Grok 4.3 beta has been available to SuperGrok Heavy subscribers since April 17, claiming to feature 1T parameters, but Musk clarified that it is still 0.5T.
This version enhances context processing capabilities, supporting document generation and video input.
SpaceXAI is also training multiple models, including a 10T model, which is expected to be completed within a month.
The simultaneously released Grok Computer can perform multi-step tasks.
