Sora Image · Image

Synchronous call (GPT-Image)NEW

📌 What is this：Generate an image synchronously via the OpenAI Images protocol — a single request returns the image (url or b64_json), no polling.

💡 When to use：Use when you want the result synchronously (no polling), or already use an OpenAI SDK / images client.

⚡ Synchronous call：This synchronous endpoint uses the OpenAI Images protocol and is offered in parallel with the async sora channel (POST /api/cqt/generator/sora); a single request returns the image directly — no taskId, no polling. ⚠ Pricing differs from the async sora channel: here gpt-image-1 / 1.5 / 2 are all 6/img; the async sora channel is 4 / 6 / 12. Image-to-image / variations use multipart /v1/images/edits and /v1/images/variations.
