ChatGPT Images 2.5 enhances localized editing and multi-turn consistency, and OpenAI has also added features like Sketch, templates, and image comments. You can use an existing image for small-scale testing. Clearly specify the only object that needs to be modified in the prompt, while listing the character traits, composition, text, and brand elements that must be preserved. Make only one change per round, then check the target modification and other areas after generation. If you notice any drift, revert to the last qualified version and continue. Images 2.5 is being rolled out gradually, and the availability of features may vary across different accounts and platforms.
