Crustoff API

Crustoff is an affordable, OpenAI-compatible API for open-weight generative models. We run the models ourselves on cheap GPUs and pass the savings on — you pay per token for text and per megapixel for images, prepaid, with no subscriptions.

OpenAI-compatible. Point any OpenAI SDK at our base URL and go — no rewrites.
Text and image, one API. Chat, completions and embeddings, plus /v1/images/generations for Stable Diffusion and FLUX.
Open models, fair prices. Transparent per-token and per-megapixel pricing. No lock-in.
