It hasn't launched. What exists is a reference in OpenAI's own API spec and a new editing option attached to it — so this page documents that, says plainly what nobody knows, and runs the current model in the meantime.

Our one-line verdict: there is nothing to evaluate yet. This page exists so you can check a status rather than read invented specifications — and it becomes a real model page the week there's a real model.
Search for an unreleased model and you'll find a dozen pages listing its resolution, its speed and its benchmark position. None of that is real. What's actually documented about GPT Image 2.6 is narrow: OpenAI's public API specification references the identifier, and a new markup image-editing option in that spec states it supports GPT Image 2.5 and 2.6. That's the whole verifiable surface — no announcement, no date, no pricing, no capability claims. So rather than pad this page out, we've written down what's known, what isn't, and what to use in the meantime. The structure below is the same one every model page here uses; the sections simply say "not published" where the facts don't exist yet, and they'll be filled in the week they do.
On a released model these columns are strengths and limits. On this one they're what's documented and what isn't — the right-hand column is the part other pages fill in with guesses.
• A model ID exists in OpenAI's own API spec.
Public API specification updates reference an unannounced gpt-image-2.6. That's OpenAI's own documentation rather than a rumour site, which is the only reason this page exists at all.
• A new “markup” editing option is attached to it.
The spec adds a markup image-edit parameter stating that it supports GPT Image 2.5 and 2.6 — suggesting edits directed by marking up an image rather than describing the change in prose.
• Both versions are targeted together.
The dual-version callout implies 2.5 stays available for stability while 2.6 takes the newer capabilities — the same pattern OpenAI used when 2.5 arrived alongside GPT Image 2.
• Nothing else.
That is the complete list of what is documented. Everything beyond it, on this page or anywhere else, is inference — and we've put ours in the right-hand column where it belongs.
• The release date.
No announcement, no event, no date. API spec references have preceded launches by days and by months; this one could go either way, and we're not going to invent a quarter to fill the gap.
• Every specification.
Resolution, speed, pricing, context length, benchmark position — none of it is public. Any site listing specs for 2.6 today is making them up, which is a useful test of whether the rest of their content is worth reading.
• Whether it's a refinement or a generation.
GPT Image 2.5 was a refinement of 2 — faster, steadier multi-turn edits, same architecture. Whether 2.6 follows that pattern or brings something structural is unknown.
• Whether the name survives.
Leaked identifiers get renamed before launch. The model may ship under a different label entirely, in which case this page redirects.
These run on GPT Image 2.5 in the generator above. Prompt language has transferred across every OpenAI image version so far, so the wording you settle on now should carry over on launch day.





"A product photo of [a ceramic pour-over kettle] on a walnut counter, morning window light, steam rising, shallow depth of field." Then, one per turn: "warm the light one stop" → "swap the counter for pale marble" → "add a linen cloth at the left edge" → "tighten to a three-quarter close-up."
Small single-change turns are what the current generation handles best, and prompt language has transferred across every OpenAI image version so far — so the wording you settle on now should carry straight over. Runs on GPT Image 2.5 in the generator above.




Upload: 2–3 photos of your [product or model]
"Place the subject in four settings: a sunlit kitchen, a rainy street window, a studio seamless, a wooden workbench. Same subject, distinctly recognisable in every one, lighting appropriate per scene."
Subject preservation across settings is the thing 2.5 improved most, and the most likely area for 2.6 to build on. Naming both requirements — recognisable subject, scene-appropriate light — is what stops the four shots collapsing into one look.

Write the brief you'd want to re-run the day a new model lands: subject, lighting, composition, the exact text, and what must not change between versions.
The practical way to prepare for a release with no date is to have a fixed benchmark prompt of your own. Run it on 2.5 today, keep the output, and re-run it on 2.6 the week it ships — that comparison will tell you more than any launch post.
The same comparison every model page here carries — with the first column honest about being empty. It fills in the week OpenAI publishes something.
No. As of today it has not been announced or released. The only public evidence is a reference to gpt-image-2.6 in OpenAI's own API specification, alongside a new markup editing option that names both 2.5 and 2.6. There is no date, no pricing and no capability documentation.
