OpenClaw

API: Anthropic API · OpenAI API

Open or create ~/.openclaw/openclaw.json. The config below sets Imbutus as the provider via the Anthropic API (recommended — native format) and selects the default model:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated"
      }
    }
  },
  "models": {
    "providers": {
      "anthropic": {
        "baseUrl": "https://imbutus.com",
        "apiKey": "<your-api-key>"
      }
    }
  }
}

To use the OpenAI-compatible API instead, define a custom provider with api "openai-completions" and the /v1 base URL:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "imbutus/huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated"
      }
    }
  },
  "models": {
    "mode": "merge",
    "providers": {
      "imbutus": {
        "baseUrl": "https://imbutus.com/v1",
        "apiKey": "<your-api-key>",
        "api": "openai-completions"
      }
    }
  }
}

Available model IDs — replace the primary value with any of these:

huihui-ai/Huihui-Qwythos-9B-Claude-Mythos-5-1M-abliterated
huihui-ai/Huihui-Qwen3.6-35B-A3B-Claude-4.7-Opus-abliterated
imbutus/YuYu1015-Ornith-1.0-35B-abliterated
huihui-ai/Huihui-Qwen3-Coder-Next-abliterated
