Image generation powered by OpenAI's gpt-image-2 (GPT Image 2), the upgrade to gpt-image-1 with sharper detail, better composition and stronger prompt adherence. Describe the picture you want in a few sentences and receive a high-resolution illustration or photo-style output. Style, aspect ratio, and subject are all controllable via prompt. You can also upload a picture and edit it with plain-language instructions such as "replace the background with a city at night" or "change the jacket to red"; if the result is not quite right, just send another instruction and the previous output is reused for continuous refinement. Great for marketing banners, slides, blog headers, and product concept art.
