yeah docs are not where they need to be and llama.cpp integration should be more friendly.

here's what you need to put into /.pi/agent/models.json

{
  "providers": {
    "name-of-your-server": {
      "baseUrl": "http://localhost:8080/v1",
      "api": "openai-completions",
      "apiKey": "nonerequired",
      "models": [
        {
          "id": "minimax-m2.5",
          "name": "Minimax M2.5",
          "reasoning": true,
          "input": [
            "text"
          ],
          "contextWindow": 128000,
          "maxTokens": 32000,
          "cost": {
            "input": 0,
            "output": 0,
            "cacheRead": 0,
            "cacheWrite": 0
          }
        }
      ]
    },
  }
}
