GPT Image 2.5 Sunburst is distinguished by combining image editing with output up to 3,840 × 2,160 pixels. Text and image inputs plus several documented quality levels give the checkpoint room for both new images and controlled changes.

OpenAI lists GPT Image 2 separately, so Sunburst is its own endpoint. OpenAI also exposes a dated September 8, 2026 snapshot alongside the undated model ID.
