed (optional):
Enter value for max_seq_len (existing: 4096) (required):
Enter value for max_batch_size (existing: 1) (required):
Configuring API: memory (meta-reference-faiss)
Configuring API: safety (meta-reference)
Do you want to configure llama_guard_shield? (y/n): y
Entering sub-configuration for llama_guard_shield:
Enter value for model (default: Llama-Guard-3-1B) (required):
Enter value for excluded_categories (default: []) (required):
Enter value for disable_input_check (default: False) (required):
Enter value for disable_output_check (default: False) (required):
Do you want to configure prompt_guard_shield? (y/n): y
Entering sub-configuration for prompt_guard_shield:
Enter value for model (default: Prompt-Guard-86M) (required):
Configuring API: agentic_system (meta-reference)
Enter value for brave_search_api_key (optional):
Enter value for bing_search_api_key (optional):
Enter value for wolfram_api_key (optional):
Configuring API: telemetry (console)
YAML configuration has been written to ~/.llama/builds/conda/8b-instruct-run.yaml
```
After this step is successful, you should be able to find a run configuration spec in `~/.llama/builds/conda/8b-instruct-run.yaml` with the following contents. You may edit this file to change the settings.
As you can see, we did basic configuration above and configured:
- inference to run on model `Llama3.1-8B-Instruct` (obtained from `llama model list`)
- Llama Guard safety shield with model `Llama-Guard-3-1B`
- Prompt Guard safety shield with model `Prompt-Guard-86M`
For how these configurations are stored as yaml, checkout the file printed at the end of the configuration.
Note that all configurations as well as models are stored in `~/.llama`
### Step 3.3 Run
Now, let's start the Llama Stack Distribution Server. You will need the YAML configuration file which was written out at the end by the `llama stack configure` step.
```
llama stack run ~/.llama/builds/conda/tgi-run.yaml
```
You should see the Llama Stack server start and print the APIs that it is supporting
```
$ llama stack run ~/.llama/builds/local/conda/tgi-run.yaml

This server is running a Llama model locally.
### Step 3.4 Test with Client
Once the server is setup, we can test it with a client to see the example outputs.
```
cd /path/to/llama-stack
conda activate <env> # any environment containing the llama-stack pip package will work
python -m llama_stack.apis.inference.client localhost 5000
```
This will run the chat completion client and query the distributions /inference/chat_completion API.
Here is an example output:
```
User>hello world, write me a 2 sentence poem about the moon
Assistant> Here's a 2-sentence poem about the moon:
The moon glows softly in the midnight sky,
A beacon of wonder, as it passes by.
```
Similarly you can test safety (if you configured llama-guard and/or prompt-guard shields) by:
```
python -m llama_stack.apis.safety.client localhost 5000
```
You can find more example scripts with client SDKs to talk with the Llama Stack server in our [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main/examples) repo.

# Getting Started with Llama Stack
This guide will walk you though the steps to get started on end-to-end flow for LlamaStack. This guide mainly focuses on getting started with building a LlamaStack distribution, and starting up a LlamaStack server. Please see our [documentations](../README.md) on what you can do with Llama Stack, and [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main) on examples apps built with Llama Stack.
## Installation
The `llama` CLI tool helps you setup and use the Llama toolchain & agentic systems. It should be available on your path after installing the `llama-stack` package.
You have two ways to install this repository:
1. **Install as a package**:
You can install the repository directly from [PyPI](https://pypi.org/project/llama-stack/) by running the following command:
```bash
pip install llama-stack
```
2. **Install from source**:
If you prefer to install from the source code, follow these steps:
```bash
mkdir -p ~/local
cd ~/local
git clone git@github.com:meta-llama/llama-stack.git
conda create -n stack python=3.10
conda activate stack
cd llama-stack
$CONDA_PREFIX/bin/pip install -e .
```
For what you can do with the Llama CLI, please refer to [CLI Reference](./cli_reference.md).
## Starting Up Llama Stack Server
You have two ways to start up Llama stack server:
1. **Starting up server via docker**:
We provide pre-built Docker image of Llama Stack distribution, which can be found in the following links in the [distributions](../distributions/) folder.
> [!NOTE]
> For GPU inference, you need to set these environment variables for specifying local directory containing your model checkpoints, and enable GPU inference to start running docker container.
```
export LLAMA_CHECKPOINT_DIR=~/.llama
```
> [!NOTE]
> `~/.llama` should be the path containing downloaded weights of Llama models.
To download llama models, use
```
llama download --model-id Llama3.1-8B-Instruct
```
To download and start running a pre-built docker container, you may use the following commands:
```
cd llama-stack/distributions/meta-reference-gpu
docker run -it -p 5000:5000 -v ~/.llama:/root/.llama -v ./run.yaml:/root/my-run.yaml --gpus=all distribution-meta-reference-gpu --yaml_config /root/my-run.yaml
```
> [!TIP]
> Pro Tip: We may use `docker compose up` for starting up a distribution with remote providers (e.g. TGI) using [llamastack-local-cpu](https://hub.docker.com/repository/docker/llamastack/llamastack-local-cpu/general). You can checkout [these scripts](../distributions/) to help you get started.
2. **Build->Configure->Run Llama Stack server via conda**:
You may also build a LlamaStack distribution from scratch, configure it, and start running the distribution. This is useful for developing on LlamaStack.
**`llama stack build`**
- You'll be prompted to enter build information interactively.
```
llama stack build
> Enter an unique name for identifying your Llama Stack build distribution (e.g. my-local-stack): my-local-stack
> Enter the image type you want your distribution to be built with (docker or conda): conda
Llama Stack is composed of several APIs working together. Let's configure the providers (implementations) you want to use for these APIs.
> Enter the API provider for the inference API: (default=meta-reference): meta-reference
> Enter the API provider for the safety API: (default=meta-reference): meta-reference
> Enter the API provider for the agents API: (default=meta-reference): meta-reference
> Enter the API provider for the memory API: (default=meta-reference): meta-reference
> Enter the API provider for the telemetry API: (default=meta-reference): meta-reference
> (Optional) Enter a short description for your Llama Stack distribution:
Build spec configuration saved at ~/.conda/envs/llamastack-my-local-stack/my-local-stack-build.yaml
You can now run `llama stack configure my-local-stack`
```
**`llama stack configure`**
- Run `llama stack configure <name>` with the name you have previously defined in `build` step.
```
llama stack configure <name>
```
- You will be prompted to enter configurations for your Llama Stack
```
$ llama stack configure my-local-stack

```
## Testing with client
Once the server is setup, we can test it with a client to see the example outputs.
```
cd /path/to/llama-stack
conda activate <env> # any environment containing the llama-stack pip package will work
python -m llama_stack.apis.inference.client localhost 5000
```
This will run the chat completion client and query the distributions `/inference/chat_completion` API.
Here is an example output:
```
User>hello world, write me a 2 sentence poem about the moon
Assistant> Here's a 2-sentence poem about the moon:
The moon glows softly in the midnight sky,
A beacon of wonder, as it passes by.
```
You may also send a POST request to the server:
```
curl http://localhost:5000/inference/chat_completion \
-H "Content-Type: application/json" \
-d '{
"model": "Llama3.1-8B-Instruct",
"messages": [
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Write me a 2 sentence poem about the moon"}
],
"sampling_params": {"temperature": 0.7, "seed": 42, "max_tokens": 512}
}'
Output:
{'completion_message': {'role': 'assistant',
'content': 'The moon glows softly in the midnight sky, \nA beacon of wonder, as it catches the eye.',
'stop_reason': 'out_of_tokens',
'tool_calls': []},
'logprobs': null}
```
Similarly you can test safety (if you configured llama-guard and/or prompt-guard shields) by:
```
python -m llama_stack.apis.safety.client localhost 5000
```
Check out our client SDKs for connecting to Llama Stack server in your preferred language, you can choose from [python](https://github.com/meta-llama/llama-stack-client-python), [node](https://github.com/meta-llama/llama-stack-client-node), [swift](https://github.com/meta-llama/llama-stack-client-swift), and [kotlin](https://github.com/meta-llama/llama-stack-client-kotlin) programming languages to quickly build your applications.
You can find more example scripts with client SDKs to talk with the Llama Stack server in our [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main/examples) repo.

