GPT Image 2.5 Sunburst is OpenAI's most capable image model. It generates images from text and edits images you give it with precise, instruction-following control, and it is tuned for the workflows where editing precision matters most: the change you asked for happens, and the parts you did not mention stay as they were.
On this page you can use GPT Image 2.5 Sunburst free, with no sign up, no OpenAI account and no API key. AI Free Forever runs the same model OpenAI serves through its API and puts it behind the prompt box at the top of the page. Type what you want, attach a photo if you are editing, pick a size, and download the result.
Sunburst handles two workflows. Generating: describe a scene and get an image. Editing: pass one reference image to change it, or several to combine subjects, styles and references into a single output. Reference images are processed at high fidelity automatically, so a face, a product or a room comes back recognisable. Sunburst is the model to insert a person into a new scene while preserving their likeness, or to swap the furniture in a room photo without moving the camera.
Precise Editing
Targeted changes without reinterpreting the whole image. Identity, composition and lighting are preserved
Photorealism
Accurate lighting, believable materials and rich textures that read as photography
Text Rendering
Dense text, small lettering and complex layouts such as infographics, UI mockups and marketing material
Transparent Backgrounds
A background input with auto, transparent and opaque, for cutouts and product shots
Sunburst also carries style control: apply one consistent look across different subjects, or transfer the style of one image onto another with minimal prompting. For illustrated work it keeps a character the same from page to page, which is what makes a multi-page comic possible in one sitting.
GPT Image 2.5 Sunburst is free on aifreeforever.com with no account, no API key and no credit card. The prompt box is at the top of this page.
Write a Prompt
For a new image, describe subject, setting, lighting, lens and framing. For an edit, say exactly what should change and what must stay the same.
Add Reference Images (optional)
Attach one image to edit it, or up to three to combine subjects, styles or references into one result.
Pick Size, Format and Background
Choose from seven aspect ratios, WebP, PNG or JPG, and a normal or transparent background. Transparent selects PNG for you.
Download
Save the image with no watermark. Commercial use is allowed subject to OpenAI's usage policies.
OpenAI released two GPT Image 2.5 models together. Sunburst is the most capable one, for precision. GPT Image 2.5 Flare is the fast one, for everyday generation at volume. Both are free on AI Free Forever, so the choice is about the job, not the price.
