ChatGPT Images 2.5 fixes the two things that most annoyed people about AI images: waiting, and edits that wreck the rest of the picture. It comes in two versions. Flare is the fast everyday default, with better quality than Images 2.0 at about half the wait. Sunburst takes longer but keeps faces, products, and lighting consistent across round after round of changes.
Flare delivers higher quality than GPT Image 2 at roughly 50% lower latency, according to OpenAI. Sunburst adds sharper detail, more natural lighting, and tighter consistency across edits. Carries forward Images 2.0's reliable text rendering. Transparent backgrounds on demand, and the @Sketch tool in ChatGPT lets you steer layout with a rough drawing.
Sunburst is slower and heavy editing sessions eat into paid plan or API budgets. OpenAI's safety filters remain among the strictest, so edgy or dark concepts can be refused. For painterly, atmospheric art, Midjourney still has the more natural artistic touch.
