This repository contains the Llama Stack API specifications as well as API Providers and Llama Stack Distributions.
Llama Stack defines and standardizes the set of core building blocks needed to bring generative AI applications to market. These building blocks are presented in the form of interoperable APIs with a broad set of Service Providers providing their implementations.
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 very much work in progress and we invite feedback as well as direct contributions.
Our goal is to provide pre-packaged implementations which can be operated in a variety of deployment environments: developers start iterating with Desktops or their mobile devices and can seamlessly transition to on-prem or public cloud deployments. At every point in this transition, the same set of APIs and the same developer experience is available.
> ⚠️ **Note**
> The Stack APIs are rapidly improving, but still very much work in progress and we invite feedback as well as direct contributions.
## APIs
The Llama Stack consists of the following set of APIs:
We have working implementations of the following APIs today:
- Inference
- Safety
- Memory
- Agentic System
- Evaluation
- Agents
- Eval
- Telemetry
Alongside these APIs, we also related APIs for operating with associated resources (see [Concepts](https://llama-stack.readthedocs.io/en/latest/concepts/index.html#resources)):
- Models
- Shields
- Memory Banks
- EvalTasks
- Datasets
- Scoring Functions
We are also working on the following APIs which will be released soon:
- Post Training
- Synthetic Data Generation
- Reward Scoring
Each of the APIs themselves is a collection of REST endpoints.
## Philosophy
## API Providers
### Service-oriented design
A Provider is what makes the API real -- they provide the actual implementation backing the API.
Unlike other frameworks, Llama Stack is built with a service-oriented, REST API-first approach. Such a design not only allows for seamless transitions from a local to remote deployments, but also forces the design to be more declarative. We believe this restriction can result in a much simpler, robust developer experience. This will necessarily trade-off against expressivity however if we get the APIs right, it can lead to a very powerful platform.
As an example, for Inference, we could have the implementation be backed by open source libraries like `[ torch | vLLM | TensorRT ]` as possible options.
### Composability
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.
We expect the set of APIs we design to be composable. An Agent abstractly depends on { Inference, Memory, Safety } APIs but does not care about the actual implementation details. Safety itself may require model inference and hence can depend on the Inference API.
### Turnkey one-stop solutions
## Llama Stack Distribution
We expect to provide turnkey solutions for popular deployment scenarios. It should be easy to deploy a Llama Stack server on AWS or on a private data center. Either of these should allow a developer to get started with powerful agentic apps, model evaluations or fine-tuning services in a matter of minutes. They should all result in the same uniform observability and developer experience.
### Focus on Llama models
As a Meta initiated project, we have started by explicitly focusing on Meta's Llama series of models. Supporting the broad set of open models is no easy task and we want to start with models we understand best.
### Supporting the Ecosystem
There is a vibrant ecosystem of Providers which provide efficient inference or scalable vector stores or powerful observability solutions. We want to make sure it is easy for developers to pick and choose the best implementations for their use cases. We also want to make sure it is easy for new Providers to onboard and participate in the ecosystem.
Additionally, we have designed every element of the Stack such that APIs as well as Resources (like Models) can be federated.
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.

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.

# Core Concepts
Given Llama Stack's service-oriented philosophy, a few concepts and workflows arise which may not feel completely natural in the LLM landscape, especially if you are coming with a background in other frameworks.
## APIs
A Llama Stack API is described as a collection of REST endpoints. We currently support the following APIs:
- **Inference**: run inference with a LLM
- **Safety**: apply safety policies to the output at a Systems (not only model) level
- **Agents**: run multi-step agentic workflows with LLMs with tool usage, memory (RAG), etc.
- **Memory**: store and retrieve data for RAG, chat history, etc.
- **DatasetIO**: interface with datasets and data loaders
- **Scoring**: evaluate outputs of the system
- **Eval**: generate outputs (via Inference or Agents) and perform scoring
- **Telemetry**: collect telemetry data from the system
We are working on adding a few more APIs to complete the application lifecycle. These will include:
- **Batch Inference**: run inference on a dataset of inputs
- **Batch Agents**: run agents on a dataset of inputs
- **Post Training**: fine-tune a Llama model
- **Synthetic Data Generation**: generate synthetic data for model development
## API Providers
The goal of Llama Stack is to build an ecosystem where users can easily swap out different implementations for the same API. Obvious examples for these include
- LLM inference providers (e.g., Fireworks, Together, AWS Bedrock, etc.),
- Vector databases (e.g., ChromaDB, Weaviate, Qdrant, etc.),
- Safety providers (e.g., Meta's Llama Guard, AWS Bedrock Guardrails, etc.)
Providers come in two flavors:
- **Remote**: the provider runs as a separate service external to the Llama Stack codebase. Llama Stack contains a small amount of adapter code.
- **Inline**: the provider is fully specified and implemented within the Llama Stack codebase. It may be a simple wrapper around an existing library, or a full fledged implementation within Llama Stack.
