Musk: SpaceX plans to release a brand new AI model every month this year

Odaily reported that Musk posted on his social media platform X, stating that his latest large language model, Grok 4.5, has officially entered Beta testing internally at SpaceX and Tesla, with a broader rollout to follow later. Musk also said that SpaceX plans to release a completely new AI model “trained from scratch” every month for the remainder of the year. This statement suggests that future versions may not simply be incremental improvements to existing systems, but entirely new foundation models built through fresh training runs.
