Pi

Pi reads custom OpenAI-compatible providers from ~/.pi/agent/models.json. Register AnyRouter once to run Pi on any AnyRouter model with one sk-ar- key.

Fastest path

curl -fsSL https://anyrouter.dev/cli.sh | bash
anyr pi

The launcher writes a Pi agent dir (PI_CODING_AGENT_DIR) with AnyRouter in models.json, sets ANYROUTER_API_KEY, and starts pi --provider anyrouter. Use anyr pi --install --ok to install Pi too. Pi has no MCP support, so Auto-connect does not apply.

Manual setup

1. Create a key in the dashboard and export it (add to ~/.zshrc or ~/.bashrc to persist):

   export ANYROUTER_API_KEY="sk-ar-your-anyrouter-key"

2. Add AnyRouter to ~/.pi/agent/models.json:

   {
     "providers": {
       "anyrouter": {
         "baseUrl": "https://anyrouter.dev/api/v1",
         "api": "openai-completions",
         "apiKey": "ANYROUTER_API_KEY",
         "models": [
           { "id": "openai/gpt-5.4-mini" },
           { "id": "anthropic/claude-sonnet-4-6" }
         ]
       }
     }
   }

   apiKey is the environment variable name, not the secret. Do not paste your sk-ar- key here.

3. Run Pi:

   pi --provider anyrouter --model "openai/gpt-5.4-mini"

Add more models from the catalog as entries in models, with the id exactly as listed (for example google/gemini-3.1-flash-lite). The call appears in your request logs.
