Native multimodal audio
Sound effects land on the action they belong to, with ambience, music and lip-synced dialogue produced in the same pass as the picture. Audio costs nothing on top of the per-second video rate.

Grok Imagine Video 1.5
Native multimodal audio, three modes in one model. One model covering text, image and reference input, from 1 to 15 seconds and up to 1080p, with sound effects, ambience, score and lip-synced dialogue generated alongside the picture rather than dubbed on afterwards.
The Studio runs the base Grok Imagine video endpoint today rather than these v1.5 endpoints, so the buttons open our text-to-video and image-to-video workflows; see /models/grok-imagine for the version you can generate with right now.

Features
What Grok Imagine Video 1.5 does differently.
Lifelike image-to-video
Fluid dynamics, steam, glass and reflections hold together under motion, and faces keep their micro-expressions and eye tracking instead of settling into a stare.
Three modes, one model
Text-to-video works from a prompt alone, image-to-video treats your still as the first frame, and reference-to-video takes one to seven images that the prompt addresses as IMAGE_1 through IMAGE_7.
Resolution priced per shot
480p, 720p and 1080p are billed at separate rates, so a rough cut can be drafted cheaply at 480p and only the approved shot re-rendered at 1080p.
