LiteLLM Integration

Configure LiteLLM to proxy requests through NanoGPT while preserving the legacy reasoning_content field expected by its OpenAI-compatible connector.

Quick configuration

Add NanoGPT to your litellm.yaml (or the equivalent configuration source):

model_list:
  - model_name: nano-gpt
    litellm_params:
      model: openai/gpt-5.6-sol
      api_base: https://nano-gpt.com/api/v1legacy/
      api_key: ${NANO_GPT_API_KEY}

Set your API key before launching LiteLLM:

export NANO_GPT_API_KEY='your-api-key-here'
litellm --config litellm.yaml

LiteLLM’s OpenAI adapter expects streaming deltas in delta.reasoning_content, so the v1legacy endpoint is the recommended base URL. If you upgrade your LiteLLM deployment to parse the modern delta.reasoning field, you can switch the base URL to https://nano-gpt.com/api/v1/ instead. You can also swap model to anthropic/claude-opus-4.5 or google/gemini-3-flash-preview if you want a different default.
