Summary
OpenAI said GPT-Images-2.5 is now live for all ChatGPT, ChatGPT Work and Codex users — including the free tier — with image generation latency reduced by up to 50%.
The upgrade focuses on tighter editing control: users can change only selected regions, preserve composition and subjects across repeated edits, and mark areas directly on images for revision.
Four product additions broaden input beyond text, including Sketch for hand-drawn prompts, templates for posters and product images, and prompt sharing for reusable styles.
For developers, OpenAI split its image API for the first time into Flare for faster, high-volume generation and Sunburst for slower, higher-precision creative work; Adobe said it is integrating the model into Firefly.
OpenAI said ChatGPT Images and the GPT-Image API now process 3 billion images a week, underscoring how central image generation has become to its broader multimodal push.
