Open-source self-improving AI agent framework by Nous Research with persistent memory, 40+ tools, and 135K+ GitHub stars.
Hermes Agent is an open-source autonomous AI agent framework developed by Nous Research that has become the fastest-growing open-source AI agent project of 2026, accumulating over 135,000 GitHub stars in under three months since its February 2026 release. What makes Hermes Agent fundamentally different from other agent frameworks is its built-in learning loop: the agent creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who the user is across sessions.
The framework is entirely self-hostable — it can run on a $5/month VPS — and ships with 40+ built-in tools covering file management, web browsing, code execution, and more. The memory system is Hermes Agent's most distinctive feature: rather than treating each conversation as isolated, the agent learns from its own mistakes and successes across sessions, building persistent knowledge that makes it genuinely more useful over time. This creates a fundamentally different user experience from stateless chatbots.
