Llama Stack

Quick Start | Documentation | Colab Notebook

Llama Stack defines and standardizes the core building blocks that simplify AI application development. It codified best practices across the Llama ecosystem. More specifically, it provides

• Unified API layer for Inference, RAG, Agents, Tools, Safety, Evals, and Telemetry.
• Plugin architecture to support the rich ecosystem of implementations of the different APIs in different environments like local development, on-premises, cloud, and mobile.
• Prepackaged verified distributions which offer a one-stop solution for developers to get started quickly and reliably in any environment
• Multiple developer interfaces like CLI and SDKs for Python, Typescript, iOS, and Android
• Standalone applications as examples for how to build production-grade AI applications with Llama Stack

Llama Stack Benefits

• Flexible Options: Developers can choose their preferred infrastructure without changing APIs and enjoy flexible deployment choice.
• Consistent Experience: With its unified APIs Llama Stack makes it easier to build, test, and deploy AI applications with consistent application behavior.
• Robust Ecosystem: Llama Stack is already integrated with distribution partners (cloud providers, hardware vendors, and AI-focused companies) that offer tailored infrastructure, software, and services for deploying Llama models.

By reducing friction and complexity, Llama Stack empowers developers to focus on what they do best: building transformative generative AI applications.

API Providers

Distributions

A Llama Stack Distribution (or "distro") is a pre-configured bundle of provider implementations for each API component. Distributions make it easy to get started with a specific deployment scenario - you can begin with a local development setup (eg. ollama) and seamlessly transition to production (eg. Fireworks) without changing your application code. Here are some of the distributions we support:

Distribution	Llama Stack Docker	Start This Distribution
Meta Reference	llamastack/distribution-meta-reference-gpu	Guide
Meta Reference Quantized	llamastack/distribution-meta-reference-quantized-gpu	Guide
SambaNova	llamastack/distribution-sambanova	Guide
Cerebras	llamastack/distribution-cerebras	Guide
Ollama	llamastack/distribution-ollama	Guide
TGI	llamastack/distribution-tgi	Guide
Together	llamastack/distribution-together	Guide
Fireworks	llamastack/distribution-fireworks	Guide
vLLM	llamastack/distribution-remote-vllm	Guide

Installation

You have two ways to install this repository:

1. Install as a package: You can install the repository directly from PyPI by running the following command:

   pip install llama-stack
   

2. Install from source: If you prefer to install from the source code, make sure you have conda installed. Then, follow these steps:

    mkdir -p ~/local
    cd ~/local
    git clone git@github.com:meta-llama/llama-stack.git
   
    conda create -n stack python=3.10
    conda activate stack
   
    cd llama-stack
    pip install -e .
