This is still 0.5T, but a more recent training checkpoint. 1T model is ~5 days away from finishing initial training. Will be a major step change improvement in coding, long context and skills. The SpaceXAI model factory is finally working. Should be an improved base model landing every ~2 weeks.

Supplemental training has been added to 4.3. Grok 4.4 will be twice the size (1T) with training data through early April. Probably ready for release in early May. Grok 4.5 will be 1.5T and hopefully out by late May.

SpaceXAI and @cursor_ai are now working closely together to create the world's best coding and knowledge work AI. The combination of Cursor's leading product and distribution to expert software engineers with SpaceX's million H100 equivalent Colossus training supercomputer will allow us to build the world's most useful models. Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.