## Resources
Some of these APIs are associated with a set of **Resources**. Here is the mapping of APIs to resources:
- **Inference**, **Eval** and **Post Training** are associated with `Model` resources.
- **Safety** is associated with `Shield` resources.
- **Memory** is associated with `Memory Bank` resources.
- **DatasetIO** is associated with `Dataset` resources.
- **Scoring** is associated with `ScoringFunction` resources.
- **Eval** is associated with `Model` and `EvalTask` resources.
Furthermore, we allow these resources to be **federated** across multiple providers. For example, you may have some Llama models served by Fireworks while others are served by AWS Bedrock. Regardless, they will all work seamlessly with the same uniform Inference API provided by Llama Stack.
```{admonition} Registering Resources
:class: tip
Given this architecture, it is necessary for the Stack to know which provider to use for a given resource. This means you need to explicitly _register_ resources (including models) before you can use them with the associated APIs.
```
## Distributions
While there is a lot of flexibility to mix-and-match providers, often users will work with a specific set of providers (hardware support, contractual obligations, etc.) We therefore need to provide a _convenient shorthand_ for such collections. We call this shorthand a **Llama Stack Distribution** or a **Distro**. One can think of it as specific pre-packaged versions of the Llama Stack. Here are some examples:
**Remotely Hosted Distro**: These are the simplest to consume from a user perspective. You can simply obtain the API key for these providers, point to a URL and have _all_ Llama Stack APIs working out of the box. Currently, [Fireworks](https://fireworks.ai/) and [Together](https://together.xyz/) provide such easy-to-consume Llama Stack distributions.
**Locally Hosted Distro**: You may want to run Llama Stack on your own hardware. Typically though, you still need to use Inference via an external service. You can use providers like HuggingFace TGI, Cerebras, Fireworks, Together, etc. for this purpose. Or you may have access to GPUs and can run a [vLLM](https://github.com/vllm-project/vllm) instance. If you "just" have a regular desktop machine, you can use [Ollama](https://ollama.com/) for inference. To provide convenient quick access to these options, we provide a number of such pre-configured locally-hosted Distros.
**On-device Distro**: Finally, you may want to run Llama Stack directly on an edge device (mobile phone or a tablet.) We provide Distros for iOS and Android (coming soon.)

# Developer Guide: Adding a New API Provider
# Adding a New API Provider
This guide contains references to walk you through adding a new API provider.
### 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:
- [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)
- {repopath}`Remote Providers::llama_stack/providers/remote`
- {repopath}`Inline Providers::llama_stack/providers/inline`
3. [Build a Llama Stack distribution](https://llama-stack.readthedocs.io/en/latest/distribution_dev/building_distro.html) with your API provider.
3. [Build a Llama Stack distribution](https://llama-stack.readthedocs.io/en/latest/distributions/building_distro.html) with your API provider.
4. Test your code!
### Testing your newly added API providers
## Testing your newly added API providers
1. Start with an _integration test_ for your provider. That means we will instantiate the real provider, pass it real configuration and if it is a remote service, we will actually hit the remote service. We **strongly** discourage mocking for these tests at the provider level. Llama Stack is first and foremost about integration so we need to make sure stuff works end-to-end. See [llama_stack/providers/tests/inference/test_inference.py](../llama_stack/providers/tests/inference/test_inference.py) for an example.

# Evaluations
The Llama Stack Evaluation flow allows you to run evaluations on your GenAI application datasets or pre-registered benchmarks.
We introduce a set of APIs in Llama Stack for supporting running evaluations of LLM applications.
- `/datasetio` + `/datasets` API
- `/scoring` + `/scoring_functions` API
- `/eval` + `/eval_tasks` API
This guide goes over the sets of APIs and developer experience flow of using Llama Stack to run evaluations for different use cases.
## Evaluation Concepts
The Evaluation APIs are associated with a set of Resources as shown in the following diagram. Please visit the Resources section in our [Core Concepts](../concepts/index.md) guide for better high-level understanding.
![Eval Concepts](./resources/eval-concept.png)
- **DatasetIO**: defines interface with datasets and data loaders.
- Associated with `Dataset` resource.
- **Scoring**: evaluate outputs of the system.
- Associated with `ScoringFunction` resource. We provide a suite of out-of-the box scoring functions and also the ability for you to add custom evaluators. These scoring functions are the core part of defining an evaluation task to output evaluation metrics.
- **Eval**: generate outputs (via Inference or Agents) and perform scoring.
- Associated with `EvalTask` resource.
## Running Evaluations
Use the following decision tree to decide how to use LlamaStack Evaluation flow.
![Eval Flow](./resources/eval-flow.png)
```{admonition} Note on Benchmark v.s. Application Evaluation
:class: tip
- **Benchmark Evaluation** is a well-defined eval-task consisting of `dataset` and `scoring_function`. The generation (inference or agent) will be done as part of evaluation.
- **Application Evaluation** assumes users already have app inputs & generated outputs. Evaluation will purely focus on scoring the generated outputs via scoring functions (e.g. LLM-as-judge).