# API Providers
A Provider is what makes the API real -- they provide the actual implementation backing the API.
As an example, for Inference, we could have the implementation be backed by open source libraries like `[ torch | vLLM | TensorRT ]` as possible options.
A provider can also be just a pointer to a remote REST service -- for example, cloud providers or dedicated inference providers could serve these APIs.

# Memory API Providers
This guide gives you references to switch between different memory API providers.
##### pgvector
1. Start running the pgvector server:
```
$ docker run --network host --name mypostgres -it -p 5432:5432 -e POSTGRES_PASSWORD=mysecretpassword -e POSTGRES_USER=postgres -e POSTGRES_DB=postgres pgvector/pgvector:pg16
```
2. Edit the `run.yaml` file to point to the pgvector server.
```
memory:
- provider_id: pgvector
provider_type: remote::pgvector
config:
host: 127.0.0.1
port: 5432
db: postgres
user: postgres
password: mysecretpassword
```
> [!NOTE]
> If you get a `RuntimeError: Vector extension is not installed.`. You will need to run `CREATE EXTENSION IF NOT EXISTS vector;` to include the vector extension. E.g.
```
docker exec -it mypostgres ./bin/psql -U postgres
postgres=# CREATE EXTENSION IF NOT EXISTS vector;
postgres=# SELECT extname from pg_extension;
extname
```
3. Run `docker compose up` with the updated `run.yaml` file.
##### chromadb
1. Start running chromadb server
```
docker run -it --network host --name chromadb -p 6000:6000 -v ./chroma_vdb:/chroma/chroma -e IS_PERSISTENT=TRUE chromadb/chroma:latest
```
2. Edit the `run.yaml` file to point to the chromadb server.
```
memory:
- provider_id: remote::chromadb
provider_type: remote::chromadb
config:
host: localhost
port: 6000
```
3. Run `docker compose up` with the updated `run.yaml` file.

@ -6,10 +6,10 @@ This guide contains references to walk you through adding a new API provider.
1. First, decide which API your provider falls into (e.g. Inference, Safety, Agents, Memory).
2. Decide whether your provider is a remote provider, or inline implmentation. A remote provider is a provider that makes a remote request to an service. An inline provider is a provider where implementation is executed locally. Checkout the examples, and follow the structure to add your own API provider. Please find the following code pointers:
- [Inference Remote Adapter](../llama_stack/providers/adapters/inference/)
- [Inference Inline Provider](../llama_stack/providers/impls/)
- [Remote Adapters](https://github.com/meta-llama/llama-stack/tree/main/llama_stack/providers/remote)
- [Inline Providers](https://github.com/meta-llama/llama-stack/tree/main/llama_stack/providers/inline)

# Llama CLI Reference
The `llama` CLI tool helps you setup and use the Llama Stack & agentic systems. It should be available on your path after installing the `llama-stack` package.
## Subcommands
1. `download`: `llama` cli tools supports downloading the model from Meta or Hugging Face.
2. `model`: Lists available models and their properties.
3. `stack`: Allows you to build and run a Llama Stack server. You can read more about this in Step 3 below.
## Sample Usage
```
llama --help
```
<pre style="font-family: monospace;">
usage: llama [-h] {download,model,stack} ...
Welcome to the Llama CLI
options:
-h, --help show this help message and exit
subcommands:
{download,model,stack}
</pre>
## Step 1. Get the models
You first need to have models downloaded locally.
To download any model you need the **Model Descriptor**.
This can be obtained by running the command
```
llama model list
```
You should see a table like this:
<pre style="font-family: monospace;">

</pre>
To download models, you can use the llama download command.
### Downloading from [Meta](https://llama.meta.com/llama-downloads/)
Here is an example download command to get the 3B-Instruct/11B-Vision-Instruct model. You will need META_URL which can be obtained from [here](https://llama.meta.com/docs/getting_the_models/meta/)
Download the required checkpoints using the following commands:
```bash
# download the 8B model, this can be run on a single GPU
llama download --source meta --model-id Llama3.2-3B-Instruct --meta-url META_URL
# you can also get the 70B model, this will require 8 GPUs however
llama download --source meta --model-id Llama3.2-11B-Vision-Instruct --meta-url META_URL
# llama-agents have safety enabled by default. For this, you will need
# safety models -- Llama-Guard and Prompt-Guard
llama download --source meta --model-id Prompt-Guard-86M --meta-url META_URL
llama download --source meta --model-id Llama-Guard-3-1B --meta-url META_URL
```
### Downloading from [Hugging Face](https://huggingface.co/meta-llama)
Essentially, the same commands above work, just replace `--source meta` with `--source huggingface`.
```bash
llama download --source huggingface --model-id Llama3.1-8B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama3.1-70B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama-Guard-3-1B --ignore-patterns *original*
llama download --source huggingface --model-id Prompt-Guard-86M --ignore-patterns *original*
```
**Important:** Set your environment variable `HF_TOKEN` or pass in `--hf-token` to the command to validate your access. You can find your token at [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens).
> **Tip:** Default for `llama download` is to run with `--ignore-patterns *.safetensors` since we use the `.pth` files in the `original` folder. For Llama Guard and Prompt Guard, however, we need safetensors. Hence, please run with `--ignore-patterns original` so that safetensors are downloaded and `.pth` files are ignored.
### Downloading via Ollama
If you're already using ollama, we also have a supported Llama Stack distribution `local-ollama` and you can continue to use ollama for managing model downloads.
```
ollama pull llama3.1:8b-instruct-fp16
ollama pull llama3.1:70b-instruct-fp16
```
> [!NOTE]
> Only the above two models are currently supported by Ollama.
## Step 2: Understand the models
The `llama model` command helps you explore the models interface.
### 2.1 Subcommands
1. `download`: Download the model from different sources. (meta, huggingface)
2. `list`: Lists all the models available for download with hardware requirements to deploy the models.
3. `prompt-format`: Show llama model message formats.
4. `describe`: Describes all the properties of the model.
### 2.2 Sample Usage
`llama model <subcommand> <options>`
```
llama model --help
```
<pre style="font-family: monospace;">
usage: llama model [-h] {download,list,prompt-format,describe} ...
Work with llama models
options:
-h, --help show this help message and exit
model_subcommands:
{download,list,prompt-format,describe}
</pre>
You can use the describe command to know more about a model:
```
llama model describe -m Llama3.2-3B-Instruct
```
### 2.3 Describe

