NanoGPT
One OpenAI-compatible API routing to 900+ models across 40+ providers.
About
NanoGPT is an inference platform and multi-model router that aggregates hundreds of models from 40+ providers behind a single OpenAI-compatible API at nano-gpt.com. Developers point their existing OpenAI client code at a new base URL, set a NANOGPT_API_KEY, and get live model discovery plus per-token pricing across text, image, video, and 3D models.
It is frequently cited in 2026 comparisons as an OpenRouter alternative, positioned around wide model coverage and pay-as-you-go pricing without markup. Third-party tooling increasingly ships native NanoGPT provider support with live pricing pickers.
