Guides
About GPT-Image-2.5 Sunburst
GPT-Image-2.5 Sunburst generates and edits images from text and image inputs and is positioned by OpenAI for workflows where editing precision matters most. It supports quality settings low, medium, high, xhigh, max and auto, and the image generation, image edit (including inpainting) and Batch endpoints. It can be selected directly in the Image API or as the model of the image generation tool in the Responses API. The default snapshot is gpt-image-2.5-sunburst-2026-09-08.
Strengths and weaknesses
Strengths
- Text and image input with image generation, editing and inpainting
- Quality settings
xhighandmaxin addition to low, medium, high and auto - Custom sizes with edges up to 3840 px and up to 8,294,400 total pixels (resolutions above 2560x1440 are experimental)
- Batch API pricing at 50% of the Standard token rates
Weaknesses
- Takes longer to generate than GPT-Image-2.5 Flare, according to OpenAI's announcement
- Billed per token with no published per-image price; the image generation guide notes that token consumption differs by model and quality setting
- Cached input rates apply only to the Responses API image generation tool, not to direct Image API requests
