ChatGPT Images 2.5 combines a redesigned ChatGPT image workflow with two developer models. Flare prioritizes speed for everyday generation, while Sunburst is positioned for more precise generation and editing. The feature set is promising, but a final winner between the two models requires matched prompts, repeated latency runs, and controlled edit comparisons.<\/p>\n\n\n\n Plate-forme d'IA tout-en-un pour l'\u00e9criture, la g\u00e9n\u00e9ration d'images et de vid\u00e9os avec GPT-5, Nano Banana, etc.<\/strong><\/p>\n\n\n\n ChatGPT Images 2.5 is the image-generation and editing update OpenAI announced on September 8, 2026. It is available through the ChatGPT experience, while developers get two related API models named GPT-Image-2.5 Flare and GPT-Image-2.5 Sunburst. That product-versus-model distinction matters because the ChatGPT interface and the API expose different controls and workflows.<\/p>\n\n\n\n OpenAI says people create more than 3 billion images per week across ChatGPT Images and its GPT-Image API models. The company also claims up to 50% lower generation latency than Images 2.0, alongside improvements to reference fidelity, targeted editing, multi-turn consistency, lighting, texture, layouts, and transparent backgrounds. These are official launch claims, not independent benchmark results.<\/p>\n\n\n\n If you need a broader explanation of the product family, the guide to the best ChatGPT model for image generation<\/a> helps separate ChatGPT product features from individual model names. The simpler ChatGPT image-generation guide<\/a> covers the basic creation workflow.<\/p>\n\n\n\n The most visible improvements are not hidden in an API parameter. They sit directly in the ChatGPT image workflow and are meant to reduce the amount of prompt rewriting required between an idea and a usable asset.<\/p>\n\n\n\n Sketch lets you draw a rough composition directly in ChatGPT and use it as a visual reference. That can be more efficient than describing spatial relationships in a long prompt, especially when the position of a subject, title area, or background element matters more than artistic detail.<\/p>\n\n\n\n The real value will depend on how faithfully Images 2.5 follows a rough layout without treating every line as literal content. A useful test should compare the sketch, the requested hierarchy, and the final composition rather than judging only whether the output looks polished.<\/p>\n\n\n\n Templates provide structured starting points for common formats such as product photos and flyers. They can help occasional users avoid blank-page prompting, but experienced creators will care about whether the template exposes enough control over text, layout, aspect ratio, and reference preservation.<\/p>\n\n\n\n Images 2.5 allows users to place comments on an image and request a focused change. This is one of the update’s most practical ideas because it turns editing into a location-aware conversation. It should reduce ambiguity when a prompt such as \u201cchange the label\u201d could otherwise affect the bottle, background, lighting, or typography.<\/p>\n\n\n\n Comment placement does not by itself prove that unchanged regions remain identical. The important measurement is whether the requested region changes successfully while the rest of the image stays stable. The existing guide to how ChatGPT edits images<\/a> explains the broader editing workflow.<\/p>\n\n\n\n The updated editor also brings common finishing actions closer to the generated image. Remove BG and Resize can save a trip to another tool when the output only needs basic adaptation. Version history matters during multi-step editing because users need a reliable way to return to a stronger earlier result when a later instruction introduces drift.<\/p>\n\n\n\n![\"Accueil](\"https:\/\/wp.glbgpt.com\/wp-content\/uploads\/2025\/09\/\u622a\u5c4f2025-12-24-15.22.51-1024x422.webp\")