+-----------------------------+----------------------------------+
</pre>
### 2.4 Prompt Format
You can even run `llama model prompt-format` see all of the templates and their tokens:
```
llama model prompt-format -m Llama3.2-3B-Instruct
```
![alt text](https://github.com/meta-llama/llama-stack/docs/resources/prompt-format.png)
You will be shown a Markdown formatted description of the model interface and how prompts / messages are formatted for various scenarios.
**NOTE**: Outputs in terminal are color printed to show special tokens.
## Step 3: Building, and Configuring Llama Stack Distributions
- Please see our [Getting Started](getting_started.md) guide for more details on how to build and start a Llama Stack distribution.
### Step 3.1 Build
In the following steps, imagine we'll be working with a `Llama3.1-8B-Instruct` model. We will name our build `8b-instruct` to help us remember the config. We will start build our distribution (in the form of a Conda environment, or Docker image). In this step, we will specify:
- `name`: the name for our distribution (e.g. `8b-instruct`)
- `image_type`: our build image type (`conda | docker`)
- `distribution_spec`: our distribution specs for specifying API providers
- `description`: a short description of the configurations for the distribution
- `providers`: specifies the underlying implementation for serving each API endpoint
- `image_type`: `conda` | `docker` to specify whether to build the distribution in the form of Docker image or Conda environment.
At the end of build command, we will generate `<name>-build.yaml` file storing the build configurations.
After this step is complete, a file named `<name>-build.yaml` will be generated and saved at the output file path specified at the end of the command.
#### Building from scratch
- For a new user, we could start off with running `llama stack build` which will allow you to a interactively enter wizard where you will be prompted to enter build configurations.
```
llama stack build
```
Running the command above will allow you to fill in the configuration to build your Llama Stack distribution, you will see the following outputs.
```
> Enter an unique name for identifying your Llama Stack build distribution (e.g. my-local-stack): my-local-llama-stack
> Enter the image type you want your distribution to be built with (docker or conda): conda
Llama Stack is composed of several APIs working together. Let's configure the providers (implementations) you want to use for these APIs.
> Enter the API provider for the inference API: (default=meta-reference): meta-reference
> Enter the API provider for the safety API: (default=meta-reference): meta-reference
> Enter the API provider for the agents API: (default=meta-reference): meta-reference
> Enter the API provider for the memory API: (default=meta-reference): meta-reference
> Enter the API provider for the telemetry API: (default=meta-reference): meta-reference
> (Optional) Enter a short description for your Llama Stack distribution:
Build spec configuration saved at ~/.conda/envs/llamastack-my-local-llama-stack/my-local-llama-stack-build.yaml
```
#### Building from templates
- To build from alternative API providers, we provide distribution templates for users to get started building a distribution backed by different providers.
The following command will allow you to see the available templates and their corresponding providers.
```
llama stack build --list-templates
```
![alt text](https://github.com/meta-llama/llama-stack/docs/resources/list-templates.png)
You may then pick a template to build your distribution with providers fitted to your liking.
```
llama stack build --template tgi
```
```
$ llama stack build --template tgi
...
...
Build spec configuration saved at ~/.conda/envs/llamastack-tgi/tgi-build.yaml
You may now run `llama stack configure tgi` or `llama stack configure ~/.conda/envs/llamastack-tgi/tgi-build.yaml`
```
#### Building from config file
- In addition to templates, you may customize the build to your liking through editing config files and build from config files with the following command.
- The config file will be of contents like the ones in `llama_stack/distributions/templates/`.
```
$ cat llama_stack/templates/ollama/build.yaml
name: ollama
distribution_spec:
description: Like local, but use ollama for running LLM inference
providers:
inference: remote::ollama
memory: meta-reference
safety: meta-reference
agents: meta-reference
telemetry: meta-reference
image_type: conda
```
```
llama stack build --config llama_stack/templates/ollama/build.yaml
```
#### How to build distribution with Docker image
To build a docker image, you may start off from a template and use the `--image-type docker` flag to specify `docker` as the build image type.
```
llama stack build --template local --image-type docker
```
Alternatively, you may use a config file and set `image_type` to `docker` in our `<name>-build.yaml` file, and run `llama stack build <name>-build.yaml`. The `<name>-build.yaml` will be of contents like:
```
name: local-docker-example
distribution_spec:
description: Use code from `llama_stack` itself to serve all llama stack APIs
docker_image: null
providers:
inference: meta-reference
memory: meta-reference-faiss
safety: meta-reference
agentic_system: meta-reference
telemetry: console
image_type: docker
```
The following command allows you to build a Docker image with the name `<name>`
```
llama stack build --config <name>-build.yaml
Dockerfile created successfully in /tmp/tmp.I0ifS2c46A/DockerfileFROM python:3.10-slim
WORKDIR /app
...
...
You can run it with: podman run -p 8000:8000 llamastack-docker-local
Build spec configuration saved at ~/.llama/distributions/docker/docker-local-build.yaml
```
### Step 3.2 Configure
After our distribution is built (either in form of docker or conda environment), we will run the following command to
```
llama stack configure [ <docker-image-name> | <path/to/name.build.yaml>]
```
- For `conda` environments: <path/to/name.build.yaml> would be the generated build spec saved from Step 1.
- For `docker` images downloaded from Dockerhub, you could also use <docker-image-name> as the argument.
- Run `docker images` to check list of available images on your machine.
```
$ llama stack configure ~/.llama/distributions/conda/tgi-build.yaml
Configuring API: inference (meta-reference)
Enter value for model (existing: Llama3.1-8B-Instruct) (required):
Enter value for quantization (optional):
Enter value for torch_seed (optional):
Enter value for max_seq_len (existing: 4096) (required):
Enter value for max_batch_size (existing: 1) (required):
Configuring API: memory (meta-reference-faiss)
Configuring API: safety (meta-reference)
Do you want to configure llama_guard_shield? (y/n): y
Entering sub-configuration for llama_guard_shield:
Enter value for model (default: Llama-Guard-3-1B) (required):
Enter value for excluded_categories (default: []) (required):
Enter value for disable_input_check (default: False) (required):
Enter value for disable_output_check (default: False) (required):
Do you want to configure prompt_guard_shield? (y/n): y
Entering sub-configuration for prompt_guard_shield:
Enter value for model (default: Prompt-Guard-86M) (required):
Configuring API: agentic_system (meta-reference)
Enter value for brave_search_api_key (optional):
Enter value for bing_search_api_key (optional):
Enter value for wolfram_api_key (optional):
Configuring API: telemetry (console)
YAML configuration has been written to ~/.llama/builds/conda/tgi-run.yaml
```
After this step is successful, you should be able to find a run configuration spec in `~/.llama/builds/conda/tgi-run.yaml` with the following contents. You may edit this file to change the settings.
As you can see, we did basic configuration above and configured:
- inference to run on model `Llama3.1-8B-Instruct` (obtained from `llama model list`)
- Llama Guard safety shield with model `Llama-Guard-3-1B`
- Prompt Guard safety shield with model `Prompt-Guard-86M`
For how these configurations are stored as yaml, checkout the file printed at the end of the configuration.
Note that all configurations as well as models are stored in `~/.llama`
### Step 3.3 Run
Now, let's start the Llama Stack Distribution Server. You will need the YAML configuration file which was written out at the end by the `llama stack configure` step.
```
llama stack run ~/.llama/builds/conda/tgi-run.yaml
```
You should see the Llama Stack server start and print the APIs that it is supporting
```
$ llama stack run ~/.llama/builds/conda/tgi-run.yaml
> initializing model parallel with size 1
> initializing ddp with size 1
> initializing pipeline with size 1

This server is running a Llama model locally.
### Step 3.4 Test with Client
Once the server is setup, we can test it with a client to see the example outputs.
```
cd /path/to/llama-stack
conda activate <env> # any environment containing the llama-stack pip package will work
python -m llama_stack.apis.inference.client localhost 5000
```
This will run the chat completion client and query the distributions /inference/chat_completion API.
Here is an example output:
```
User>hello world, write me a 2 sentence poem about the moon
Assistant> Here's a 2-sentence poem about the moon:
The moon glows softly in the midnight sky,
A beacon of wonder, as it passes by.
```
Similarly you can test safety (if you configured llama-guard and/or prompt-guard shields) by:
```
python -m llama_stack.apis.safety.client localhost 5000
```
You can find more example scripts with client SDKs to talk with the Llama Stack server in our [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main/examples) repo.

# Downloading Models
The `llama` CLI tool helps you setup and use the Llama Stack. It should be available on your path after installing the `llama-stack` package.
## Installation
You have two ways to install Llama Stack:
1. **Install as a package**:
You can install the repository directly from [PyPI](https://pypi.org/project/llama-stack/) by running the following command:
```bash
pip install llama-stack
```
2. **Install from source**:
If you prefer to install from the source code, follow these steps:
```bash
mkdir -p ~/local
cd ~/local
git clone git@github.com:meta-llama/llama-stack.git
conda create -n myenv python=3.10
conda activate myenv
cd llama-stack
$CONDA_PREFIX/bin/pip install -e .
## Downloading models via CLI
You first need to have models downloaded locally.
To download any model you need the **Model Descriptor**.
This can be obtained by running the command
```
llama model list
```
You should see a table like this:
```
+----------------------------------+------------------------------------------+----------------+

+----------------------------------+------------------------------------------+----------------+
```
To download models, you can use the llama download command.
#### Downloading from [Meta](https://llama.meta.com/llama-downloads/)
Here is an example download command to get the 3B-Instruct/11B-Vision-Instruct model. You will need META_URL which can be obtained from [here](https://llama.meta.com/docs/getting_the_models/meta/)
Download the required checkpoints using the following commands:
```bash
# download the 8B model, this can be run on a single GPU
llama download --source meta --model-id Llama3.2-3B-Instruct --meta-url META_URL
# you can also get the 70B model, this will require 8 GPUs however
llama download --source meta --model-id Llama3.2-11B-Vision-Instruct --meta-url META_URL
# llama-agents have safety enabled by default. For this, you will need
# safety models -- Llama-Guard and Prompt-Guard
llama download --source meta --model-id Prompt-Guard-86M --meta-url META_URL
llama download --source meta --model-id Llama-Guard-3-1B --meta-url META_URL
```
#### Downloading from [Hugging Face](https://huggingface.co/meta-llama)
Essentially, the same commands above work, just replace `--source meta` with `--source huggingface`.
```bash
llama download --source huggingface --model-id Llama3.1-8B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama3.1-70B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama-Guard-3-1B --ignore-patterns *original*
llama download --source huggingface --model-id Prompt-Guard-86M --ignore-patterns *original*
```
**Important:** Set your environment variable `HF_TOKEN` or pass in `--hf-token` to the command to validate your access. You can find your token at [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens).
> **Tip:** Default for `llama download` is to run with `--ignore-patterns *.safetensors` since we use the `.pth` files in the `original` folder. For Llama Guard and Prompt Guard, however, we need safetensors. Hence, please run with `--ignore-patterns original` so that safetensors are downloaded and `.pth` files are ignored.

