Is there a Grok Imagine free trial?
There is limited free-plan access to Imagine, rather than a confirmed fixed-duration trial. xAI’s plan page lists Free at $0/month and marks Imagine image and video generation as limited. It does not specify a guaranteed number of free generations or a trial length. (xAI plan page)
The API is a separate, metered route. xAI publishes per-second API prices for Imagine video models; free consumer access does not mean API generations are free. Check the model, resolution, and listed rate in xAI API pricing before generating.
Official access and third-party credits are different
For a no-API test, sign in to Grok on the web or in its iOS or Android app and try Imagine within the Free plan’s limited usage. xAI lists paid plans with higher usage, but the cited plan comparison does not state a fixed Imagine allowance for Free. (xAI plan page)
A CometAPI article claimed that it sometimes offered new users $1–$5 in signup credits and quoted $0.04 per second at 480p. Those are third-party claims, not an xAI trial or xAI API prices; the article does not establish credit eligibility, expiration, or eligible usage. (CometAPI article)
Listed Grok Imagine video API prices
The xAI pricing information lists these USD output rates. The rates below are per generated second; image input may also incur a separate charge. Confirm the applicable model and price in xAI’s API pricing.
| API model | 480p | 720p | 1080p |
|---|---|---|---|
grok-imagine-video-1.5-lite |
$0.02/sec | $0.03/sec | $0.14/sec |
grok-imagine-video |
$0.05/sec | $0.07/sec | Not listed |
grok-imagine-video-1.5 |
$0.08/sec | $0.14/sec | $0.25/sec |
Example budgets
These estimates multiply the listed output rate by the requested duration. They exclude applicable input-image charges and assume the full requested duration is billed at the listed rate.
| Model and output | 10 seconds | 15 seconds |
|---|---|---|
grok-imagine-video-1.5-lite, 480p |
$0.20 | $0.30 |
grok-imagine-video-1.5-lite, 720p |
$0.30 | $0.45 |
grok-imagine-video-1.5-lite, 1080p |
$1.40 | $2.10 |
grok-imagine-video-1.5, 1080p |
$2.50 | $3.75 |
For example, a 10-second 720p clip on grok-imagine-video-1.5-lite works out to 10 × $0.03 = $0.30 in output charges. The published model information lists $0.01 per image input pricing for the 1.5 and 1.5-lite models; add that when your request includes an image. The older grok-imagine-video listing shows $0.002 per image and $0.01 per second for video input. Check the applicable model details if you supply an image or existing video.

Choosing a model
Compare the listed rates and resolutions against your output requirements. The available xAI capability information specifically describes grok-imagine-video-1.5 as supporting text-to-video and image-to-video at native 1080p. It does not establish here the other model-selection distinctions sometimes claimed—such as Lite’s 1080p handling, editing or extension support, or reference-image, voice-reference, and pinned-frame support—so verify those capabilities in the model documentation before choosing based on them.
Does the production API support the capability you need?
The available xAI capability information describes text-to-video and image-to-video generation, clips up to 15 seconds, and native 1080p text-to-video and image-to-video for Video 1.5. Do not assume every model supports the same options; check the model-specific documentation for the mode, resolution, and duration you need. (Video API overview)
xAI’s generation documentation describes an asynchronous request-ID flow. Confirm the model identifier and the requested resolution, duration, and input type against the provider’s documentation before building around the API. (Video generation documentation)
Bottom line: Use Grok’s Free plan to try Imagine with limited consumer access. For production API use, budget by model, resolution, duration, and any image or video inputs. A $0 consumer plan or a third-party promotional credit does not establish free xAI API usage. Check xAI’s plan and API pricing pages before spending.
