Grok Imagine Video — AI video generator

xAI's video model with native synchronized audio

Grok Imagine Video is xAI's video model, built to generate the soundtrack alongside the picture rather than as a separate step. Its duration range is unusually wide at the short end, which makes it a good fit for the one- and two-second cuts that social edits are actually built from.
