Elon Musk Calls Grok Agent Mode 'Major Ability Unlock' After 4+ Minute Video Demo on May 19

According to BlockBeats, on May 19, Elon Musk commented on a user's post calling Grok Agent mode 'a major ability unlock.' The user demonstrated generating a video longer than 4 minutes using Grok Imagine's Agent mode, which automates script, scene, and dialogue generation without requiring additional voiceover work.

The user also noted that image reference features are now available and perform well in consistency and realism. Musk's endorsement highlights xAI's progress in extending Grok from a chat model toward an executable content production system.
