Grok Imagine API
xAI's Grok Imagine line — image and short video, with the longest clips per dollar we carry.

个模型
Grok Imagine is xAI's generation line, covering both images and short video. Its distinguishing feature is duration: the video model accepts anything from 6 to 30 seconds in six fixed steps, at a price that starts under two cents — unusually cheap for clips that long. The image tiers are flat-priced regardless of framing.

如何选择
Grok Imagine 1.5 Video
Short video from a prompt, or animating a still. Duration from 6 to 30 seconds at 480p or 720p.
Grok Imagine 1.5 Image
Image generation that can also transform a reference image.
Grok Imagine 2.0 Image
Batch image generation from a text prompt, with more aspect ratios than 1.5 — but no reference input.
优势
- Video duration reaches 30 seconds in six fixed steps, which only Seedance 2.5 also matches.
- Image and video share one vendor and one key.
- Flat image pricing — framing choice does not change the cost.
限制
- Video stops at 720p; there is no 1080p or 4K option in this line.
- Grok Imagine 2.0 dropped reference-image input, so image-to-image work has to stay on 1.5.
- The two image tiers are priced identically, so 2.0 costs the same as 1.5 while accepting less.
