New GPT Image 2.5 surfaces inside ChatGPT before launch, can already fake GPT-6 event images

OpenAI's new image model GPT Image 2.5 is already surfacing inside ChatGPT before an official announcement, with test results showing it can fabricate convincing GPT-6 launch photos and tweet screenshots. Compared with GPT Image 2, it generates faster, looks more photorealistic, keeps faces and embedded text stable, and fixes the earlier noise artifacts.

Published

Just as OpenAI wrapped up its GPT-6 launch, a batch of highly convincing “photos from the event” began circulating on social networks. Chinese tech outlet QbitAI reports they were produced by OpenAI's new image model, GPT Image 2.5, which has not been officially released but has already reached some users as a new popup prompt inside ChatGPT.

The version number is the first surprise: instead of the GPT Image 2.1 many expected, the model jumped straight to 2.5, suggesting a substantial upgrade. According to test results circulating online, it can now fabricate official-looking GPT-6 launch images as well as an all-staff letter and tweet screenshots from Sam Altman, with text that shows almost no flaws apart from an incorrect avatar.

On the LMArena leaderboard, an anonymous model codenamed luna-lisa-alpha is widely believed to be the new GPT Image. Community testing has identified several traits: very fast generation, more lifelike photos, faces that stay stable across multiple images of the same character, embedded text that resists distortion, and a fix for the noise artifacts that plagued GPT Image 2.

One tricky test asked the model to produce a realistic phone photo of a handwritten article in Albert Einstein's handwriting on ruled paper, with a coffee stain in the upper-right corner. Placed next to the real Einstein handwriting, the output is nearly indistinguishable.

OpenAI's product placement hints at how much weight image generation now carries: the ChatGPT web app briefly moved image generation up to the second slot in its main menu, right below “new chat,” before hiding it again. The rising prominence of image generation inside ChatGPT suggests it will become one of the flagship features of the GPT-6 era.

The open question is when OpenAI will make the model official, since the final version number, rollout scope, and API pricing have not been announced. How image generation will combine with GPT-6 Astra's push toward “completing work” is the next thing to watch.

Why it matters

GPT Image 2.5 shows OpenAI's image generation stack improving quickly while still unofficial, signaling image generation as a core GPT-6-era feature and adding fresh urgency to the fight against AI-generated fakes.
