Llama Stack Review 2026

Llama Stack: Meta's standardized API and toolchain for building AI agents with Llama models, providing inference, safety, memory, and tool use in a unified stack.

Llama Stack is Meta's open-source toolchain and standardized API for building AI applications and agents using Llama models. It provides a unified interface that standardizes the core building blocks of agent development — inference, safety, memory, tool use, and evaluation — into a consistent API that works across different deployment environments from local development to cloud production.

The stack is designed around a distribution model where different providers implement the standardized APIs. A local development distribution might use Ollama for inference and ChromaDB for memory, while a production distribution could use AWS Bedrock for inference and PostgreSQL for persistence. The API remains the same, making it easy to develop locally and deploy to production without code changes.
