Grok Imagine API Launches With Video Generation and Editing
xAI opens the Grok Imagine API, a text-to-video, image-to-video and video-editing bundle with native audio that debuted first on Artificial Analysis's video leaderboards at $4.20 per minute.
- On 28 January 2026 xAI released the Grok Imagine API, 'a unified bundle' of video generation and video editing endpoints that it called its most powerful video-audio model yet
- It does text-to-video, image-to-video and instruction-based editing (add, remove or swap objects, restyle a scene, change weather or time of day), with dialogue, sound effects and music generated with the picture[2]
- Output is 720p or 480p and up to 15 seconds through the API at $4.20 per minute with audio, against $12 for Veo 3.1 and $30 for Sora 2 Pro[2][3]
- Artificial Analysis ranked it first for both text-to-video and image-to-video at launch, while Arena put it first for image-to-video and fourth for text-to-video; xAI's own editing test had raters preferring it to Runway Aleph 64.1% of the time[3]
- DeepLearning.AI measured an average generation time of 110.1 seconds, slower than Kling 2.5 Turbo but faster than Sora 2 Pro[3]; this API model became 'Grok Imagine 1.0' in the apps five days later
