What Is Hermes Agent?
Developed by Nous Research and crossing 140,000 GitHub stars in early 2026, Hermes Agent is the premier open-source autonomous agent designed to grow alongside you. Unlike thin wrappers around LLM APIs, Hermes features a closed learning loop: it creates skills from experience, improves them during use, and builds a deepening model of the user via FTS5 cross-session recall.
What makes Hermes Agent unique?
Hermes Agent stands out with its closed-loop self-improvement system where the agent writes, refinement-tests, and saves its own tools, creating a highly customized development environment over time.
Hermes Agent Key Features
Self-Evolving Skills
Automatically writes, refines, and persists its own reusable tools and scripts.
