Today, Elon Musk, CEO of Tesla, officially announced on the X platform that the candidate release version (public beta) of the large model Grok4.2 developed by his company xAI is now officially available for user use.

Musk specifically mentioned in his tweet that he warmly welcomes users to provide valuable feedback on the Grok4.2 version. These opinions will serve as important references for the continuous optimization and improvement of the model.

Compared to all previous versions of Grok, the 4.2 version has achieved core upgrades, with the most significant change being the addition of a fast learning ability. This feature enables Grok4.2 to adapt to and master new information more quickly, thus providing users with more accurate and efficient service.
