Meet GPT Image 2.5 Sunburst
GPT Image 2.5 Sunburst is the most detailed image model in Advibly. It follows long, instruction-heavy prompts closely, renders text cleanly, and edits reference images without disturbing what you asked it to keep.
It takes up to 16 reference images and offers five quality tiers, from Low for drafts to Max for the final asset. It is slower than Flare, and worth the wait for a hero image.
