xAI's announcement makes Imagine Video 1.5 generally available in the Imagine API. It claims clearer, better-synced speech with sound effects, ambience and dialogue generated in the same pass, and more consistent motion with fewer warps. The July API update added text-to-video, reference-to-video and preset voices with native 1080p.
