Grok Imagine Free: How to Make Grok Videos Without a Subscription

You can try Grok Imagine without paying for a monthly plan. The simplest way is a pay-per-clip generator: on GenModelHub's Grok video generator new visitors get free credits, signing in adds more, and a 6-second Grok Imagine clip costs 6 credits. There is no X account, Grok subscription or app install involved.

What Grok Imagine is

Grok Imagine is the image and video generation model from xAI, the company behind the Grok assistant. In video mode it turns a short text prompt into a clip with motion and sound. Inside xAI's own apps, access and limits depend on your account and plan, and those rules change from time to time, so check the app itself for the current details.

Through an API provider the same video model can be used by other services. That is how GenModelHub runs it: you write the prompt here, the clip is generated through the provider, and you pay per second instead of per month.

Three ways to use Grok Imagine for free or cheaply

1. In xAI's apps. If you already use Grok or X, look for the Imagine feature there. What is free and how many clips you get depends on your account, so treat this as "try what your plan includes".

2. With free credits on a pay-per-clip site. On GenModelHub the free credits for new visitors plus the sign-in bonus are enough for a first Grok Imagine clip. After that you pay only for what you generate: 1 credit per second, so 6 credits for a 6-second clip and 10 for a 10-second clip.

3. As a developer, through an API. If you build your own app, you can call the model through an API provider and pay per generation. This is the route with the most control, but it needs code and an API key.

What you get on GenModelHub

• Clip length: 6 or 10 seconds
• Resolution: 720p
• Sound: generated with the video
• Formats: 16:9, 9:16, 1:1, 2:3 and 3:2
• Price: 1 credit per second, failed generations refunded automatically

Credits cost between about $0.05 (Max plan) and $0.09 (Starter pack), so a 6-second clip works out to roughly $0.29–$0.54 once the free credits are used up. The cheap AI video generator page lists the cost of every model side by side.

How to make your first Grok video

1. Open the Grok video generator. Grok Imagine is already selected.
2. Write one or two sentences: the subject, what it does, where, and how the camera moves.
3. Pick 6 seconds for the first test and the format you need – 9:16 for TikTok, Reels and Shorts.
4. Press Generate. Most clips are ready in one to three minutes.
5. Download the MP4, or change one part of the prompt and try again.

Prompts that work well

Short, concrete prompts give the most predictable results. Some starting points:

• "A red fox trots across a snowy field at sunrise, low tracking shot, breath visible in the cold air."
• "Close-up of hands kneading bread dough on a floured wooden table, warm kitchen light, slow push-in."
• "A paper boat drifts down a rain-filled street gutter, camera follows at water level, sound of rain."
• "A skateboarder lands a kickflip in an empty parking lot at dusk, slow motion, wide shot."

Lead with the subject and the action, add the setting and light, and give the camera one instruction. If you care about the sound, name it ("waves and gulls", "crowd cheering").

Ways to stretch free credits

• Test every new idea at 6 seconds before rendering 10.
• Change one thing per attempt, so you know what made the difference.
• Reuse a fixed description of your character across clips for consistency.
• Join short clips in a video editor rather than generating one long clip.

Grok Imagine or another model?

Grok Imagine is one of three models on GenModelHub at 1 credit per second. Seedance 1.5 Pro allows longer clips (up to 12 seconds) and cinematic camera moves; Veo 3.1 Lite is the choice when people in the shot need to speak. For demanding multi-shot scenes, Seedance 2.5 is stronger but costs 10 credits per second.
