xAI has released the Grok Imagine API, a new AI video generation and editing platform that has quickly climbed to the top of Artificial Analysis rankings for both text-to-video and image-to-video outputs.

The API supports text-to-video, image-to-video, and direct video editing workflows, generating clips up to 15 seconds long with native audio included. Editing features allow creators to swap objects, restyle entire scenes, animate characters with custom performances, and dynamically alter environments on command.

Grok Imagine is priced aggressively at $4.20 per minute with audio included, significantly undercutting competitors such as Google’s Veo 3.1 at $12 per minute and OpenAI’s Sora 2 Pro at $30 per minute. This pricing positions xAI as one of the most cost-efficient options for high-quality AI video generation.

In benchmark results, Imagine debuted at No. 1 on Artificial Analysis leaderboards for text and image-to-video tasks, while ranking just behind Veo 3 and Sora Pro on Arena’s Video Arena, signaling strong competitive quality alongside its lower cost structure.

Why it matters: AI video generation is rapidly becoming a commodity layer, and pricing pressure is now as important as raw quality. If Grok Imagine’s performance holds up at scale, xAI’s aggressive pricing could make it the default choice for creators and developers who need fast iteration without burning through budgets.