3. `stack`: Allows you to build and run a Llama Stack server. You can read more about this [here](../distribution_dev/building_distro.md).
### Sample Usage
```
llama --help
```
```
usage: llama [-h] {download,model,stack} ...
Welcome to the Llama CLI
options:

```
To download models, you can use the llama download command.
#### Downloading from [Meta](https://llama.meta.com/llama-downloads/)
Here is an example download command to get the 3B-Instruct/11B-Vision-Instruct model. You will need META_URL which can be obtained from [here](https://llama.meta.com/docs/getting_the_models/meta/)
Download the required checkpoints using the following commands:
```bash
# download the 8B model, this can be run on a single GPU
llama download --source meta --model-id Llama3.2-3B-Instruct --meta-url META_URL
# you can also get the 70B model, this will require 8 GPUs however
llama download --source meta --model-id Llama3.2-11B-Vision-Instruct --meta-url META_URL
# llama-agents have safety enabled by default. For this, you will need
# safety models -- Llama-Guard and Prompt-Guard
llama download --source meta --model-id Prompt-Guard-86M --meta-url META_URL
llama download --source meta --model-id Llama-Guard-3-1B --meta-url META_URL
```
#### Downloading from [Hugging Face](https://huggingface.co/meta-llama)
Essentially, the same commands above work, just replace `--source meta` with `--source huggingface`.
```bash
llama download --source huggingface --model-id Llama3.1-8B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama3.1-70B-Instruct --hf-token <HF_TOKEN>
llama download --source huggingface --model-id Llama-Guard-3-1B --ignore-patterns *original*
llama download --source huggingface --model-id Prompt-Guard-86M --ignore-patterns *original*
```
**Important:** Set your environment variable `HF_TOKEN` or pass in `--hf-token` to the command to validate your access. You can find your token at [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens).
> **Tip:** Default for `llama download` is to run with `--ignore-patterns *.safetensors` since we use the `.pth` files in the `original` folder. For Llama Guard and Prompt Guard, however, we need safetensors. Hence, please run with `--ignore-patterns original` so that safetensors are downloaded and `.pth` files are ignored.
## Understand the models
The `llama model` command helps you explore the models interface.
1. `download`: Download the model from different sources. (meta, huggingface)
2. `list`: Lists all the models available for download with hardware requirements to deploy the models.
3. `prompt-format`: Show llama model message formats.
4. `describe`: Describes all the properties of the model.
### Sample Usage
`llama model <subcommand> <options>`
```
llama model --help
```
```
usage: llama model [-h] {download,list,prompt-format,describe} ...
Work with llama models
options:
-h, --help show this help message and exit
model_subcommands:
{download,list,prompt-format,describe}
```
You can use the describe command to know more about a model:
```
llama model describe -m Llama3.2-3B-Instruct
```

# Developer Guide: Assemble a Llama Stack Distribution
This guide will walk you through the steps to get started with building a Llama Stack distributiom from scratch with your choice of API providers. Please see the [Getting Started Guide](https://llama-stack.readthedocs.io/en/latest/getting_started/index.html) if you just want the basic steps to start a Llama Stack distribution.
## Step 1. Build
### Llama Stack Build Options
```
llama stack build -h
```
We will start build our distribution (in the form of a Conda environment, or Docker image). In this step, we will specify:
- `name`: the name for our distribution (e.g. `my-stack`)
- `image_type`: our build image type (`conda | docker`)
- `distribution_spec`: our distribution specs for specifying API providers
- `description`: a short description of the configurations for the distribution
- `providers`: specifies the underlying implementation for serving each API endpoint
- `image_type`: `conda` | `docker` to specify whether to build the distribution in the form of Docker image or Conda environment.
After this step is complete, a file named `<name>-build.yaml` and template file `<name>-run.yaml` will be generated and saved at the output file path specified at the end of the command.
::::{tab-set}
:::{tab-item} Building from Scratch
- For a new user, we could start off with running `llama stack build` which will allow you to a interactively enter wizard where you will be prompted to enter build configurations.
```
llama stack build
> Enter a name for your Llama Stack (e.g. my-local-stack): my-stack
> Enter the image type you want your Llama Stack to be built as (docker or conda): conda
Llama Stack is composed of several APIs working together. Let's select
the provider types (implementations) you want to use for these APIs.
Tip: use <TAB> to see options for the providers.
> Enter provider for API inference: inline::meta-reference
> Enter provider for API safety: inline::llama-guard
> Enter provider for API agents: inline::meta-reference
> Enter provider for API memory: inline::faiss
> Enter provider for API datasetio: inline::meta-reference
> Enter provider for API scoring: inline::meta-reference
> Enter provider for API eval: inline::meta-reference
> Enter provider for API telemetry: inline::meta-reference
> (Optional) Enter a short description for your Llama Stack:
You can now edit ~/.llama/distributions/llamastack-my-local-stack/my-local-stack-run.yaml and run `llama stack run ~/.llama/distributions/llamastack-my-local-stack/my-local-stack-run.yaml`
```

:::{tab-item} Building from a template
- To build from alternative API providers, we provide distribution templates for users to get started building a distribution backed by different providers.
The following command will allow you to see the available templates and their corresponding providers.
```
llama stack build --list-templates
```
```

```
You may then pick a template to build your distribution with providers fitted to your liking.
For example, to build a distribution with TGI as the inference provider, you can run:
```
llama stack build --template tgi
```
```
$ llama stack build --template tgi
...
You can now edit ~/.llama/distributions/llamastack-tgi/tgi-run.yaml and run `llama stack run ~/.llama/distributions/llamastack-tgi/tgi-run.yaml`
```
:::
:::{tab-item} Building from a pre-existing build config file
- In addition to templates, you may customize the build to your liking through editing config files and build from config files with the following command.
- The config file will be of contents like the ones in `llama_stack/templates/*build.yaml`.
```
$ cat llama_stack/templates/ollama/build.yaml
name: ollama
distribution_spec:
description: Like local, but use ollama for running LLM inference
providers:
inference: remote::ollama
memory: inline::faiss
safety: inline::llama-guard
agents: meta-reference
telemetry: meta-reference
image_type: conda
```
```
llama stack build --config llama_stack/templates/ollama/build.yaml
```
:::
:::{tab-item} Building Docker
> [!TIP]
> Podman is supported as an alternative to Docker. Set `DOCKER_BINARY` to `podman` in your environment to use Podman.
To build a docker image, you may start off from a template and use the `--image-type docker` flag to specify `docker` as the build image type.
```
llama stack build --template ollama --image-type docker
```
```
$ llama stack build --template ollama --image-type docker
...
Dockerfile created successfully in /tmp/tmp.viA3a3Rdsg/DockerfileFROM python:3.10-slim
...
You can now edit ~/meta-llama/llama-stack/tmp/configs/ollama-run.yaml and run `llama stack run ~/meta-llama/llama-stack/tmp/configs/ollama-run.yaml`
```
After this step is successful, you should be able to find the built docker image and test it with `llama stack run <path/to/run.yaml>`.
:::
::::
## Step 2. Run
Now, let's start the Llama Stack Distribution Server. You will need the YAML configuration file which was written out at the end by the `llama stack build` step.
```

