      description: 'OpenAI GPT-Image-2 — next-generation image model with significantly improved text rendering. Text-to-image and image editing with up to 9 reference images, 1K/2K/4K output, and three quality levels. Billing: per image, resolution × quality — medium quality bills 60/120/180 credits at 1K/2K/4K, low bills half that (30/60/90), high bills 250/500/750.


        **Asynchronous.** Returns a job `id` (the image is not in this response). Poll [`GET /v1/images/{id}`](/api-reference/images/get-image-job-status) until `status` is `succeeded` — the generated image URLs are in that response''s `images` array (each `{ url, position }`).'
