Why this API?

Most free AI APIs are throttled, slow, or require signup. We run Qwen3-32B on dedicated Azure A100 GPUs with no login wall. You get instant access — no email, no credit card, no OAuth. Just a key and a curl command.

OpenAI-compatible. Drop it into any tool that speaks OpenAI API format.
