gptimage25.top is an independent, third-party browser interface for OpenAI's GPT Image 2.5, which OpenAI released on 8 September 2026 as two separate API models. Both of them are selectable here on one toggle: gpt-image-2.5-flare for speed, gpt-image-2.5-sunburst for the quality ceiling. Inside ChatGPT you can pick neither, and you are not told which one answered.

So the first thing the site does is print the answer. Under every result there is a receipt — the model ID the API returned, the quality tier, the pixel size, the format and the elapsed time, with the raw API response one click away.

The second thing is editing that does not chain. Chat editors re-edit their own last output, which is why quality collapses by the third pass. Here every edit is recomputed from the file you uploaded, and five Keep-Intact checkboxes — face and identity, camera angle, text and labels, lighting, product shape — assemble OpenAI's recommended "change only X" phrasing for you. Nothing is ever overwritten: each generation and edit is a version you can branch from.

There are six quality tiers, native 4K at 3840×2160, validated custom sizes, a prompt library with every prompt printed beside the image it produced and the settings it ran at, a prompt generator, and a prompt generator that returns the settings to run a prompt at, not just a longer sentence.

The first image is free on a free account, no card and no waitlist. Failed, timed-out and moderation-blocked runs never cost credits on any tier, and the pricing page prints the measured upstream cost per image next to the retail price.

Two things it does not do, and says so on the page rather than in the small print: no transparent PNG yet, and no cross-session identity lock.
