What is Grok Imagine?

Grok Imagine is the image and video generation model from xAI, the company behind the Grok assistant. Its video mode turns a short text prompt into a clip with motion and sound. On GenModelHub you can run the Grok Imagine video model directly from this page and pay per clip with credits – you don't need an X account or a Grok subscription. At 1 credit per second it is one of the cheapest models on the site, so it is a good place to try an idea before using a heavier model.

How to use the Grok video generator

1. The generator at the top of this page is already set to Grok Imagine.

2. Write one or two sentences: subject, action, setting, camera. Example: "A red fox trots across a snowy field at sunrise, low tracking shot, breath visible in the cold air."

3. Choose 6 or 10 seconds and a format – 9:16 for TikTok, Reels and Shorts, 16:9 for YouTube, 1:1 or 2:3 for feeds.

4. Press Generate. A clip usually takes one to three minutes. Play it, download the MP4, or change one part of the prompt and run it again.

Grok Imagine prompt tips

Start with the subject and the action, then add the place, the light and one camera move. Short, concrete prompts work better than long lists of adjectives. Name the sound you want ("waves and gulls", "crowd cheering") if it matters. For a series of clips, keep the same description of your character and change only the action.

Grok Imagine vs Seedance and Veo

Grok Imagine and Seedance 1.5 Pro are the lowest-cost models here at 1 credit per second, and both add sound. Seedance 1.5 Pro allows up to 12 seconds; Grok Imagine offers more formats (2:3 and 3:2). Veo 3.1 Lite is also 1 credit per second and is the choice for generated dialogue. For the most consistent motion and multi-shot scenes, step up to Seedance 2.0 or 2.5.

Frequently asked questions

Is the Grok video generator free?

New visitors get free credits and signing in adds more – enough for a first Grok Imagine clip. After that it costs 1 credit per second: a 6-second video is 6 credits.

Do I need a Grok or X subscription?

No. GenModelHub runs the Grok Imagine video model through an API provider, so you only need a GenModelHub sign-in to keep your credits.

Is this the official Grok website?

No. GenModelHub is an independent service and is not affiliated with xAI or X. Grok and Grok Imagine are names of xAI products, used here only to describe the model.

How long are Grok Imagine videos?

6 or 10 seconds per clip at 720p. Generate several clips and join them in any video editor for something longer.

What content is not allowed?

Sexual content, real people without their consent and anything illegal are not allowed. If the model provider rejects a prompt, the generation fails and your credits are refunded automatically.
