OpenAI releases GPT Image 2.6 Sunburst and Flare in the Image API
OpenAI’s API changelog records the November 4, 2026 release of GPT Image 2.6 Sunburst and Flare. Developers can call both models through the Image API to generate images or edit existing ones.
Sunburst is designed for detailed compositions and editing. Flare is intended for fast iteration, such as trying several visual directions before refining a design.
Both models let developers set how much planning the model does before rendering. The complexity setting has three levels, defaults to high and is separate from rendering quality. Both models also support markup-guided edits, SVG output and animated GIF output.
