Grok Imagine Video 1.5 is now generally available in the xAI API as `grok-imagine-video-1.5`, with Video 1.5 Fast also rolled out on grok.com/imagine and mobile apps. It improves audio, motion, physics, and generation speed, and adds Projects, multiple agents, and library search.

  • Allows multiple agents to run in parallel on projects.