```
## Key Concepts
### API Provider
A Provider is what makes the API real -- they provide the actual implementation backing the API.
As an example, for Inference, we could have the implementation be backed by open source libraries like `[ torch | vLLM | TensorRT ]` as possible options.
A provider can also be just a pointer to a remote REST service -- for example, cloud providers or dedicated inference providers could serve these APIs.
### Distribution
A Distribution is where APIs and Providers are assembled together to provide a consistent whole to the end application developer. You can mix-and-match providers -- some could be backed by local code and some could be remote. As a hobbyist, you can serve a small model locally, but can choose a cloud provider for a large model. Regardless, the higher level APIs your app needs to work with don't need to change at all. You can even imagine moving across the server / mobile-device boundary as well always using the same uniform set of APIs for developing Generative AI applications.

# Getting Started
This guide will walk you though the steps to get started on end-to-end flow for LlamaStack. This guide mainly focuses on getting started with building a LlamaStack distribution, and starting up a LlamaStack server. Please see our [documentations](https://github.com/meta-llama/llama-stack/README.md) on what you can do with Llama Stack, and [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main) on examples apps built with Llama Stack.
## Installation
The `llama` CLI tool helps you setup and use the Llama toolchain & agentic systems. It should be available on your path after installing the `llama-stack` package.
You can install this repository as a [package](https://pypi.org/project/llama-stack/) with `pip install llama-stack`
If you want to install from source:
```bash
mkdir -p ~/local
cd ~/local
git clone git@github.com:meta-llama/llama-stack.git
conda create -n stack python=3.10
conda activate stack
cd llama-stack
$CONDA_PREFIX/bin/pip install -e .
```
For what you can do with the Llama CLI, please refer to [CLI Reference](./cli_reference.md).
## Quick Starting Llama Stack Server
### Starting up server via docker
We provide 2 pre-built Docker image of Llama Stack distribution, which can be found in the following links.
- [llamastack-local-gpu](https://hub.docker.com/repository/docker/llamastack/llamastack-local-gpu/general)
- This is a packaged version with our local meta-reference implementations, where you will be running inference locally with downloaded Llama model checkpoints.
- [llamastack-local-cpu](https://hub.docker.com/repository/docker/llamastack/llamastack-local-cpu/general)
- This is a lite version with remote inference where you can hook up to your favourite remote inference framework (e.g. ollama, fireworks, together, tgi) for running inference without GPU.
> [!NOTE]
> For GPU inference, you need to set these environment variables for specifying local directory containing your model checkpoints, and enable GPU inference to start running docker container.
```
export LLAMA_CHECKPOINT_DIR=~/.llama
```
> [!NOTE]
> `~/.llama` should be the path containing downloaded weights of Llama models.
To download and start running a pre-built docker container, you may use the following commands:
```
docker run -it -p 5000:5000 -v ~/.llama:/root/.llama --gpus=all llamastack/llamastack-local-gpu
```
> [!TIP]
> Pro Tip: We may use `docker compose up` for starting up a distribution with remote providers (e.g. TGI) using [llamastack-local-cpu](https://hub.docker.com/repository/docker/llamastack/llamastack-local-cpu/general). You can checkout [these scripts](https://github.com/meta-llama/llama-stack/llama_stack/distribution/docker/README.md) to help you get started.
### Build->Configure->Run Llama Stack server via conda
You may also build a LlamaStack distribution from scratch, configure it, and start running the distribution. This is useful for developing on LlamaStack.
**`llama stack build`**
- You'll be prompted to enter build information interactively.
```
llama stack build

### End-to-end flow of building, configuring, running, and testing a Distribution
#### Step 1. Build
In the following steps, imagine we'll be working with a `Meta-Llama3.1-8B-Instruct` model. We will name our build `8b-instruct` to help us remember the config. We will start build our distribution (in the form of a Conda environment, or Docker image). In this step, we will specify:
- `name`: the name for our distribution (e.g. `8b-instruct`)
- `image_type`: our build image type (`conda | docker`)
- `distribution_spec`: our distribution specs for specifying API providers
- `description`: a short description of the configurations for the distribution
- `providers`: specifies the underlying implementation for serving each API endpoint
- `image_type`: `conda` | `docker` to specify whether to build the distribution in the form of Docker image or Conda environment.
At the end of build command, we will generate `<name>-build.yaml` file storing the build configurations.
After this step is complete, a file named `<name>-build.yaml` will be generated and saved at the output file path specified at the end of the command.
#### Building from scratch
- For a new user, we could start off with running `llama stack build` which will allow you to a interactively enter wizard where you will be prompted to enter build configurations.
```
llama stack build
```
Running the command above will allow you to fill in the configuration to build your Llama Stack distribution, you will see the following outputs.
```
> Enter an unique name for identifying your Llama Stack build distribution (e.g. my-local-stack): 8b-instruct
> Enter the image type you want your distribution to be built with (docker or conda): conda
Llama Stack is composed of several APIs working together. Let's configure the providers (implementations) you want to use for these APIs.
> Enter the API provider for the inference API: (default=meta-reference): meta-reference
> Enter the API provider for the safety API: (default=meta-reference): meta-reference
> Enter the API provider for the agents API: (default=meta-reference): meta-reference
> Enter the API provider for the memory API: (default=meta-reference): meta-reference
> Enter the API provider for the telemetry API: (default=meta-reference): meta-reference
> (Optional) Enter a short description for your Llama Stack distribution:
Build spec configuration saved at ~/.conda/envs/llamastack-my-local-llama-stack/8b-instruct-build.yaml
```
**Ollama (optional)**
If you plan to use Ollama for inference, you'll need to install the server [via these instructions](https://ollama.com/download).
#### Building from templates
- To build from alternative API providers, we provide distribution templates for users to get started building a distribution backed by different providers.
The following command will allow you to see the available templates and their corresponding providers.
```
llama stack build --list-templates
```
![alt text](https://github.com/meta-llama/llama-stack/docs/resources/list-templates.png)
You may then pick a template to build your distribution with providers fitted to your liking.
```
llama stack build --template tgi
```
```
$ llama stack build --template tgi
...
...
Build spec configuration saved at ~/.conda/envs/llamastack-tgi/tgi-build.yaml
You may now run `llama stack configure tgi` or `llama stack configure ~/.conda/envs/llamastack-tgi/tgi-build.yaml`
```
#### Building from config file
- In addition to templates, you may customize the build to your liking through editing config files and build from config files with the following command.
- The config file will be of contents like the ones in `llama_stack/distributions/templates/`.
```
$ cat llama_stack/templates/ollama/build.yaml
name: ollama
distribution_spec:
description: Like local, but use ollama for running LLM inference
providers:
inference: remote::ollama
memory: meta-reference
safety: meta-reference
agents: meta-reference
telemetry: meta-reference
image_type: conda
```
```
llama stack build --config llama_stack/templates/ollama/build.yaml
```
#### How to build distribution with Docker image
> [!TIP]
> Podman is supported as an alternative to Docker. Set `DOCKER_BINARY` to `podman` in your environment to use Podman.
To build a docker image, you may start off from a template and use the `--image-type docker` flag to specify `docker` as the build image type.
```
llama stack build --template tgi --image-type docker
```
Alternatively, you may use a config file and set `image_type` to `docker` in our `<name>-build.yaml` file, and run `llama stack build <name>-build.yaml`. The `<name>-build.yaml` will be of contents like:
```
name: local-docker-example
distribution_spec:
description: Use code from `llama_stack` itself to serve all llama stack APIs
docker_image: null
providers:
inference: meta-reference
memory: meta-reference-faiss
safety: meta-reference
agentic_system: meta-reference
telemetry: console
image_type: docker
```
The following command allows you to build a Docker image with the name `<name>`
```
llama stack build --config <name>-build.yaml
Dockerfile created successfully in /tmp/tmp.I0ifS2c46A/DockerfileFROM python:3.10-slim
WORKDIR /app
...
...
You can run it with: podman run -p 8000:8000 llamastack-docker-local
Build spec configuration saved at ~/.llama/distributions/docker/docker-local-build.yaml
```
### Step 2. Configure
After our distribution is built (either in form of docker or conda environment), we will run the following command to
```
llama stack configure [ <docker-image-name> | <path/to/name.build.yaml>]
```
- For `conda` environments: <path/to/name.build.yaml> would be the generated build spec saved from Step 1.
- For `docker` images downloaded from Dockerhub, you could also use <docker-image-name> as the argument.
- Run `docker images` to check list of available images on your machine.
```
$ llama stack configure tgi
Configuring API: inference (meta-reference)
Enter value for model (existing: Meta-Llama3.1-8B-Instruct) (required):

