Last night (December 10-11, 2025), there was no official announcement from xAI, Elon Musk, or the Grok account about a new update to Grok Imagine's video generation feature. However, many users on X reported noticing a **silent model change or rollback** in the video generation engine overnight. Several creators shared side-by-side comparisons showing that the "new" outputs (from today) have significantly less motion, more static poses, reduced dynamism, and often default to slow zooms or minimal animation — a clear downgrade in quality compared to the previous version (which had more lively movement and better physics). Examples of user feedback from the last 12–24 hours: - Multiple posts describe the current model as "terrible," "boring," "static," or "a huge step backward." - Complaints about the same generic piano music persisting in many clips. - Some users speculate it might be a temporary rollback due to safety/filtering issues or preparation for a bigger upcoming update (possibly Grok 4.5 integration). In short: no exciting new feature dropped last night — instead, it looks like the video model quietly got nerfed or swapped to a more conservative/cautious version, and the community is not happy about it. xAI often iterates silently in beta, so this could be fixed soon or building toward something better.
