OpenAI's ChatGPT Images 2.5 cuts latency by up to half and tops the image leaderboard

OpenAI has upgraded its image generator to ChatGPT Images 2.5, promising sharper detail and better retention of subjects from reference photos. Latency falls up to 50% versus the previous version, and users can now steer edits with sketches or by pointing at a region. Two API variants ship: Sunburst for editing precision, Flare for speed. OpenAI holds the top three spots on Arena AI's text-to-image leaderboard.