```
The following examples give the quick steps to start running evaluations using the llama-stack-client CLI.
#### Benchmark Evaluation CLI
Usage: There are 2 inputs necessary for running a benchmark eval
- `eval-task-id`: the identifier associated with the eval task. Each `EvalTask` is parametrized by
- `dataset_id`: the identifier associated with the dataset.
- `List[scoring_function_id]`: list of scoring function identifiers.
- `eval-task-config`: specifies the configuration of the model / agent to evaluate on.
```
llama-stack-client eval run_benchmark <eval-task-id> \
--eval-task-config ~/eval_task_config.json \
--visualize
```
#### Application Evaluation CLI
Usage: For running application evals, you will already have available datasets in hand from your application. You will need to specify:
- `scoring-fn-id`: List of ScoringFunction identifiers you wish to use to run on your application.
- `Dataset` used for evaluation:
- (1) `--dataset-path`: path to local file system containing datasets to run evaluation on
- (2) `--dataset-id`: pre-registered dataset in Llama Stack
- (Optional) `--scoring-params-config`: optionally parameterize scoring functions with custom params (e.g. `judge_prompt`, `judge_model`, `parsing_regexes`).
```
llama-stack-client eval run_scoring <scoring_fn_id_1> <scoring_fn_id_2> ... <scoring_fn_id_n>
--dataset-path <path-to-local-dataset> \
--output-dir ./
```
#### Defining EvalTaskConfig
The `EvalTaskConfig` are user specified config to define:
1. `EvalCandidate` to run generation on:
- `ModelCandidate`: The model will be used for generation through LlamaStack /inference API.
- `AgentCandidate`: The agentic system specified by AgentConfig will be used for generation through LlamaStack /agents API.
2. Optionally scoring function params to allow customization of scoring function behaviour. This is useful to parameterize generic scoring functions such as LLMAsJudge with custom `judge_model` / `judge_prompt`.
**Example Benchmark EvalTaskConfig**
```json
{
"type": "benchmark",
"eval_candidate": {
"type": "model",
"model": "Llama3.2-3B-Instruct",
"sampling_params": {
"strategy": "greedy",
"temperature": 0,
"top_p": 0.95,
"top_k": 0,
"max_tokens": 0,
"repetition_penalty": 1.0
}
}
}
```
**Example Application EvalTaskConfig**
```json
{
"type": "app",
"eval_candidate": {
"type": "model",
"model": "Llama3.1-405B-Instruct",
"sampling_params": {

}
},

## 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.

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.
This guide will walk you through the steps to get started with building a Llama Stack distribution from scratch with your choice of API providers.
## Step 1. Build
### Llama Stack Build Options
## Llama Stack Build
In order to build your own distribution, we recommend you clone the `llama-stack` repository.
```
git clone git@github.com:meta-llama/llama-stack.git
cd llama-stack
pip install -e .
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`)
@ -240,7 +247,7 @@ After this step is successful, you should be able to find the built docker image

## Step 2. Run
## Running your Stack server
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.

# Configuring a Stack
The Llama Stack runtime configuration is specified as a YAML file. Here is a simplied version of an example configuration file for the Ollama distribution:
```{dropdown} Sample Configuration File
```yaml
version: 2
conda_env: ollama
apis:
- agents
- inference
- memory
- safety
- telemetry
providers:
inference:
- provider_id: ollama
provider_type: remote::ollama
config:
url: ${env.OLLAMA_URL:http://localhost:11434}
memory:
- provider_id: faiss
provider_type: inline::faiss
config:
kvstore:
type: sqlite
namespace: null
db_path: ${env.SQLITE_STORE_DIR:~/.llama/distributions/ollama}/faiss_store.db
safety:
- provider_id: llama-guard
provider_type: inline::llama-guard
config: {}
agents:
- provider_id: meta-reference
provider_type: inline::meta-reference
config:
persistence_store:
type: sqlite
namespace: null
db_path: ${env.SQLITE_STORE_DIR:~/.llama/distributions/ollama}/agents_store.db
telemetry:
- provider_id: meta-reference
provider_type: inline::meta-reference
config: {}
metadata_store:
namespace: null
type: sqlite
db_path: ${env.SQLITE_STORE_DIR:~/.llama/distributions/ollama}/registry.db
models:
- metadata: {}
model_id: ${env.INFERENCE_MODEL}
provider_id: ollama
provider_model_id: null
shields: []
```
Let's break this down into the different sections. The first section specifies the set of APIs that the stack server will serve:
```yaml
apis:
- agents
- inference
- memory
- safety
- telemetry
```
## Providers
Next up is the most critical part: the set of providers that the stack will use to serve the above APIs. Consider the `inference` API:
```yaml
providers:
inference:
- provider_id: ollama
provider_type: remote::ollama
config:
url: ${env.OLLAMA_URL:http://localhost:11434}
```
A few things to note:
- A _provider instance_ is identified with an (identifier, type, configuration) tuple. The identifier is a string you can choose freely.
