OpenAI releases ChatGPT Images 2.5 with a new sketch tool

OpenAI has released ChatGPT Images 2.5, a new version of its image generation model. The company says it produces sharper detail and more natural lighting and textures, and that generation latency is down by as much as 50 percent compared with Images 2.0. Users create more than three billion images a week across ChatGPT Images and the GPT-Image models in the API.

A new Sketch feature, opened by typing "@Sketch" in the chat, takes a rough drawing as the reference for the generated image. Users can leave a comment on a specific area of an image and have only that region changed, and preset templates such as Poster and Merch have been added. Two API models, GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst, are also available. Outputs carry C2PA metadata and invisible watermarks.
