What is GPT Image 2.5 Sunburst Edit?
GPT Image 2.5 Sunburst Edit is one of the two models OpenAI shipped with ChatGPT Images 2.5 on 2026-09-08. Sunburst is the more literal of the pair — in our first side-by-side it rendered a broader, more documentary view of the scene with flatter lighting. It keeps the 2.x strengths — strong text rendering, neutral colour, high prompt adherence — and adds a wider quality ladder plus materially faster generation. The headline change is the quality ladder: 2.5 exposes five paid tiers (low, medium, high, xhigh, max) where earlier GPT Image models exposed three. The tiers were also re-spread, so a 2.5 tier name does NOT correspond to the same-named tier on GPT Image 2 — pick a tier by its price and output, not by its label. Requests run against OpenAI directly, with fal.ai wired as a same-model fallback so a provider outage reroutes without changing the model.
