Open-weight models ship with published weights and permissive licenses, so you can inspect them, self-host them, and avoid lock-in to a closed vendor. ZeroGPU serves eight of them — for reasoning, coding, agentic workflows, high-volume summarization, and safety classification — through the same OpenAI-compatible API as every other model in the catalog. Full request and response examples live on the Text Generation page.
