Hermes Agent is an open-source autonomous AI agent built by Nous Research and released in February 2026. It's not a coding copilot tethered to an IDE or a chatbot wrapper around a single API. Hermes lives on your server, remembers what it learns, and gets more capable the longer it runs. It supports Linux, macOS, and WSL2 — with no prerequisites, installing everything automatically via a single curl command.
