GPT Image 2.5 is OpenAI's image model for generating and editing images, available on Leonardo.Ai in two versions, GPT Image 2.5 Flare and GPT Image 2.5 Sunburst. You can add up to 16 image references, make up to 8 images at once and choose from 10 aspect ratios.
Both have the same controls and the same cost on Leonardo.Ai. Choose Flare for fast, everyday work with strong prompt following. Choose Sunburst when fine line work and small labels must hold up to a close look, and for precise edits.
Yes. Add your photo as an image reference and describe the change, for example a new label, a new background or a new line of text. GPT Image 2.5 keeps the rest of the picture. For more ways to edit, see the AI image editor.
Yes. Turn on the transparency option in the advanced settings, and GPT Image 2.5 makes a PNG with a transparent background. Leave the option off to get a JPEG. See the transparent PNG generator for more.
The generation panel shows the exact token cost before you generate. The cost depends on the image size, the quality, the number of images and the number of image references. Flare and Sunburst cost the same.
Yes. Both versions are in the Leonardo API. The API docs for GPT Image 2.5 Sunburst and GPT Image 2.5 Flare have the request format and parameters.
GPT Image 2.5 takes up to 16 image references, against 6 for GPT Image 2. It has two more quality levels, Extra High and Max, and it can make transparent PNGs.
Yes. Use each result as the image reference for your next edit, and describe the next change. Repeat the details you want to keep in each prompt, so they stay the same.
