Create a response

Creates a model response using the Responses API. Supports streaming (stream: true, server-sent events) and background mode (background: true). When streaming, each frame carries a named event: and a JSON data: payload, and the stream ends on a terminal event, one of response.completed, response.failed or response.incomplete; there is no [DONE] sentinel. OpenAI-compatible, so existing Responses API code runs unmodified.
