OpenAI's image model comes in two versions on Predis.ai: Flare for fast everyday images, and Sunburst for careful edits where the details have to hold. Both take the same prompt, up to 5 reference photos, and sizes up to 4K.
Luxury fragrance ad photograph. A faceted smoked-glass perfume bottle with a heavy brushed-brass cap stands on a slab of wet black marble. The word NOCTURNE is etched into the glass in thin, widely spaced capitals, and the liquid inside glows deep amber where a single beam of light passes through it. One white moth orchid lies beside the base, and a few drops of water bead on the marble. Low-key studio lighting: a narrow rim light from behind, soft fill from the left, deep shadows, a faint reflection of the bottle in the stone. Shot on a 100mm macro lens, shallow depth of field, rich blacks, warm highlights. No other text.

Product photograph of a compact retro espresso machine in glossy cherry-red enamel with polished chrome trim, a round pressure gauge on the front, two chrome toggle switches and a walnut-handled portafilter locked in place. The name FERRO is embossed in small chrome capitals above the gauge. It sits on a pale terrazzo countertop against a warm off-white plaster wall, with morning light from a window on the left casting a soft, long shadow. Three-quarter front view, 50mm lens, crisp detail, editorial interior styling, generous empty wall space in the upper left. No other text.

Only the jacket changed. Face, pose, board and light came through as they were, which is what makes a reference photo worth adding.

There's no brush. Say where the change goes, such as "the empty wall at the top left", and the model finds it.
Above 2560 × 1440, OpenAI marks output as experimental. Make the image at a smaller size first, then go big on the one you keep.

What is GPT Image 2.5?
It's OpenAI's image model, announced on September 8, 2026, and the one behind ChatGPT Images 2.5. It makes images from text or from up to 5 reference photos, and it edits an image you give it while keeping the rest as it was.
What's the difference between Flare and Sunburst?
They're two versions OpenAI released together. Flare is the fast one for everyday images, and Sunburst is the more capable one for editing and campaign work, where details have to hold. On Predis.ai, Flare usually takes about 25 seconds and Sunburst about 80. Both take the same prompts, sizes and quality settings.
Can GPT Image 2.5 edit my own photos?
Yes. Add your photo as a reference and say what to change, such as a color, a background or a line of text. Everything you don't mention should stay the same, and the edits on this page each started from the one before.
What sizes can it make?
On Predis.ai you can pick from 1024 × 1024 up to 3840 × 2160 (4K), in square, landscape and portrait. OpenAI marks sizes above 2560 × 1440 as experimental, so check those closely.
How is it different from GPT Image 2?
OpenAI says 2.5 is faster and keeps subjects from reference photos more faithfully, and it adds two higher quality settings, xhigh and max. GPT Image 2 is still in the Predis.ai Model Studio if a workflow depends on it.
Can it put text in an image?
Yes, as the headline on the FERRO ad shows. OpenAI still lists text as a known weak spot, so keep headlines short and read every word before you post.