YAML configuration has been written to ~/.llama/builds/conda/tgi-run.yaml
```
After this step is successful, you should be able to find a run configuration spec in `~/.llama/builds/conda/tgi-run.yaml` with the following contents. You may edit this file to change the settings.
As you can see, we did basic configuration above and configured:
- inference to run on model `Meta-Llama3.1-8B-Instruct` (obtained from `llama model list`)
- Llama Guard safety shield with model `Llama-Guard-3-1B`
- Prompt Guard safety shield with model `Prompt-Guard-86M`
For how these configurations are stored as yaml, checkout the file printed at the end of the configuration.
Note that all configurations as well as models are stored in `~/.llama`
### Step 3. Run
Now, let's start the Llama Stack Distribution Server. You will need the YAML configuration file which was written out at the end by the `llama stack configure` step.
```
llama stack run tgi
```
You should see the Llama Stack server start and print the APIs that it is supporting
```
$ llama stack run tgi

> initializing ddp with size 1
> initializing pipeline with size 1

This server is running a Llama model locally.
### Step 4. Test with Client
Once the server is setup, we can test it with a client to see the example outputs.
```
cd /path/to/llama-stack
conda activate <env> # any environment containing the llama-stack pip package will work
python -m llama_stack.apis.inference.client localhost 5000
```
This will run the chat completion client and query the distributions /inference/chat_completion API.
Here is an example output:
```
User>hello world, write me a 2 sentence poem about the moon
Assistant> Here's a 2-sentence poem about the moon:
The moon glows softly in the midnight sky,
A beacon of wonder, as it passes by.
```
Similarly you can test safety (if you configured llama-guard and/or prompt-guard shields) by:
```
python -m llama_stack.apis.safety.client localhost 5000
```
Check out our client SDKs for connecting to Llama Stack server in your preferred language, you can choose from [python](https://github.com/meta-llama/llama-stack-client-python), [node](https://github.com/meta-llama/llama-stack-client-node), [swift](https://github.com/meta-llama/llama-stack-client-swift), and [kotlin](https://github.com/meta-llama/llama-stack-client-kotlin) programming languages to quickly build your applications.
You can find more example scripts with client SDKs to talk with the Llama Stack server in our [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main/examples) repo.

# LocalInference
# iOS SDK
We offer both remote and on-device use of Llama Stack in Swift via two components:
1. [llama-stack-client-swift](https://github.com/meta-llama/llama-stack-client-swift/)
2. [LocalInferenceImpl](https://github.com/meta-llama/llama-stack/tree/main/llama_stack/providers/inline/ios/inference)
```{image} ../../../../_static/remote_or_local.gif
:alt: Seamlessly switching between local, on-device inference and remote hosted inference
:width: 412px
:align: center
```
## Remote Only
If you don't want to run inference on-device, then you can connect to any hosted Llama Stack distribution with #1.
1. Add `https://github.com/meta-llama/llama-stack-client-swift/` as a Package Dependency in Xcode
2. Add `LlamaStackClient` as a framework to your app target
3. Call an API:
```swift
import LlamaStackClient
let agents = RemoteAgents(url: URL(string: "http://localhost:5000")!)
let request = Components.Schemas.CreateAgentTurnRequest(
agent_id: agentId,
messages: [
.UserMessage(Components.Schemas.UserMessage(
content: .case1("Hello Llama!"),
role: .user
))
],
session_id: self.agenticSystemSessionId,
stream: true
)
for try await chunk in try await agents.createTurn(request: request) {
let payload = chunk.event.payload
// ...
```
Check out [iOSCalendarAssistant](https://github.com/meta-llama/llama-stack-apps/tree/main/examples/ios_calendar_assistant) for a complete app demo.
## LocalInference
LocalInference provides a local inference implementation powered by [executorch](https://github.com/pytorch/executorch/).
Llama Stack currently supports on-device inference for iOS with Android coming soon. You can run on-device inference on Android today using [executorch](https://github.com/pytorch/executorch/tree/main/examples/demo-apps/android/LlamaDemo), PyTorchs on-device inference library.
## Installation
The APIs *work the same as remote*  the only difference is you'll instead use the `LocalAgents` / `LocalInference` classes and pass in a `DispatchQueue`:
```swift
private let runnerQueue = DispatchQueue(label: "org.llamastack.stacksummary")
let inference = LocalInference(queue: runnerQueue)
let agents = LocalAgents(inference: self.inference)
```
Check out [iOSCalendarAssistantWithLocalInf](https://github.com/meta-llama/llama-stack-apps/tree/main/examples/ios_calendar_assistant) for a complete app demo.

