The new version – Chat GPT5 – is free for all users of the tool, which according to the company is used by almost 700 million people per week.
CEO Sam Altman says that the new model is "generally intelligent".
It is a significant step towards models that are truly gifted, he says at a press conference on Thursday.
The new version comes more than two years after the launch of GPT4 in March 2023.
Expectations are high for Chat GPT5, as the San Francisco company has long been striving to develop artificial general intelligence (AGI) – a technology that can reason and acquire knowledge like a human.
But Altman warns that more is required before that type of artificial general intelligence is achieved.
According to Michelle Pokrass on Open AI's development team, one can see Chat GPT5 as a "representative" that independently solves its tasks.
Sam Altman describes earlier versions as talking to a high school student or a college student.
With GPT5, it feels for the first time like talking to an expert at a doctoral level in any subject.
While waiting for Open AI's news, competitor Anthropic released the latest version of its chatbot Claude earlier in the week.
