Raven: Open-Source Multi-Agent Ecosystem That Auto-Builds and Evolves Harnesses of Harnesses

EverMindAI · hf · 2026-09-30

Raven, an open-source multi-agent ecosystem from EverMindAI, treats each executable model–harness pair as a composable unit of intelligence. A Host Agent decomposes goals, matches subtasks to specialized agents, and coordinates execution; a host archive and EverOS preserve experience across tasks while Skill Forge turns it into reusable procedures. The paper establishes sufficient conditions for such composition to expand reliable task coverage, and Raven significantly outperforms state-of-the-art agent systems on complex long-horizon tasks.
