xAI's Grok Imagine 1.5 turns a still into video — and stakes a claim in the generative-video race

On 3 June 2026, xAI made grok-imagine-video-1.5-preview — its latest image-to-video model — available in preview via the xAI API. The pitch, per xAI, is straightforward and ambitious: feed it a single still image and it returns fluid, cinematic video, complete with camera moves, atmosphere and a sense of physics, while staying faithful to the source — at up to 720p.

Image-to-video is one of the most competitive frontiers in generative AI right now, and 'faithful to the source' is the hard part — animating a still without distorting the subject. xAI frames Grok Imagine 1.5 as doing exactly that. As a preview, it is an early, evolving release rather than a finished product, and the quality claims are xAI's own until independently tested.

For context — and attributed to xAI — its flagship language model Grok 4.3 is priced at $1.25/M input and $2.50/M output, with configurable reasoning effort. That positions xAI as competing on price as well as capability across both its text and creative-media lines. The strategic read on Grok Imagine 1.5 is less about any single clip and more about xAI assembling a credible, API-first creative toolkit alongside the labs it's chasing.
