API: Anthropic API · OpenAI API

Open or create ~/.pi/agent/models.json and add Imbutus as a provider. Anthropic API (recommended — Imbutus's native format), with api set to "anthropic-messages":

{
  "providers": {
    "imbutus": {
      "baseUrl": "https://imbutus.com",
      "api": "anthropic-messages",
      "apiKey": "<your-api-key>",
      "compat": {
        "supportsDeveloperRole": false,
        "supportsReasoningEffort": false
      },
      "models": [
        {
          "id": "huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated",
          "name": "huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated",
          "reasoning": true,
          "input": [
            "text",
            "image"
          ],
          "contextWindow": 246416
        },
        {
          "id": "huihui-ai/Huihui-Qwen3.6-35B-A3B-Claude-4.7-Opus-abliterated",
          "name": "huihui-ai/Huihui-Qwen3.6-35B-A3B-Claude-4.7-Opus-abliterated",
          "reasoning": true,
          "input": [
            "text",
            "image"
          ],
          "contextWindow": 246416
        },
        {
          "id": "imbutus/YuYu1015-Ornith-1.0-35B-abliterated",
          "name": "imbutus/YuYu1015-Ornith-1.0-35B-abliterated",
          "reasoning": true,
          "input": [
            "text",
            "image"
          ],
          "contextWindow": 246416
        },
        {
          "id": "huihui-ai/Huihui-Qwen3-Coder-Next-abliterated",
          "name": "huihui-ai/Huihui-Qwen3-Coder-Next-abliterated",
          "reasoning": false,
          "input": [
            "text"
          ],
          "contextWindow": 246416
        }
      ]
    }
  }
}

To use the OpenAI-compatible API instead, set api to "openai-completions" and point baseUrl at the /v1 endpoint:

{
  "providers": {
    "imbutus": {
      "baseUrl": "https://imbutus.com/v1",
      "api": "openai-completions",
      "apiKey": "<your-api-key>",
      "models": [
        {
          "id": "huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated",
          "name": "huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated",
          "reasoning": true,
          "input": [
            "text",
            "image"
          ],
          "contextWindow": 246416
        },
        {
          "id": "huihui-ai/Huihui-Qwen3.6-35B-A3B-Claude-4.7-Opus-abliterated",
          "name": "huihui-ai/Huihui-Qwen3.6-35B-A3B-Claude-4.7-Opus-abliterated",
          "reasoning": true,
          "input": [
            "text",
            "image"
          ],
          "contextWindow": 246416
        },
        {
          "id": "imbutus/YuYu1015-Ornith-1.0-35B-abliterated",
          "name": "imbutus/YuYu1015-Ornith-1.0-35B-abliterated",
          "reasoning": true,
          "input": [
            "text",
            "image"
          ],
          "contextWindow": 246416
        },
        {
          "id": "huihui-ai/Huihui-Qwen3-Coder-Next-abliterated",
          "name": "huihui-ai/Huihui-Qwen3-Coder-Next-abliterated",
          "reasoning": false,
          "input": [
            "text"
          ],
          "contextWindow": 246416
        }
      ]
    }
  }
}

Pi reloads models.json each time you open the /model picker — no restart needed.

You can find your API key on the profile page.
