We're excited to share that Llama Stack has achieved 100% compliance with the Open Responses specification and been officially recognized as part of the Open Responses community. This milestone represents more than just compatibility: it's about bringing enterprise-grade AI capabilities to your own infrastructure with the familiarity of OpenAI APIs.

With comprehensive support for Files, Vector Stores, Search, Conversations, Prompts, Chat Completions, the full Responses API, plus powerful extensions like MCP tool integration, Tool Calling, and Connectors, Llama Stack offers something unique in the AI infrastructure landscape: a SaaS-like experience that runs entirely on your terms.

The Responses API is rapidly emerging as one of the most influential interfaces for building AI agents. It handles multi-step reasoning, tool orchestration, and conversational state in a single interaction, which is a big improvement over the manual orchestration loops that developers had to build on top of chat completion APIs. Llama Stack's implementation of the Responses API brings these capabilities to the open source world, where you can choose your own models and run on your own infrastructure.

This post covers why the Responses API matters, what Llama Stack's implementation enables, and how it connects to the broader move toward open agent standards like Open Responses.