- You can instantiate any number of provider instances of the same type.
- The configuration dictionary is provider-specific. Notice that configuration can reference environment variables (with default values), which are expanded at runtime. When you run a stack server (via docker or via `llama stack run`), you can specify `--env OLLAMA_URL=http://my-server:11434` to override the default value.
## Resources
Finally, let's look at the `models` section:
```yaml
models:
- metadata: {}
model_id: ${env.INFERENCE_MODEL}
provider_id: ollama
provider_model_id: null
```
A Model is an instance of a "Resource" (see [Concepts](../concepts/index)) and is associated with a specific inference provider (in this case, the provider with identifier `ollama`). This is an instance of a "pre-registered" model. While we always encourage the clients to always register models before using them, some Stack servers may come up a list of "already known and available" models.
What's with the `provider_model_id` field? This is an identifier for the model inside the provider's model catalog. Contrast it with `model_id` which is the identifier for the same model for Llama Stack's purposes. For example, you may want to name "llama3.2:vision-11b" as "image_captioning_model" when you use it in your Stack interactions. When omitted, the server will set `provider_model_id` to be the same as `model_id`.
## Extending to handle Safety
Configuring Safety can be a little involved so it is instructive to go through an example.
The Safety API works with the associated Resource called a `Shield`. Providers can support various kinds of Shields. Good examples include the [Llama Guard](https://ai.meta.com/research/publications/llama-guard-llm-based-input-output-safeguard-for-human-ai-conversations/) system-safety models, or [Bedrock Guardrails](https://aws.amazon.com/bedrock/guardrails/).
To configure a Bedrock Shield, you would need to add:
- A Safety API provider instance with type `remote::bedrock`
- A Shield resource served by this provider.
```yaml
...
providers:
safety:
- provider_id: bedrock
provider_type: remote::bedrock
config:
aws_access_key_id: ${env.AWS_ACCESS_KEY_ID}
aws_secret_access_key: ${env.AWS_SECRET_ACCESS_KEY}
...
shields:
- provider_id: bedrock
params:
guardrailVersion: ${env.GUARDRAIL_VERSION}
provider_shield_id: ${env.GUARDRAIL_ID}
...
```
The situation is more involved if the Shield needs _Inference_ of an associated model. This is the case with Llama Guard. In that case, you would need to add:
- A Safety API provider instance with type `inline::llama-guard`
- An Inference API provider instance for serving the model.
- A Model resource associated with this provider.
- A Shield resource served by the Safety provider.
The yaml configuration for this setup, assuming you were using vLLM as your inference server, would look like:
```yaml
...
providers:
safety:
- provider_id: llama-guard
provider_type: inline::llama-guard
config: {}
inference:
# this vLLM server serves the "normal" inference model (e.g., llama3.2:3b)
- provider_id: vllm-0
provider_type: remote::vllm
config:
url: ${env.VLLM_URL:http://localhost:8000}
# this vLLM server serves the llama-guard model (e.g., llama-guard:3b)
- provider_id: vllm-1
provider_type: remote::vllm
config:
url: ${env.SAFETY_VLLM_URL:http://localhost:8001}
...
models:
- metadata: {}
model_id: ${env.INFERENCE_MODEL}
provider_id: vllm-0
provider_model_id: null
- metadata: {}
model_id: ${env.SAFETY_MODEL}
provider_id: vllm-1
provider_model_id: null
shields:
- provider_id: llama-guard
shield_id: ${env.SAFETY_MODEL} # Llama Guard shields are identified by the corresponding LlamaGuard model
provider_shield_id: null
...
```

# Using Llama Stack as a Library
If you are planning to use an external service for Inference (even Ollama or TGI counts as external), it is often easier to use Llama Stack as a library. This avoids the overhead of setting up a server. For [example](https://github.com/meta-llama/llama-stack-client-python/blob/main/src/llama_stack_client/lib/direct/test.py):
```python
from llama_stack_client.lib.direct.direct import LlamaStackDirectClient
client = await LlamaStackDirectClient.from_template('ollama')
await client.initialize()
```
This will parse your config and set up any inline implementations and remote clients needed for your implementation.
Then, you can access the APIs like `models` and `inference` on the client and call their methods directly:
```python
response = await client.models.list()
print(response)
```
```python
response = await client.inference.chat_completion(
messages=[UserMessage(content="What is the capital of France?", role="user")],
model="Llama3.1-8B-Instruct",
stream=False,
)
print("\nChat completion response:")
print(response)
```
If you've created a [custom distribution](https://llama-stack.readthedocs.io/en/latest/distributions/building_distro.html), you can also use the run.yaml configuration file directly:
```python
client = await LlamaStackDirectClient.from_config(config_path)
await client.initialize()
```

You can instantiate a Llama Stack in one of the following ways:
- **As a Library**: this is the simplest, especially if you are using an external inference service. See [Using Llama Stack as a Library](importing_as_library)
- **Docker**: we provide a number of pre-built Docker containers so you can start a Llama Stack server instantly. You can also build your own custom Docker container.
