Wait, which Hermes do you mean?

Nous Research ships three things under the Hermes name: an open-weight model family, a free autonomous-agent framework, and a paid hosted subscription. Confusing them leads to pricing the wrong thing.

In this lesson you will

  • Name the three products Nous Research ships under "Hermes"
  • Say which of the three is free and which is a paid subscription
  • Know what Hermes Agent is a direct successor to

Nous Research is an open-source AI lab, and "Hermes" is the name it's reused across three distinct things. Mixing them up is the single most common way to misread a Hermes price — a free open-weight model and a $200/month subscription share the same first word.

Three products, one name.
NameWhat it isHow it's priced
Hermes (the model)An open-weight LLM family, currently Hermes 4, that anyone can download, self-host, or access through a cloud APIFree to download; per-token if you access it through a hosted API
Hermes AgentA free, open-source, self-hosted autonomous agent framework — the direct successor to OpenClaw, with persistent memory and a self-improving learning loopFree software; you supply the model behind it
Nous PortalNous Research's own hosted subscription service: access to 248 models via OpenRouter, a bundled tool gateway, and managed Hermes Cloud hostingPaid subscription tiers

The rest of this course prices each piece in turn: the model itself in lesson 2, then Hermes Agent's own setup in lesson 3.
