One OpenAI-compatible key for discounted GPT, Claude and Gemini access
The catalogue spans over 90 models across LLMs, image, video, audio and embedding endpoints, individually priced per million tokens.
Each listed provider passes an LLM fingerprint test intended to confirm you receive the exact model you paid for, with no silent substitution.
If a routed channel goes down, requests are automatically routed to the next verified provider, so production calls keep running without manual key rotation.
Use one key and one prepaid balance across every model, with an OpenAI-compatible base URL for tools like Cursor, LangChain and LiteLLM.
Shared GPU cluster for open models, billed at a flat rate instead of per token
Point an existing SDK, agent or coding tool at NaN's endpoint with a personal API key and keep your current code, just swapping the base URL.
Membership plans include recurring credits and the self-hosted models draw none, so heavy experimentation does not scale linearly in cost.
Chat, reasoning and vision models plus embeddings, reranking, Kokoro TTS, Whisper STT and image generation from FLUX and Qwen-Image, all behind one API.
Inference runs in the European Union with zero prompt or response logging; your code is not used for training and only cluster metrics are retained.
