xAI is an American artificial intelligence company and wholly owned subsidiary of SpaceX. The company develops AI systems under the Grok brand, spanning language models, image generation, and video synthesis. xAI has quickly established itself as a multimodal…

Grok Imagine Private is xAI's video-to-video member of the Grok Imagine family, dated April 2026. Where text-to-video and image-to-video modes start from a prompt or a still, this variant is oriented around transforming or extending existing video. It belongs to the broader Imagine API, which xAI describes as a unified bundle for end-to-end creative workflows and as its video-audio generative model line. A defining trait of the family is native audio: dialogue, ambience, and sound effects are generated alongside the visuals rather than added separately.

Across the family, Grok Imagine produces short clips—xAI's documentation exposes duration, aspect-ratio, and resolution controls, with examples generating roughly 10-second 720p videos. The "Private" label marks this as a preview-stage configuration rather than a public general-availability release.

It sits beside several sibling modes released around the same window, including Grok Imagine Private for text-to-video, Grok Imagine Private for image-to-video, and Grok Imagine R2V Private for reference-guided generation. The newest overall step from this lineage is Grok Imagine 1.5 Private from late May 2026, a versioned successor on the image-to-video side.

Beyond the API parameters and feature set documented by xAI, public primary specifications for this specific video-to-video private variant are limited, so capability details should be confirmed against xAI's official Imagine documentation.