# Remote vLLM Distribution
The `llamastack/distribution-remote-vllm` distribution consists of the following provider configurations.
| **API** | **Inference** | **Agents** | **Memory** | **Safety** | **Telemetry** |
|----------------- |---------------- |---------------- |------------------------------------ |---------------- |---------------- |
| **Provider(s)** | remote::vllm | meta-reference | remote::pgvector, remote::chromadb | meta-reference | meta-reference |
You can use this distribution if you have GPUs and want to run an independent vLLM server container for running inference.
## Using Docker Compose
You can use `docker compose` to start a vLLM container and Llama Stack server container together.
> [!NOTE]
> This assumes you have access to GPU to start a vLLM server with access to your GPU.
```bash
$ cd distributions/remote-vllm; docker compose up
```
You will see outputs similar to following ---
```
<TO BE FILLED>
```
To kill the server
```bash
docker compose down
```
## Starting vLLM and Llama Stack separately
You may want to start a vLLM server and connect with Llama Stack manually. There are two ways to start a vLLM server and connect with Llama Stack.
#### Start vLLM server.
```bash
docker run --runtime nvidia --gpus all \
-v ~/.cache/huggingface:/root/.cache/huggingface \
--env "HUGGING_FACE_HUB_TOKEN=<secret>" \
-p 8000:8000 \
--ipc=host \
vllm/vllm-openai:latest \
--model meta-llama/Llama-3.1-8B-Instruct
```
Please check the [vLLM Documentation](https://docs.vllm.ai/en/v0.5.5/serving/deploying_with_docker.html) for more details.
#### Start Llama Stack server pointing to your vLLM server
We have provided a template `run.yaml` file in the `distributions/remote-vllm` directory. Please make sure to modify the `inference.provider_id` to point to your vLLM server endpoint. As an example, if your vLLM server is running on `http://127.0.0.1:8000`, your `run.yaml` file should look like the following:
```yaml
inference:
- provider_id: vllm0
provider_type: remote::vllm
config:
url: http://127.0.0.1:8000
```
**Via Conda**
If you are using Conda, you can build and run the Llama Stack server with the following commands:
```bash
cd distributions/remote-vllm
llama stack build --template remote_vllm --image-type conda
llama stack run run.yaml
```
**Via Docker**
You can use the Llama Stack Docker image to start the server with the following command:
```bash
docker run --network host -it -p 5000:5000 \
-v ~/.llama:/root/.llama \
-v ./gpu/run.yaml:/root/llamastack-run-remote-vllm.yaml \

:maxdepth: 2
:hidden:
distributions/self_hosted_distro/index
distributions/remote_hosted_distro/index
distributions/ondevice_distro/index
```
At the end of the guide, you will have learned how to:
- get a Llama Stack server up and running
- set up an agent (with tool-calling and vector stores) that works with the above server
To see more example apps built using Llama Stack, see [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main).
## Step 1. Starting Up Llama Stack Server
### Decide Your Build Type
There are two ways to start a Llama Stack:
- **Docker**: we provide a number of pre-built Docker containers allowing you to get started instantly. If you are focused on application development, we recommend this option.
- **Conda**: the `llama` CLI provides a simple set of commands to build, configure and run a Llama Stack server containing the exact combination of providers you wish. We have provided various templates to make getting started easier.
Both of these provide options to run model inference using our reference implementations, Ollama, TGI, vLLM or even remote providers like Fireworks, Together, Bedrock, etc.
### Decide Your Inference Provider
Running inference on the underlying Llama model is one of the most critical requirements. Depending on what hardware you have available, you have various options. Note that each option have different necessary prerequisites.
- **Do you have access to a machine with powerful GPUs?**
If so, we suggest:
- [distribution-meta-reference-gpu](https://llama-stack.readthedocs.io/en/latest/getting_started/distributions/self_hosted_distro/meta-reference-gpu.html)
- [distribution-tgi](https://llama-stack.readthedocs.io/en/latest/getting_started/distributions/tgi.html)
- **Are you running on a "regular" desktop machine?**
If so, we suggest:
- [distribution-ollama](https://llama-stack.readthedocs.io/en/latest/getting_started/distributions/self_hosted_distro/ollama.html)
- **Do you have an API key for a remote inference provider like Fireworks, Together, etc.?** If so, we suggest:
- [distribution-together](https://llama-stack.readthedocs.io/en/latest/getting_started/distributions/remote_hosted_distro/together.html)
- [distribution-fireworks](https://llama-stack.readthedocs.io/en/latest/getting_started/distributions/remote_hosted_distro/fireworks.html)
- **Do you want to run Llama Stack inference on your iOS / Android device** If so, we suggest:
- [iOS](https://llama-stack.readthedocs.io/en/latest/getting_started/distributions/ondevice_distro/ios_sdk.html)
- [Android](https://github.com/meta-llama/llama-stack-client-kotlin) (coming soon)
Please see our pages in detail for the types of distributions we offer:
1. [Self-Hosted Distribution](./distributions/self_hosted_distro/index.md): If you want to run Llama Stack inference on your local machine.
2. [Remote-Hosted Distribution](./distributions/remote_hosted_distro/index.md): If you want to connect to a remote hosted inference provider.
3. [On-device Distribution](./distributions/ondevice_distro/index.md): If you want to run Llama Stack inference on your iOS / Android device.
### Quick Start Commands

