Hermes Agent

Hermes Agent is an AI agent that “evolves on its own” introduced by Nous Research. After being made open source in February 2026, it grew at an astonishing rate, surpassing 47,000 stars in less than two months. Its key innovation lies in automatically abstracting experience into reusable Skill files after completing tasks, eliminating the need for re-inference during subsequent executions—making it smarter with each use. It features a three-tier persistent memory system that supports a self-training loop. With an average daily token consumption of 458B, it has already surpassed OpenClaw. The community generally views Hermes Agent as a “thinking brain,” suitable for automation scenarios that require long-term experience accumulation and continuous improvement.
