Grok Imagine Private is a text-to-video model from xAI, part of the broader Grok Imagine family that converts text prompts and images into short visual clips with coherent motion and synchronized audio. The "Private" label denotes an internal or staging variant within xAI's text-to-video line, dated April 2026 in this catalog. Like other Grok Imagine models, it is designed for end-to-end creative workflows and fast visual ideation through the xAI Imagine API.

Compared with the original public Grok Imagine text-to-video model released in January 2026, this later iteration sits in the same lineage that xAI has steadily expanded. A defining feature across the family is native, timed audio with lip-sync, which lets creators skip separate voice recording for many workflows. Generation is exposed through xAI's video and Imagine API endpoints documented for the suite.

The Grok Imagine ecosystem spans multiple modalities and entry points, including image-to-video siblings such as Grok Imagine Private and the newer Grok Imagine 1.5 Private, plus reference-to-video and video editing variants. xAI documents the model's text-to-video and audio generation capabilities within its developer materials.

Because dedicated technical documentation and independent evaluation for this specific private endpoint are limited, the details above are drawn from xAI's public Grok Imagine materials and should be treated as family-level characteristics rather than endpoint-specific specifications.
