Announcement of Grok 4.5 private beta at SpaceX and Tesla, with performance near or exceeding Opus; new models to be released monthly by SpaceX.
“Grok 4.5, based on our 1.5T V9 foundation model, with Cursor data added in supplemental training, is now in private beta at SpaceX & Tesla. Early evals show performance close to, perhaps exceeding Opus. RL is continuing to significantly improve the model, and the Grok Build harness gets better every day. Nice work by all those involved! Completely trained from scratch new models will be released by @SpaceX every month this year.”Original post：X / @elonmusk ↗
