Quick Setup Guide

  1. Install OpenClaw (ClawdBot) and skip any default model setup.
  2. Get your API key from nano-gpt.com/api.
  3. Open your config (Config -> Models -> Raw, or edit ~/.clawdbot/clawdbot.json).
  4. Add a NanoGPT provider block like this:
{
  "models": {
    "mode": "merge",
    "providers": {
      "nanogpt": {
        "baseUrl": "https://nano-gpt.com/api/v1",
        "apiKey": "YOUR_NANOGPT_API_KEY_HERE",
        "auth": "api-key",
        "api": "openai-completions",
        "headers": {},
        "authHeader": false,
        "models": [
          {
            "id": "anthropic/claude-opus-4.5",
            "name": "Claude Opus 4.5",
            "reasoning": false,
            "input": ["text"],
            "cost": {
              "input": 0,
              "output": 0,
              "cacheRead": 0,
              "cacheWrite": 0
            },
            "contextWindow": 200000,
            "maxTokens": 8192
          }
        ]
      }
    }
  }
}
  1. Replace YOUR_NANOGPT_API_KEY_HERE with your actual key.
  2. Restart OpenClaw (or restart the gateway if you are using it).