##### Troubleshooting
- If you encounter any issues, search through our [GitHub Issues](https://github.com/meta-llama/llama-stack/issues), or file an new issue.
- Use `--port <PORT>` flag to use a different port number. For docker run, update the `-p <PORT>:<PORT>` flag.
## Step 2. Run Llama Stack App
### Chat Completion Test
Once the server is set up, we can test it with a client to verify it's working correctly. The following command will send a chat completion request to the server's `/inference/chat_completion` API:
```bash
$ curl http://localhost:5000/inference/chat_completion \
-H "Content-Type: application/json" \
-d '{
"model_id": "Llama3.1-8B-Instruct",
"messages": [
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Write me a 2 sentence poem about the moon"}
],
"sampling_params": {"temperature": 0.7, "seed": 42, "max_tokens": 512}
}'
Output:
{'completion_message': {'role': 'assistant',
'content': 'The moon glows softly in the midnight sky, \nA beacon of wonder, as it catches the eye.',
'stop_reason': 'out_of_tokens',
'tool_calls': []},
'logprobs': null}
```
### Run Agent App
To run an agent app, check out examples demo scripts with client SDKs to talk with the Llama Stack server in our [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main/examples) repo. To run a simple agent app:
```bash
$ git clone git@github.com:meta-llama/llama-stack-apps.git
$ cd llama-stack-apps
$ pip install -r requirements.txt
$ python -m examples.agents.client <host> <port>
```
You will see outputs of the form --
```
User> I am planning a trip to Switzerland, what are the top 3 places to visit?
inference> Switzerland is a beautiful country with a rich history, stunning landscapes, and vibrant culture. Here are three must-visit places to add to your itinerary:
...
User> What is so special about #1?
inference> Jungfraujoch, also known as the "Top of Europe," is a unique and special place for several reasons:
...
User> What other countries should I consider to club?

# Llama Stack
Llama Stack defines and standardizes the building blocks needed to bring generative AI applications to market. It empowers developers building agentic applications by giving them options to operate in various environments (on-prem, cloud, single-node, on-device) while relying on a standard API interface and the same DevEx that is certified by Meta.

It empowers developers building agentic applications by giving them options to operate in various environments (on-prem, cloud, single-node, on-device) while relying on a standard API interface and developer experience that's certified by Meta.
The Llama Stack defines and standardizes the building blocks needed to bring generative AI applications to market. These blocks span the entire development lifecycle: from model training and fine-tuning, through product evaluation, to building and running AI agents in production. Beyond definition, we are building providers for the Llama Stack APIs. These were developing open-source versions and partnering with providers, ensuring developers can assemble AI solutions using consistent, interlocking pieces across platforms. The ultimate goal is to accelerate innovation in the AI space.
The Stack APIs are rapidly improving but still a work-in-progress. We invite feedback as well as direct contributions.

## APIs
The Llama Stack consists of the following set of APIs:
The set of APIs in Llama Stack can be roughly split into two broad categories:
- Inference
- Safety
- Memory
- Agentic System
- Evaluation
- Post Training
- Synthetic Data Generation
- Reward Scoring
Each of the APIs themselves is a collection of REST endpoints.
- APIs focused on Application development
- Inference
- Safety
- Memory
- Agentic System
- Evaluation
- APIs focused on Model development
- Evaluation
- Post Training
- Synthetic Data Generation
- Reward Scoring
Each API is a collection of REST endpoints.
## API Providers
A Provider is what makes the API real -- they provide the actual implementation backing the API.
A Provider is what makes the API real they provide the actual implementation backing the API.
As an example, for Inference, we could have the implementation be backed by open source libraries like [ torch | vLLM | TensorRT ] as possible options.
A provider can also be just a pointer to a remote REST service -- for example, cloud providers or dedicated inference providers could serve these APIs.
A provider can also be a relay to a remote REST service ex. cloud providers or dedicated inference providers that serve these APIs.
## Distribution
A Distribution is where APIs and Providers are assembled together to provide a consistent whole to the end application developer. You can mix-and-match providers -- some could be backed by local code and some could be remote. As a hobbyist, you can serve a small model locally, but can choose a cloud provider for a large model. Regardless, the higher level APIs your app needs to work with don't need to change at all. You can even imagine moving across the server / mobile-device boundary as well always using the same uniform set of APIs for developing Generative AI applications.

"\n",
"1. **Physical Characteristics**: Llamas are large, even-toed ungulates with a distinctive appearance. They have a long neck, a small head, and a soft, woolly coat that can be various colors, including white, brown, gray, and black.\n",
"2. **Size**: Llamas typically grow to be between 5 and 6 feet (1.5 to 1.8 meters) tall at the shoulder and weigh between 280 and 450 pounds (127 to 204 kilograms).\n",
"3. **Habitat**: Llamas are native to the Andean highlands, where they live in herds and roam freely. They are well adapted to the harsh, high-altitude climate of the Andes.\n",
"4. **Diet**: Llamas are herbivores and feed on a variety of plants, including grasses, leaves, and shrubs. They are known for their ability to digest plant material that other animals cannot.\n",
"5. **Behavior**: Llamas are social animals and live in herds. They are known for their intelligence, curiosity, and strong sense of self-preservation.\n",
"6. **Purpose**: Llamas have been domesticated for thousands of years and have been used for a variety of purposes, including:\n",
"\t* **Pack animals**: Llamas are often used as pack animals, carrying goods and supplies over long distances.\n",
"\t* **Fiber production**: Llama wool is highly valued for its softness, warmth, and durability.\n",
"\t* **Meat**: Llama meat is consumed in some parts of the world, particularly in South America.\n",
"\t* **Companionship**: Llamas are often kept as pets or companions, due to their gentle nature and intelligence.\n",
"\n",
"Overall, llamas are fascinating animals that have been an integral part of Andean culture for thousands of years.\u001b[0m\n"

"## 3. Custom Tool Creation\n",
"\n",
"Let's create a custom weather tool:\n",
"\n",
"#### Key Highlights:\n",
"- **`WeatherTool` Class**: A custom tool that processes weather information requests, supporting location and optional date parameters.\n",
"- **Agent Creation**: The `create_weather_agent` function sets up an agent equipped with the `WeatherTool`, allowing for weather queries in natural language.\n",
"- **Simulation of API Call**: The `run_impl` method simulates fetching weather data. This method can be replaced with an actual API integration for real-world usage.\n",
"- **Interactive Example**: The `weather_example` function shows how to use the agent to handle user queries regarding the weather, providing step-by-step responses."

"\n",
"- breaking a task down and performing multi-step reasoning.\n",
"- using tools to perform some actions\n",
" - built-in: the model has built-in knowledge of tools like search or code interpreter\n",
" - zero-shot: the model can learn to call tools using previously unseen, in-context tool definitions\n",
"- providing system level safety protections using models like Llama Guard.\n",
"\n",
"An agentic app requires a few components:\n",
"- ability to run inference on the underlying Llama series of models\n",
"- ability to run safety checks using the Llama Guard series of models\n",
"- ability to execute tools, including a code execution environment, and loop using the model's multi-step reasoning process\n",
"\n",
"All of these components are now offered by a single Llama Stack Distribution. Llama Stack defines and standardizes these components and many others that are needed to make building Generative AI applications smoother. Various implementations of these APIs are then assembled together via a **Llama Stack Distribution**.\n",

"- **`WeatherTool` Class**: A custom tool that processes weather information requests, supporting location and optional date parameters.\n",
"- **Agent Creation**: The `create_weather_agent` function sets up an agent equipped with the `WeatherTool`, allowing for weather queries in natural language.\n",
"- **Simulation of API Call**: The `run_impl` method simulates fetching weather data. This method can be replaced with an actual API integration for real-world usage.\n",
"- **Interactive Example**: The `weather_example` function shows how to use the agent to handle user queries regarding the weather, providing step-by-step responses."

# Ollama Quickstart Guide
This guide will walk you through setting up an end-to-end workflow with Llama Stack with ollama, enabling you to perform text generation using the `Llama3.2-1B-Instruct` model. Follow these steps to get started quickly.
If you're looking for more specific topics like tool calling or agent setup, we have a [Zero to Hero Guide](#next-steps) that covers everything from Tool Calling to Agents in detail. Feel free to skip to the end to explore the advanced topics you're interested in.
> If you'd prefer not to set up a local server, explore our notebook on [tool calling with the Together API](Tool_Calling101_Using_Together's_Llama_Stack_Server.ipynb). This guide will show you how to leverage Together.ai's Llama Stack Server API, allowing you to get started with Llama Stack without the need for a locally built and running server.
## Table of Contents
1. [Setup ollama](#setup-ollama)
2. [Install Dependencies and Set Up Environment](#install-dependencies-and-set-up-environment)
3. [Build, Configure, and Run Llama Stack](#build-configure-and-run-llama-stack)
4. [Run Ollama Model](#run-ollama-model)
5. [Next Steps](#next-steps)
---
## Setup ollama
1. **Download Ollama App**:
- Go to [https://ollama.com/download](https://ollama.com/download).
- Download and unzip `Ollama-darwin.zip`.
- Run the `Ollama` application.
2. **Download the Ollama CLI**:
- Ensure you have the `ollama` command line tool by downloading and installing it from the same website.
3. **Verify Installation**:
- Open the terminal and run:
```bash
ollama run llama3.2:1b
```
---
## Install Dependencies and Set Up Environment
1. **Create a Conda Environment**:
- Create a new Conda environment with Python 3.11:
```bash
conda create -n hack python=3.11
```
- Activate the environment:
```bash
conda activate hack
```
2. **Install ChromaDB**:
- Install `chromadb` using `pip`:
```bash
pip install chromadb
```
3. **Run ChromaDB**:
- Start the ChromaDB server:
```bash
chroma run --host localhost --port 8000 --path ./my_chroma_data
```
4. **Install Llama Stack**:
- Open a new terminal and install `llama-stack`:
```bash
conda activate hack
pip install llama-stack
```
---
## Build, Configure, and Run Llama Stack
1. **Build the Llama Stack**:
- Build the Llama Stack using the `ollama` template:
```bash
llama stack build --template ollama --image-type conda
```
2. **Edit Configuration**:
- Modify the `ollama-run.yaml` file located at `/Users/yourusername/.llama/distributions/llamastack-ollama/ollama-run.yaml`:
- Change the `chromadb` port to `8000`.
- Remove the `pgvector` section if present.
3. **Run the Llama Stack**:
- Run the stack with the configured YAML file:
```bash
llama stack run /path/to/your/distro/llamastack-ollama/ollama-run.yaml --port 5050
```
The server will start and listen on `http://localhost:5050`.
---
## Testing with `curl`
After setting up the server, open a new terminal window and verify it's working by sending a `POST` request using `curl`:
```bash
curl http://localhost:5050/inference/chat_completion \
-H "Content-Type: application/json" \
-d '{
"model": "llama3.2:1b",
"messages": [
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Write me a 2-sentence poem about the moon"}
],
"sampling_params": {"temperature": 0.7, "seed": 42, "max_tokens": 512}
}'
```
**Expected Output:**
```json
{
"completion_message": {
"role": "assistant",
"content": "The moon glows softly in the midnight sky,\nA beacon of wonder, as it catches the eye.",
"stop_reason": "out_of_tokens",
"tool_calls": []
},
"logprobs": null
}
```
---
## Testing with Python
You can also interact with the Llama Stack server using a simple Python script. Below is an example:
### 1. Active Conda Environment and Install Required Python Packages
The `llama-stack-client` library offers a robust and efficient python methods for interacting with the Llama Stack server.
```bash
conda activate your-llama-stack-conda-env
pip install llama-stack-client
```
### 2. Create Python Script (`test_llama_stack.py`)
```bash
touch test_llama_stack.py
```
### 3. Create a Chat Completion Request in Python
```python
from llama_stack_client import LlamaStackClient
# Initialize the client
client = LlamaStackClient(base_url="http://localhost:5050")
# Create a chat completion request
response = client.inference.chat_completion(
messages=[
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Write a two-sentence poem about llama."}
],
model="llama3.2:1b",
)
# Print the response
print(response.completion_message.content)
```
### 4. Run the Python Script
```bash
python test_llama_stack.py
```
**Expected Output:**
```
The moon glows softly in the midnight sky,
A beacon of wonder, as it catches the eye.
```
With these steps, you should have a functional Llama Stack setup capable of generating text using the specified model. For more detailed information and advanced configurations, refer to some of our documentation below.
This command initializes the model to interact with your local Llama Stack instance.
