## In short

Open GenAI Stack adds /v1/messages passthrough for Anthropic APIs, Google Interactions API frontend for Gemini, raises OpenAI API conformance from 89.1% to 91.2%, and adds conversation compaction for long agent sessions.

## What it is

Llama Stack is Meta's open-source, unified deployment stack for Llama-family models and an expanding set of third-party models. Version 0.8.0 landed May 1, 2026, adding multi-provider API compatibility as a core focus.

## How it works

The v0.8.0 release implements the /v1/messages endpoint in both passthrough mode (forwarding to Anthropic directly) and translation mode (converting Anthropic-format requests to Llama Stack internals). The Google Interactions API frontend provides a similar bridge for Gemini. The OpenAI API conformance suite now covers 91.2% of the spec. Conversation compaction automatically summarizes old context in long Responses API sessions to keep agents within context limits.

## Why it matters

By natively supporting Anthropic, Gemini, and OpenAI API formats, Llama Stack is moving from a Llama-specific tool to a universal GenAI interface that lets teams switch providers without rewriting application code.

## Who it's for

Enterprise teams wanting a provider-agnostic deployment layer for LLMs, especially those running on-premise Llama models alongside cloud-hosted Claude or Gemini.

## Try it

pip install llama-stack==0.8.0
