Imagine Video 1.5 with References

When we launched Imagine Video 1.5 last month, it was our best video model yet — better motion, better physics, and better audio. Today it goes further: image and voice references, video from a prompt alone, and native 1080p generation.

Image and voice references start today in the US for SuperGrok Heavy and SuperGrok Plus on grok.com/imagine and iOS, rolling out to all tiers over the next few days.

Describe the shot — no starting image needed. Text-to-video pairs our image generation with image-to-video. Native 1080p is now supported with text-to-video and image-to-video. Text-to-video and native 1080p are generally available on grok.com/imagine, iOS, and Android.

Pass in a character image and a voice reference, and both hold — the same face and the same voice in every scene.

Each reference image locks one thing in place — a face, a product, a location. Keep a character and swap the scene, keep the scene and swap the character, or hold both and change only the action. Up to seven references per generation.

Image references, text-to-video, and native 1080p are live in the xAI API with our best video model, grok-imagine-video-1.5. Voice reference support is available on request.
