GPT Image 2.6 Sunburst is the more capable of OpenAI's two November 2026 image tiers, built for long chains of edits where a character, product or layout must not drift. It is slower than GPT Image 2.6 but takes the same inputs: prompt, up to 16 reference images, quality up to max, complexity, and animated GIF output (2-16 frames).
Best for
- A series of images with the same character or product in different scenes
- Iterating on one ad creative without details drifting
- Animated GIFs where detail precision matters
FAQ

Sunburst or regular GPT Image 2.6?
Use GPT Image 2.6 for single images and quick variants; pick Sunburst for long edit chains where details must stay put.
