Hermes Agent is an open-source AI agent built by Nous Research with 23,600+ GitHub stars. What makes it unique? It learns from experience.
The Learning Loop
Most agents do what you tell them and forget everything. Hermes:
- 1.Solves a task using tools (terminal, browser, file editing)
- 2.Saves what it learned to persistent MEMORY.md
- 3.Creates a reusable skill if the task was complex
- 4.Improves the skill next time it's used and hits an error
This is the closed learning loop — the defining feature of Hermes. No other agent does this.