- **Conda**: finally, you can build a custom Llama Stack server using `llama stack build` containing the exact combination of providers you wish. We have provided various templates to make getting started easier.
Which templates / distributions to choose depends on the hardware you have for running LLM inference.
- **Do you have access to a machine with powerful GPUs?**
If so, we suggest:
- {dockerhub}`distribution-remote-vllm` ([Guide](self_hosted_distro/remote-vllm))
- {dockerhub}`distribution-meta-reference-gpu` ([Guide](self_hosted_distro/meta-reference-gpu))
- {dockerhub}`distribution-tgi` ([Guide](self_hosted_distro/tgi))
- **Are you running on a "regular" desktop machine?**
If so, we suggest:
- {dockerhub}`distribution-ollama` ([Guide](self_hosted_distro/ollama))
- **Do you have an API key for a remote inference provider like Fireworks, Together, etc.?** If so, we suggest:
- {dockerhub}`distribution-together` ([Guide](remote_hosted_distro/index))
- {dockerhub}`distribution-fireworks` ([Guide](remote_hosted_distro/index))
- **Do you want to run Llama Stack inference on your iOS / Android device** If so, we suggest:
- [iOS SDK](ondevice_distro/ios_sdk)
- Android (coming soon)
You can also build your own [custom distribution](building_distro).

# Bedrock Distribution
### Connect to a Llama Stack Bedrock Endpoint
- You may connect to Amazon Bedrock APIs for running LLM inference
The `llamastack/distribution-bedrock` distribution consists of the following provider configurations.
| **API** | **Inference** | **Agents** | **Memory** | **Safety** | **Telemetry** |
|----------------- |--------------- |---------------- |---------------- |---------------- |---------------- |
| **Provider(s)** | remote::bedrock | meta-reference | meta-reference | remote::bedrock | meta-reference |
### Docker: Start the Distribution (Single Node CPU)
> [!NOTE]
> This assumes you have valid AWS credentials configured with access to Amazon Bedrock.
```
$ cd distributions/bedrock && docker compose up
```
Make sure in your `run.yaml` file, your inference provider is pointing to the correct AWS configuration. E.g.
```
inference:
- provider_id: bedrock0
provider_type: remote::bedrock
config:
aws_access_key_id: <AWS_ACCESS_KEY_ID>
aws_secret_access_key: <AWS_SECRET_ACCESS_KEY>
aws_session_token: <AWS_SESSION_TOKEN>
region_name: <AWS_REGION>
```
### Conda llama stack run (Single Node CPU)
```bash
llama stack build --template bedrock --image-type conda
# -- modify run.yaml with valid AWS credentials
llama stack run ./run.yaml
```
### (Optional) Update Model Serving Configuration
Use `llama-stack-client models list` to check the available models served by Amazon Bedrock.
```
$ llama-stack-client models list
+------------------------------+------------------------------+---------------+------------+
| identifier | llama_model | provider_id | metadata |
+==============================+==============================+===============+============+
| Llama3.1-8B-Instruct | meta.llama3-1-8b-instruct-v1:0 | bedrock0 | {} |

# 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.
### Step 0. Prerequisite - Downloading Models
Please make sure you have llama model checkpoints downloaded in `~/.llama` before proceeding. See [installation guide](https://llama-stack.readthedocs.io/en/latest/cli_reference/download_models.html) here to download the models.
```
$ ls ~/.llama/checkpoints
Llama3.2-3B-Instruct:int4-qlora-eo8
```
### Step 1. Start the Distribution
#### (Option 1) Start with Docker
```
$ cd distributions/meta-reference-quantized-gpu && 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-quantized-gpu --yaml_config /root/my-run.yaml
```
#### (Option 2) Start with Conda
1. Install the `llama` CLI. See [CLI Reference](https://llama-stack.readthedocs.io/en/latest/cli_reference/index.html)
2. Build the `meta-reference-quantized-gpu` distribution
```
$ llama stack build --template meta-reference-quantized-gpu --image-type conda
```
3. Start running distribution
```
$ cd distributions/meta-reference-quantized-gpu
$ llama stack run ./run.yaml
```

# Getting Started
# Quick Start
```{toctree}
:maxdepth: 2
:hidden:
In this guide, we'll through how you can use the Llama Stack client SDK to build a simple RAG agent.
distributions/self_hosted_distro/index
distributions/remote_hosted_distro/index
distributions/ondevice_distro/index
```
The most critical requirement for running the agent is running inference on the underlying Llama model. Depending on what hardware (GPUs) you have available, you have various options. We will use `Ollama` for this purpose as it is the easiest to get started with and yet robust.
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.

##### 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:
First, let's set up some environment variables that we will use in the rest of the guide. Note that if you open up a new terminal, you will need to set these again.
