The self-improving AI agent built by Nous Research. The only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, and builds a deepening model of who you are across sessions.
Install
Windows or macOS
To easily install the command-line and desktop applications, download the Hermes Desktop installer from our website and run it.
Without Hermes Desktop:
For a command-line only install without Hermes Desktop, run:
Linux / macOS / WSL2 / Android (Termux)
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
Windows (native)
Run in powershell:
iex (irm https://hermes-agent.nousresearch.com/install.ps1)
See the full Installation Guide for what the installer does, the per-user vs root layout, and Windows-specific notes. For the complete platform support matrix, see Platform Support.
After installing, run hermes setup --portal — one OAuth covers a model plus all four Tool Gateway tools (web search, image generation, TTS, browser). See Nous Portal.
What is Hermes Agent?
It's not a coding copilot tethered to an IDE or a chatbot wrapper around a single API. It's an autonomous agent that gets more capable the longer it runs. It lives wherever you put it — a $5 VPS, a GPU cluster, or serverless infrastructure (Daytona, Modal) that costs nearly nothing when idle. Talk to it from Telegram while it works on a cloud VM you never SSH into yourself. It's not tied to your laptop.
