Use crazyrouter-hermes to point Hermes Agent at Crazyrouter. After setup, Hermes uses https://crazyrouter.com/v1 as its OpenAI-compatible endpoint and calls Claude, GPT, DeepSeek, Gemini, Qwen, and 627+ other models through a single Crazyrouter API key.

​
Best For

  • Hermes Agent users who want to use Crazyrouter as the model provider
  • local agent workflows that should share Crazyrouter models and quota
  • users who want a one-command setup for OPENAI_API_KEY, OPENAI_BASE_URL, and the default model

​
Prerequisites

ItemNotes
Hermes AgentInstall Hermes locally and confirm it can start
Crazyrouter accountCreate one at crazyrouter.com
Crazyrouter API keyCreate a dedicated sk-... token for Hermes
Model accessAllow the models you plan to use in that token
Hermes connects to Crazyrouter through OpenAI-compatible settings. Keep the base URL as https://crazyrouter.com/v1.

​
One-Click Setup

curl -fsSL https://raw.githubusercontent.com/xujfcn/crazyrouter-hermes/main/setup.sh | bash
The script prompts for your Crazyrouter API key, lets you choose a default model, and can optionally test the connection.
The setup script writes local Hermes config. Back up ~/.hermes/.env and ~/.hermes/config.yaml first if you already have custom settings.

​
Manual Setup

If you prefer not to run the script, write the Hermes config manually.

​
Environment Variables

Edit ~/.hermes/.env: 
OPENAI_API_KEY=sk-your-crazyrouter-key
OPENAI_BASE_URL=https://crazyrouter.com/v1

​
Default Model

Edit ~/.hermes/config.yaml: 
model:
  provider: "custom"
  default: "claude-opus-4-7"
  base_url: "https://crazyrouter.com/v1"
Change default to any model allowed by your Crazyrouter token.

​
Switch Models

After setup, switch models inside Hermes with /model: 
/model claude-opus-4-7
/model gpt-5.4
/model claude-sonnet-4.6
/model gemini-3-pro
/model deepseek-chat
/model qwen-max
/model gpt-4o
If switching returns model not allowed or 403, the current Crazyrouter token usually does not allow that model.

​
Verification Checklist

  • OPENAI_API_KEY in ~/.hermes/.env is a valid Crazyrouter token
  • OPENAI_BASE_URL is https://crazyrouter.com/v1
  • provider in ~/.hermes/config.yaml is custom
  • the default model is allowed by the Crazyrouter token
  • Hermes can return a test response
  • /model gpt-5.4 or another allowed model switches successfully
