The explanations come shortly after explaining the GPT-5, Openai’s highly anticipated AI model. Musk also said that the Grok 4 thinking model is higher than the GPT-5 in the Arc-AGI 2 leadership table.

When we look forward, Tesla and SpaceX CEO Gok 5 will begin before the end of this year. “Grook 5 will go out before the end of this year and will be overwhelmingly good,” he said.

In the meantime, Openai said that the GPT-5, which emerged during a live stream event, is more capable of coding and creative writing and CEAHTIG through complex queries. CEO Sam Altman described the GPT-5 as a “big upgrade”, one of the previous models of Chatgpt Maker.

The GPT-5 is offered to all free chatgpt users and many paid subscribers, and corporate and training customers are preparing to get access the next week.
