Hermes Agent Cloud

Hermes Agent Cloud deploys Hermes Agent as a RailPush service with a RailPush guest chat URL.

Defaults​

  • Runtime image: pinned RailPush Hermes image
  • Port: 8642
  • Health check: /health
  • Provider: openai-codex
  • Model: gpt-5.1
  • API server: OpenAI-compatible /v1/chat/completions

Authentication​

After creating the instance, use the ChatGPT sign-in panel in RailPush. Hermes starts its device-code OAuth flow, RailPush shows the authorization URL and code, and the user confirms when browser sign-in is complete.

No OpenAI API key is required for this path.
