OpenAI 4.5 research preview is available to some pro users. There are reports that GPT4.5 has been leaked.

It is likely that GPT 4.5 could be widely available by Thursday or Friday.

Reports indicate that GPT-4.5 is on the verge of release, with evidence emerging from the ChatGPT Android app, where datamining uncovered references to a “GPT-4.5 research preview.”

This preview appears to be exclusively for Pro users—those on the $200/month tier—initially limiting access to this group.

The leak, spotted by multiple sources today, suggests the rollout could happen imminently, with some speculating it might even drop as early as today or tomorrow.

Rumors about GPT-4.5’s capabilities are swirling. It is a big step up from GPT-4 and might have used 50 times the compute power, enhanced by better synthetic data and powerful underlying models.

There are rumors speculation that it’s “highly intelligent” and “lie-aware,” with a unique reasoning style possibly relying on structured outputs or mathematical frameworks rather than the explicit chain-of-thought reasoning seen in models like o1 or o3.

Rumors of “human-like vision,” suggesting advanced multimodal features, though details remain vague.

Rumors: GPT-4.5’s preview is a testbed for features that will be mature for GPT-5.

Various people have reasons to spread good or bad stories about GPT 4.5.