```bash
$ curl http://localhost:5000/alpha/inference/chat-completion \
-H "Content-Type: application/json" \
-d '{
"model_id": "meta-llama/Llama-3.1-8B-Instruct",
"messages": [
export INFERENCE_MODEL="meta-llama/Llama-3.2-3B-Instruct"
# ollama names this model differently, and we must use the ollama name when loading the model
export OLLAMA_INFERENCE_MODEL="llama3.2:3b-instruct-fp16"
export LLAMA_STACK_PORT=5001
```
### 1. Start Ollama
```bash
ollama run $OLLAMA_INFERENCE_MODEL --keepalive 60m
```
By default, Ollama keeps the model loaded in memory for 5 minutes which can be too short. We set the `--keepalive` flag to 60 minutes to enspagents/agenure the model remains loaded for sometime.
### 2. Start the Llama Stack server
Llama Stack is based on a client-server architecture. It consists of a server which can be configured very flexibly so you can mix-and-match various providers for its individual API components -- beyond Inference, these include Memory, Agents, Telemetry, Evals and so forth.
```bash
docker run \
-it \
-p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
-v ~/.llama:/root/.llama \
llamastack/distribution-ollama \
--port $LLAMA_STACK_PORT \
--env INFERENCE_MODEL=$INFERENCE_MODEL \
--env OLLAMA_URL=http://host.docker.internal:11434
```
Configuration for this is available at `distributions/ollama/run.yaml`.
### 3. Use the Llama Stack client SDK
You can interact with the Llama Stack server using the `llama-stack-client` CLI or via the Python SDK.
```bash
pip install llama-stack-client
```
Let's use the `llama-stack-client` CLI to check the connectivity to the server.
```bash
llama-stack-client --endpoint http://localhost:$LLAMA_STACK_PORT models list
┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━┓
┃ identifier ┃ provider_id ┃ provider_resource_id ┃ metadata ┃
┡━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━╇━━━━━━━━━━━━━╇━━━━━━━━━━━━━━━━━━━━━━━━━━━╇━━━━━━━━━━┩
│ meta-llama/Llama-3.2-3B-Instruct │ ollama │ llama3.2:3b-instruct-fp16 │ │
└──────────────────────────────────┴─────────────┴───────────────────────────┴──────────┘
```
You can test basic Llama inference completion using the CLI too.
```bash
llama-stack-client --endpoint http://localhost:$LLAMA_STACK_PORT \
inference chat_completion \
--message "hello, what model are you?"
```
Here is a simple example to perform chat completions using Python instead of the CLI.
```python
import os
from llama_stack_client import LlamaStackClient
client = LlamaStackClient(base_url=f"http://localhost:{os.environ['LLAMA_STACK_PORT']}")
# List available models
models = client.models.list()
print(models)
response = client.inference.chat_completion(
model_id=os.environ["INFERENCE_MODEL"],
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}
{"role": "user", "content": "Write a haiku about coding"}
]
)
print(response.completion_message.content)
```
### Run Agent App
### 4. Your first RAG agent
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:
Here is an example of a simple RAG agent that uses the Llama Stack client SDK.
```bash
$ git clone git@github.com:meta-llama/llama-stack-apps.git
$ cd llama-stack-apps
$ pip install -r requirements.txt
```python
import asyncio
import os
$ python -m examples.agents.client <host> <port>
from llama_stack_client import LlamaStackClient
from llama_stack_client.lib.agents.agent import Agent
from llama_stack_client.lib.agents.event_logger import EventLogger
from llama_stack_client.types import Attachment
from llama_stack_client.types.agent_create_params import AgentConfig
async def run_main():
urls = ["chat.rst", "llama3.rst", "datasets.rst", "lora_finetune.rst"]
attachments = [
Attachment(
content=f"https://raw.githubusercontent.com/pytorch/torchtune/main/docs/source/tutorials/{url}",
mime_type="text/plain",
)
for i, url in enumerate(urls)
]
client = LlamaStackClient(base_url=f"http://localhost:{os.environ['LLAMA_STACK_PORT']}")
agent_config = AgentConfig(
model=os.environ["INFERENCE_MODEL"],
instructions="You are a helpful assistant",
tools=[{"type": "memory"}], # enable Memory aka RAG
)
agent = Agent(client, agent_config)
session_id = agent.create_session("test-session")
print(f"Created session_id={session_id} for Agent({agent.agent_id})")
user_prompts = [
(
"I am attaching documentation for Torchtune. Help me answer questions I will ask next.",
attachments,
),
(
"What are the top 5 topics that were explained? Only list succinct bullet points.",
None,
),
]
for prompt, attachments in user_prompts:
response = agent.create_turn(
messages=[{"role": "user", "content": prompt}],
attachments=attachments,
session_id=session_id,
)
async for log in EventLogger().log(response):
log.print()
if __name__ == "__main__":
asyncio.run(run_main())
```
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:

# 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 developer experience that's certified by Meta.
The Stack APIs are rapidly improving but still a work-in-progress. We invite feedback as well as direct contributions.
