Grok Imagine 1.5 Adds References and Native 1080p

Grok Imagine 1.5 now supports image references, text-to-video, and native 1080p generation. xAI says a generation can use up to seven image references, letting a creator hold a character, product, or location steady while changing the scene. The same announcement shows a six-second, 16:9 API request using grok-imagine-video-1.5. 1

The same-day test is simple: keep one image for the subject, add a second image for the location, and change only the action. API voice-reference access is listed as available on request, so that boundary should decide whether an existing workflow gets replaced today. 1
