PendingSaid in the same tweet announcing Grok 4.5 (built on the 1.5T V9 foundation model) entering private beta at SpaceX & Tesla. The '@SpaceX' tag matches press reporting that the freshly-trained models will ship 'via SpaceX'; the cadence claim — a completely-from-scratch model each month through year-end — is the falsifiable part.
On June 28, 2026, while announcing that Grok 4.5 had entered private beta at SpaceX and Tesla, Musk said completely-from-scratch new AI models would be released every month for the rest of the year. The claim sets an aggressive monthly cadence of ground-up model training that far outpaces typical industry release schedules, where frontier labs usually ship a new foundation model once or twice a year. It is falsifiable at year-end: it holds only if a genuinely from-scratch-trained model ships in each remaining month of 2026.
