Using OpenHands with NanoGPT

A quick guide to setting up OpenHands with NanoGPT’s API.

​
Setup Instructions

  1. Get your API key from nano-gpt.com/api
  2. In OpenHands, add a new LLM Endpoint and toggle “Advanced”.
  3. Configure the fields as follows:
    • Custom Model: openai/<MODEL_NAME_FROM_NANOGPT>
      • Example: openai/openai/gpt-5.2
      • If a model name contains a slash, include it: e.g. openai/anthropic/claude-opus-4.5 or openai/google/gemini-3-flash-preview
    • Base URL: https://nano-gpt.com/api/v1 (no trailing slash)
    • API Key: Your key from step 1
    • Search API Key (Tavily): Optional
    • Agent: CodeActAgent (recommended)

​
Important Notes

  • The Base URL must NOT end with a /. Use https://nano-gpt.com/api/v1 exactly.
  • Prefix the model with openai/ and use the exact model name as shown by the NanoGPT API or on our pricing page.
You can now use OpenHands with any NanoGPT model. Popular choices include openai/gpt-5.2, anthropic/claude-opus-4.5, and google/gemini-3-flash-preview. For a full list, check our pricing page.
