  version: v1
  description: OpenAI-compatible inference API for Gradient Cloud — the enterprise inference service of Gradient's Open Intelligence Stack, serving open models across a distributed compute network (Parallax) over Gradient's peer-to-peer data motion engine (Lattica). The API implements OpenAI-compatible interfaces for model listing, chat completion, and text completion (streaming and non-streaming). Generated by the API Evangelist enrichment pipeline from the provider's published API Reference Documentation; not an official provider OpenAPI. Verify against the live docs before production use.
