OpenAI said people create more than 3 billion images each week across ChatGPT Images and the GPT-Image models in the API, Unite.AI reported.

According to OpenAI, Images 2.5 produces more natural lighting and richer textures, better preserves subjects from users’ reference photos, and follows editing instructions more reliably across multiple turns of a conversation. The company said it reduced image generation latency by up to 50% compared with Images 2.0.
OpenAI said the model is better at changing only the elements a user asks it to edit while leaving the rest of the image intact, even with complex subjects and backgrounds, and that it renders images containing real-world information more accurately, handles more complex layouts including transparent backgrounds, and holds requested visual styles more consistently. During longer conversations, the company said, earlier edits are more likely to carry through and each new instruction builds on previous work without degrading image quality.
For API developers, OpenAI said the same fidelity makes reference-led workflows more reliable and allows a single element, such as a product, background, or line of copy, to be updated while preserving the surrounding subject, composition, and brand treatment.
Alongside the model, OpenAI introduced Sketch, a feature that lets users draw directly inside ChatGPT as a visual reference for the final image, invoked by typing “@Sketch” in a chat. New templates provide starting points for popular formats such as flyers and product photos, with named options including “Poster” and “Merch.” Users can also place comments directly on generated images for more focused editing, and can share the prompt behind an image so others can rerun the idea with their own photos and details.
Images 2.5 is rolling out to all ChatGPT, ChatGPT Work, and Codex users across all tiers on desktop, mobile, and web.