Llama Stack defines and standardizes the set of core building blocks needed to bring generative AI applications to market. These building blocks are presented in the form of interoperable APIs with a broad set of Service Providers providing their implementations.
```{image} ../_static/llama-stack.png
:alt: Llama Stack
:width: 600px
:align: center
:width: 400px
```
## APIs
Our goal is to provide pre-packaged implementations which can be operated in a variety of deployment environments: developers start iterating with Desktops or their mobile devices and can seamlessly transition to on-prem or public cloud deployments. At every point in this transition, the same set of APIs and the same developer experience is available.
The set of APIs in Llama Stack can be roughly split into two broad categories:
```{note}
The Stack APIs are rapidly improving but still a work-in-progress. We invite feedback as well as direct contributions.
```
- APIs focused on Application development
- Inference
- Safety
- Memory
- Agentic System
- Evaluation
## Philosophy
- APIs focused on Model development
- Evaluation
- Post Training
- Synthetic Data Generation
- Reward Scoring
### Service-oriented design
Each API is a collection of REST endpoints.
Unlike other frameworks, Llama Stack is built with a service-oriented, REST API-first approach. Such a design not only allows for seamless transitions from a local to remote deployments, but also forces the design to be more declarative. We believe this restriction can result in a much simpler, robust developer experience. This will necessarily trade-off against expressivity however if we get the APIs right, it can lead to a very powerful platform.
## API Providers
### Composability
A Provider is what makes the API real – they provide the actual implementation backing the API.
We expect the set of APIs we design to be composable. An Agent abstractly depends on { Inference, Memory, Safety } APIs but does not care about the actual implementation details. Safety itself may require model inference and hence can depend on the Inference API.
As an example, for Inference, we could have the implementation be backed by open source libraries like [ torch | vLLM | TensorRT ] as possible options.
### Turnkey one-stop solutions
A provider can also be a relay to a remote REST service – ex. cloud providers or dedicated inference providers that serve these APIs.
We expect to provide turnkey solutions for popular deployment scenarios. It should be easy to deploy a Llama Stack server on AWS or on a private data center. Either of these should allow a developer to get started with powerful agentic apps, model evaluations or fine-tuning services in a matter of minutes. They should all result in the same uniform observability and developer experience.
## Distribution
### Focus on Llama models
As a Meta initiated project, we have started by explicitly focusing on Meta's Llama series of models. Supporting the broad set of open models is no easy task and we want to start with models we understand best.
### Supporting the Ecosystem
There is a vibrant ecosystem of Providers which provide efficient inference or scalable vector stores or powerful observability solutions. We want to make sure it is easy for developers to pick and choose the best implementations for their use cases. We also want to make sure it is easy for new Providers to onboard and participate in the ecosystem.
Additionally, we have designed every element of the Stack such that APIs as well as Resources (like Models) can be federated.
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.
## Supported Llama Stack Implementations
### API Providers
| **API Provider Builder** | **Environments** | **Agents** | **Inference** | **Memory** | **Safety** | **Telemetry** |
Llama Stack already has a number of "adapters" available for some popular Inference and Memory (Vector Store) providers. For other APIs (particularly Safety and Agents), we provide *reference implementations* you can use to get started. We expect this list to grow over time. We are slowly onboarding more providers to the ecosystem as we get more confidence in the APIs.

"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."
"Let's create the `BraveSearch` class, which encapsulates the logic for making web search queries using the Brave Search API and formatting the response. The class includes methods for sending requests, processing results, and extracting relevant data to support the integration with an AI toolchain."

"Chunk(content=\"_steps * num_devices``\\n\\nGradient accumulation is especially useful when you can fit at least one sample in your GPU. In this case, artificially increasing the batch by\\naccumulating gradients might give you faster training speeds than using other memory optimization techniques that trade-off memory for speed, like :ref:`activation checkpointing <glossary_act_ckpt>`.\\n\\n*Sounds great! How do I use it?*\\n\\nAll of our finetuning recipes support simulating larger batch sizes by accumulating gradients.

# Llama Stack: from Zero to Hero
Llama Stack defines and standardizes the set of core building blocks needed to bring generative AI applications to market. These building blocks are presented in the form of interoperable APIs with a broad set of Providers providing their implementations. These building blocks are assembled into Distributions which are easy for developers to get from zero to production.
This guide will walk you through an end-to-end workflow with Llama Stack with Ollama as the inference provider and ChromaDB as the memory provider. Please note the steps for configuring your provider and distribution will vary a little depending on the services you use. However, the user experience will remain universal - this is the power of Llama-Stack.
If you're looking for more specific topics, 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 notebook 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.

---
## Setup ollama
1. **Download Ollama App**:
- Go to [https://ollama.com/download](https://ollama.com/download).
- Follow instructions based on the OS you are on. For example, if you are on a Mac, download and unzip `Ollama-darwin.zip`.
- Run the `Ollama` application.
