Grok Imagine Upscale - Unifically

Upscale a completed xAI Grok Imagine video to a higher-definition result. Provide the task ID of the source generation.

Upscale only works on videos generated with Grok Imagine Video (xai/grok-imagine-video, the speed-optimized 1.5 build). Task IDs from Grok Imagine Video 1.5 (xai/grok-imagine-1.5-video) are not supported — that model is API-level and separate.

Model

xai/grok-imagine-upscale

Parameters

Parameter	Type	Required	Default	Description
`task_id`	string	Yes	—	Task ID of a completed Grok Imagine video generation. Returns an HD-upscaled result.
