Parameter shrinkage but the factory is running smoothly; a new base version every two weeks. Can traditional AI companies keep up with this pace?

Sources say that Grok 4.3 (beta) has been opened to top-tier subscribers, and it was previously rumored to have 1 trillion parameters with longer training times. Elon Musk clarified that this version is just a 0.5 trillion update checkpoint, not a new 1 trillion model; the true 1 trillion flagship is expected to complete initial training in about five days, at which point it will achieve leaps in coding, long context, and various skills. The SpaceXAI model factory has already been tested, and improved base models will be offline every two weeks.