1. **Download the Ollama CLI**:
Ensure you have the `ollama` command line tool by downloading and installing it from the same website.
1. **Start ollama server**:
Open the terminal and run:
```
ollama serve
```
1. **Run the model**:
Open the terminal and run:
```bash
ollama run llama3.2:3b-instruct-fp16 --keepalive -1m
```
**Note**:
- The supported models for llama stack for now is listed in [here](https://github.com/meta-llama/llama-stack/blob/main/llama_stack/providers/remote/inference/ollama/ollama.py#L43)
- `keepalive -1m` is used so that ollama continues to keep the model in memory indefinitely. Otherwise, ollama frees up memory and you would have to run `ollama run` again.
---
## Install Dependencies and Set Up Environment
1. **Create a Conda Environment**:
Create a new Conda environment with Python 3.10:
```bash
conda create -n ollama python=3.10
```
Activate the environment:
```bash
conda activate ollama
```
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 ollama
pip install llama-stack==0.0.55
```
---
## 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
```
**Expected Output:**
```
...
Build Successful! Next steps:
1. Set the environment variables: LLAMASTACK_PORT, OLLAMA_URL, INFERENCE_MODEL, SAFETY_MODEL
2. `llama stack run /Users/<username>/.llama/distributions/llamastack-ollama/ollama-run.yaml
```
3. **Set the ENV variables by exporting them to the terminal**:
```bash
export OLLAMA_URL="http://localhost:11434"
export LLAMA_STACK_PORT=5051
export INFERENCE_MODEL="meta-llama/Llama-3.2-3B-Instruct"
export SAFETY_MODEL="meta-llama/Llama-Guard-3-1B"
```
3. **Run the Llama Stack**:
Run the stack with command shared by the API from earlier:
```bash
llama stack run ollama \
--port $LLAMA_STACK_PORT \
--env INFERENCE_MODEL=$INFERENCE_MODEL \
--env SAFETY_MODEL=$SAFETY_MODEL \
--env OLLAMA_URL=$OLLAMA_URL
```
Note: Everytime you run a new model with `ollama run`, you will need to restart the llama stack. Otherwise it won't see the new model.
The server will start and listen on `http://localhost:5051`.
---
## Test with `llama-stack-client` CLI
After setting up the server, open a new terminal window and install the llama-stack-client package.
1. Install the llama-stack-client package
```bash
conda activate ollama
pip install llama-stack-client
```
2. Configure the CLI to point to the llama-stack server.
```bash
llama-stack-client configure --endpoint http://localhost:5051
```
**Expected Output:**
```bash
Done! You can now use the Llama Stack Client CLI with endpoint http://localhost:5051
```
3. Test the CLI by running inference:
```bash
llama-stack-client inference chat-completion --message "Write me a 2-sentence poem about the moon"
```
**Expected Output:**
```bash
ChatCompletionResponse(
completion_message=CompletionMessage(
content='Here is a 2-sentence poem about the moon:\n\nSilver crescent shining bright in the night,\nA beacon of wonder, full of gentle light.',
role='assistant',
stop_reason='end_of_turn',
tool_calls=[]
),
logprobs=None
)
```
## Test 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:$LLAMA_STACK_PORT/inference/chat_completion \
-H "Content-Type: application/json" \
-d '{
"model": "Llama3.2-3B-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}
}'
```
You can check the available models with the command `llama-stack-client models list`.
**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
}
```
---
## Test with Python
You can also interact with the Llama Stack server using a simple Python script. Below is an example:
### 1. Activate 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 ollama
pip install llama-stack-client
```
Note, the client library gets installed by default if you install the server library
### 2. Create Python Script (`test_llama_stack.py`)
```bash
touch test_llama_stack.py
```
### 3. Create a Chat Completion Request in Python
In `test_llama_stack.py`, write the following code:
```python
from llama_stack_client import LlamaStackClient
# Initialize the client
client = LlamaStackClient(base_url="http://localhost:5051")
# Create a chat completion request
response = client.inference.chat_completion(
messages=[
{"role": "system", "content": "You are a friendly assistant."},
{"role": "user", "content": "Write a two-sentence poem about llama."}
],
model_id=MODEL_NAME,
)
# 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.

# 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.
1. **Download the Ollama CLI**:
- Ensure you have the `ollama` command line tool by downloading and installing it from the same website.
1. **Start ollama server**:
- Open the terminal and run:
```
ollama serve
```
1. **Run the model**:
- Open the terminal and run:
```bash
ollama run llama3.2:3b-instruct-fp16
```
**Note**: The supported models for llama stack for now is listed in [here](https://github.com/meta-llama/llama-stack/blob/main/llama_stack/providers/remote/inference/ollama/ollama.py#L43)
---
## 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
```
Note:
1. Everytime you run a new model with `ollama run`, you will need to restart the llama stack. Otherwise it won't see the new model
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": "Llama3.2-3B-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}
}'
```
You can check the available models with the command `llama-stack-client models list`.
**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.
