xAI Launches Grok Imagine Video 1.5, Tops Image-to-Video Arena Leaderboard
xAI released Grok Imagine Video 1.5 on May 31, 2026, which jumped 52 Elo points to claim the number-one position on the Image-to-Video Arena leaderboard. The model generates 720p video at 24 fps with native audio in clips of 6–15 seconds from still images. As of June 3, xAI added Quality Mode to the Grok Imagine API, bringing higher realism and stronger text rendering for enterprise developers.
Why it mattersNative audio in the same generation pass removes a key post-production bottleneck for video creators and positions Grok Imagine as a direct competitor to Sora and Runway Gen-3.
