    Hermes

    AI Agent

    Hermes (also called Hermes Agent) is Nous Research's open-source, self-improving AI agent you can run on desktop, terminal, or cloud. It keeps persistent memory across sessions, builds skills from completed work, and connects to messaging surfaces like Telegram, Discord, Slack, WhatsApp, Signal, and email. Distinct from the Hermes LLM model family name alone.
