Hermes Agent

Hermes Agent is an open-source autonomous agent developed by Nous Research (MIT license). Unlike IDE copilots or chatbot wrappers, it runs persistently on your own infrastructure, learns from every session, and self-improves by generating new skills over time.

🔑 Key capabilities

  • Subagents — isolated subagents with their own conversations, terminals, and Python RPC scripts for parallel, zero-context-cost pipelines
  • Built-in scheduling — natural language cron jobs for reports, backups, and briefings running unattended
