testingcatalog · x · 2026-08-01

xAI officially announced a major upgrade to its video generation model, Imagine Video 1.5, introducing Text-to-Video and native 1080p resolution support. Users can now generate high-quality video directly from prompts without needing a starting image.

Additionally, the model introduces image and voice references, allowing users to lock in a specific character's face and voice across multiple scenes for high consistency. A single generation supports up to 7 reference images to lock characters, scenes, or products. Image and voice references are currently available to SuperGrok Heavy and Plus subscribers in the US, with API support also rolled out.
