Overview

Llama Stack defines and standardizes the core building blocks that simplify AI application development. It provides a unified set of APIs with implementations from leading service providers. More specifically, it provides:

• Unified API layer for Inference, RAG, Agents, Tools, Safety, Evals.
• Plugin architecture to support the rich ecosystem of different API implementations in various environments, including 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

• Flexibility: Developers can choose their preferred infrastructure without changing APIs and enjoy flexible deployment choices.
• 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 integrated with distribution partners (cloud providers, hardware vendors, and AI-focused companies) that offer tailored infrastructure, software, and services for deploying Llama models.

For more information, see the Benefits of Llama Stack documentation.

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. For example, you can begin with a local setup of Ollama and seamlessly transition to production, with fireworks, without changing your application code. Here are some of the distributions we support:

Distribution	Llama Stack Docker	Start This Distribution
Starter Distribution	llamastack/distribution-starter	Guide
Meta Reference	llamastack/distribution-meta-reference-gpu	Guide
PostgreSQL	llamastack/distribution-postgres-demo

For full documentation on the Llama Stack distributions see the Distributions Overview page.
