Is Grok Imagine free?
It depends on the access route and what you want to create. xAI lists a $0/month plan with limited usage and limited Imagine image generation. Its plan comparison does not give an exact free quota or establish that free-plan users get video generation. (xAI pricing)
For image-to-video, fal.ai advertises a separate offer: five free Grok Imagine Video 1.5 Lite generations per rolling 24-hour window in its sandbox for signed-in fal.ai users. This is fal.ai’s offer, not evidence that Grok Imagine is free through xAI’s own app or website. The quota and access details below reflect fal.ai’s offer page; check that page and the sandbox for current availability before relying on them. (fal.ai free offer)
What each free route means
| Route | What the provider says | Scope and limits |
|---|---|---|
| xAI plan | The Free plan is listed at $0/month, with limited usage and limited Imagine image generation. | The plan comparison does not give an exact image quota or say whether free-plan video generation is included. |
fal.ai sandbox |
Signed-in users are offered five free generations per rolling 24-hour window. | This offer is specifically for Grok Imagine Video 1.5 Lite image-to-video in the fal.ai sandbox—not a general free allowance for every Imagine feature or platform. |
| API | API generations are billed separately from consumer-plan and sandbox access. | Check the provider and exact model: rates vary by model, resolution, duration, and input type. |
How to try Grok Imagine for free
On xAI’s app or website: xAI lists a free plan with limited Imagine image access, but the plan comparison does not state a numerical allowance or confirm free video access. Review the current plan details for the feature you need before subscribing. (xAI pricing)
For fal.ai’s image-to-video sandbox:
- Create or sign in to a
fal.aiaccount. - Open Grok Imagine Video 1.5 Lite image-to-video in the fal sandbox.
- Upload a starting image and write a prompt describing the motion, camera movement, and sound you want.
- Check the sandbox’s displayed allowance, then generate.
fal.ai’s offer page describes five free generations per rolling 24-hour window; current availability should be confirmed on the offer page and in the sandbox.
This offer covers image-to-video: it animates a still image into a video. It does not establish free access to text-to-image generation or image editing. The Grok app listing describes broader image and video features, but does not give feature-specific free-access terms. (Google Play listing)
What does Grok Imagine API video cost?
For xAI’s grok-imagine-video API model, xAI’s documentation lists output-video pricing of $0.05 per second at 480p and $0.07 per second at 720p. It separately lists image input at $0.002 per image and video input at $0.01 per second. These are API charges, not monthly subscription prices. (xAI model documentation)
Example: one 10-second, 720p clip from a single input image
- Video: 10 seconds × $0.07/second = $0.70
- One image input: $0.002
- Estimated total: $0.702
This calculation uses the listed video and image-input rates; it excludes any charges not shown in those rates.
Check the model version before comparing quotes
xAI lists different output rates for Grok Imagine Video 1.5 Preview: $0.08/second at 480p, $0.14/second at 720p, and $0.25/second at 1080p. Confirm the model name, resolution, and input charges in the relevant API documentation before estimating production spend. (xAI Grok Imagine Video 1.5 Preview documentation)
fal.ai also lists rates for its separate Grok Imagine Video 1.5 Lite image-to-video API: $0.02/second at 480p, $0.03/second at 720p, or $0.14/second at 1080p, plus $0.01 per input image. At the listed 720p rate, a 10-second clip with one input image works out to 10 × $0.03 + $0.01 = $0.31. These are fal.ai rates for that Lite endpoint—not xAI-direct pricing. (fal.ai Lite model pricing)
Bottom line
xAI lists a free plan with limited Imagine image access, but its plan comparison does not specify an exact quota or establish free video generation. For image-to-video, fal.ai’s offer page describes five free Grok Imagine Video 1.5 Lite generations per rolling 24-hour window for signed-in users in its sandbox; check the offer page and sandbox for current availability. For API budgeting, use the rates for the exact provider and model you plan to call, and account for resolution, clip duration, and input type.
