Using Roo Code with NanoGPT

Setup Instructions

  1. Get your API key from nano-gpt.com/api

Tip: Roo Code surfaces the thinking and response channels side-by-side. Pointing it at https://api.nano-gpt.com/api/v1thinking/ keeps that richer reasoning stream intact for models like Minimax M2 or Kimi K2 Thinking.
That’s it! You can now use Roo Code with every model you can think of. Model names are on our pricing page - important ones are openai/gpt-6.1-sol, anthropic/claude-opus-5.5, google/gemini-flash-latest, or just any other model you fancy.
