-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.

 ## 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
+- Agents
-- Evaluation
+- 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.

+# 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.)

 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:

-    - [Inline Providers](https://github.com/meta-llama/llama-stack/tree/main/llama_stack/providers/inline)
+    - {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.

+# 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",

+            "repetition_penalty": 1.0
+        }
+    }
+}
+```
+
+**Example Application EvalTaskConfig**

-## 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.

+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

+# 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()
+```

-## Introduction
 
-Llama Stack Distributions are pre-built Docker containers/Conda environments that assemble APIs and Providers to provide a consistent whole to the end application developer.
+<!-- self_hosted_distro/index -->
+<!-- remote_hosted_distro/index -->
+<!-- ondevice_distro/index -->
 
-These distributions allow you to mix-and-match providers - some could be backed by local code and some could be remote. This flexibility enables you to choose the optimal setup for your use case, such as serving a small model locally while using a cloud provider for larger models, all while maintaining a consistent API interface for your application.
+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.
-## 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](./self_hosted_distro/meta-reference-gpu.md)
+  - {dockerhub}`distribution-remote-vllm` ([Guide](self_hosted_distro/remote-vllm))
-  - [distribution-tgi](./self_hosted_distro/tgi.md)
+  - {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:
-  - [distribution-ollama](./self_hosted_distro/ollama.md)
+  - {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:
-  - [distribution-together](./remote_hosted_distro/together.md)
+  - {dockerhub}`distribution-together` ([Guide](remote_hosted_distro/index))
-  - [distribution-fireworks](./remote_hosted_distro/fireworks.md)
+  - {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](./ondevice_distro/ios_sdk.md)
+  - [iOS SDK](ondevice_distro/ios_sdk)
-  - [Android](https://github.com/meta-llama/llama-stack-client-kotlin) (coming soon)
+  - Android (coming soon)
 
-Please see our pages in detail for the types of distributions we offer:
+You can also build your own [custom distribution](building_distro).
-
-1. [Self-Hosted Distributions](./self_hosted_distro/index.md): If you want to run Llama Stack inference on your local machine.
-2. [Remote-Hosted Distributions](./remote_hosted_distro/index.md): If you want to connect to a remote hosted inference provider.
-3. [On-device Distributions](./ondevice_distro/index.md): If you want to run Llama Stack inference on your iOS / Android device.

 # 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.
+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 Stack APIs are rapidly improving but still a work-in-progress. We invite feedback as well as direct contributions.
-
 
 ```{image} ../_static/llama-stack.png
 :alt: Llama Stack
 :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
+## Philosophy
-  - Inference
-  - Safety
-  - Memory
-  - Agentic System
-  - Evaluation
 
-- APIs focused on Model development
+### Service-oriented design
-  - Evaluation
-  - Post Training
-  - Synthetic Data Generation
-  - Reward Scoring
 
-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.

+# Llama Stack: from Zero to Hero
+
+Llama-Stack allows you to configure your distribution from various providers, allowing you to focus on going from zero to production super fast.
+
+This guide will walk you through how to build a local distribution, using Ollama as an inference provider.
+
+We also have a set of notebooks walking you through how to use Llama-Stack APIs:
+
+- Inference
+- Prompt Engineering
+- Chatting with Images
+- Tool Calling
+- Memory API for RAG
+- Safety API
+- Agentic API
+
+Below, we will learn how to get started with Ollama as an inference provider, please note the steps for configuring your provider will vary a little depending on the service. However, the user experience will remain universal-this is the power of Llama-Stack.
+
+Prototype locally using Ollama, deploy to the cloud with your favorite provider or own deployment. Use any API from any provider while focussing on development.

+After this step, you will see the console output:
-   - Modify the `ollama-run.yaml` file located at `/Users/yourusername/.llama/distributions/llamastack-ollama/ollama-run.yaml`:
+
-     - Change the `chromadb` port to `8000`.
