Elon Musk retweeted a post from XFreeze showcasing Grok Build's video editing capabilities. XFreeze stated that by simply instructing Grok Build to create a cinematic Cybercab video using officially released Tesla footage, Grok Build automatically searched and selected the best clips on X, planned the sequence, and produced a high-quality edited piece. The post also noted that users can provide their own footage, and Grok Build will handle the actual production.
