Grok Imagine 1.5 Private is an image-to-video generation model in xAI's Grok Imagine family, which converts a still image (plus an optional text prompt) into a short video clip. xAI's developer documentation lists a "Grok Imagine Video 1.5 Preview," billed per second of generated video and offered across multiple regional clusters. This private listing corresponds to that 1.5-generation video stack rather than a separately benchmarked public release.

As the newest entry in its image-to-video lineage, it follows Grok Imagine Private from mid-April 2026 and the earlier public Grok Imagine image-to-video model released in January 2026. The version bump to 1.5 signals an iteration on that same animation pipeline; xAI has not published official benchmark figures distinguishing the generations, so concrete quality deltas are not stated here.

Technically, the Grok Imagine video models animate static image inputs into motion clips, with typical API outputs running at 720p and configurable duration and aspect ratio.

The broader Grok Imagine suite spans related tools, including the Grok Imagine Private text-to-video and Grok Imagine R2V Private reference-to-video variants, the Grok Imagine image generator, and inpainting via Grok Imagine editing. All are reachable through xAI's Imagine API and the official Python SDK.
