xAI updated its best video model, Imagine Video 1.5 (grok-imagine-video-1.5), to support image and voice references, text-to-video and image-to-video without a starting image, and native 1080p output. Image and voice references start in the US for SuperGrok Heavy and SuperGrok Plus on grok.com/imagine and iOS (rolling out to other tiers in days); image references, text-to-video, and native 1080p are also live in the xAI API, while voice-reference support is available on request.
