Simon Willison tests reference-image editing with ChatGPT Images 2.5
Simon Willison's September 8 note documents an update to his image-generation tool for the new Sunburst and Flare models, including support for reference images. He demonstrates an edit that adds a subject to an existing image. The linked release positions Sunburst for editing precision and Flare for faster everyday work. This is a limited practitioner example, not a comparative benchmark or independent validation of every claimed improvement in the model family.
