# Afnio

> The framework for building and auto-optimizing the agent harness and context.

Afnio is an open-source Python SDK that auto-optimizes AI agent harness and context — define your harness, call `optimizer.step()`, and let Afnio do the rest. Hit production accuracy requirements in minutes, not months. The Afnio SDK is open source; running it requires a Tellurio API key (free tier available).
