The new version, called GPT-5.2, is described by Altman as “the smartest publicly available model in the world,” and Altman also adds that the model is “especially good for performing real-world scientific workloads.”
GPT-5.2 is here! Available today on ChatGPT and API.
It's the smartest public domain model in the world and is especially good for real-world knowledge-based tasks.

The update has already started rolling out to paid users and is also available in the developer API, as mentioned in a post on X/Twitter. This means that if you pay for ChatGPT Plus, Pro, Go, Business or Enterprise, you can start using the updated 5.2 model today.
According to OpenAI, the newly released GPT-5.2 has already achieved high scores across several criteria, where it “outperforms industry professionals on well-defined scientific work tasks covering 44 professions.”
According to press releaseGPT-5.2 Thinking is reported to perform a range of tasks requiring document processing, such as drawings, spreadsheets and legal briefs, at the level of a human expert or above. The company also claims that the update has reduced the number of “hallucinations” created by ChatGPT and that the number of erroneous responses has dropped by 30 percent.
According to Gizmodo, GPT-5.2 is reported to be ranked first and close in a number of tests, “significantly outperforming” Google rival Gemini 3 in the SWE-Bench Pro software development test.
Interestingly, OpenAI also claims that GPT-5.2 has made progress in safety, including responding when users show signs of struggling with their mental health. It now reportedly causes “fewer adverse reactions” in so-called sensitive situations.
The tech giant was recently sued for the wrongful death of an 83-year-old woman and her son following a murder-suicide following conversations with ChatGPT.
