Grok Imagine capabilities

  • Accepts text, image, and video as inputs. Enables text-to-video, image-to-video, and video-to-video workflows from one endpoint[^1]
  • Outputs video at 480p or 720p resolution, billed per second of generated output[^2]
  • Supports fourteen aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 2:1, 1:2, 19.5:9, 9:19.5, 20:9, 9:20, and auto (model selects the best ratio for your prompt)[^3]
  • Generates still images at 1K and 2K resolutions via the same Imagine API[^4]
  • Batch image generation supported: submit concurrent requests or use the n parameter to generate several images in one call[^5]
  • OpenAI-SDK drop-in compatible. Point your existing OpenAI client to https://api.x.ai/v1 and swap the model name[^6]
  • Delivers output as a temporary URL or base64-encoded data. No separate download step needed[^7]

FAQ

Grok Imagine FAQs

How much does Grok Imagine cost per second of video on Coinis?

On Coinis, Grok Imagine video is priced at $0.085/sec for both 480p and 720p output. A 4-second clip costs 4 x $0.085. A 15-second clip costs 15 x $0.085. You pay only for the seconds of video generated.

What is the difference between 480p and 720p, and is 720p worth the extra cost?

480p is the standard-definition tier suited for social previews, drafts, and high-volume pipelines where file size matters. 720p delivers HD output suited for ad placements, product videos, and anything viewed on a larger screen. On Coinis both tiers share the same $0.085/sec retail rate, so the choice is purely about output quality.

Can I use Grok Imagine for image-to-video, or only text-to-video?

Grok Imagine supports text, image, and video as inputs. You can pass an existing product photo or brand illustration as a conditioning input to generate an animated video output. Image and video input conditioning is billed separately by the vendor. See the official docs at https://docs.x.ai/developers/pricing for media input fee details.

Is there a Grok Imagine API, and is it OpenAI-compatible?

Yes. The Grok Imagine video endpoint on Coinis is available at POST https://api.app.coinis.com/v1/video/generate. The underlying xAI Imagine API is OpenAI-SDK-compatible. Teams already using the OpenAI Python or Node client can point their base URL to https://api.x.ai/v1 and swap the model name. The full API reference is on the Grok Imagine API sub-page.

How does Grok Imagine compare to other video models in the Coinis catalog?

Grok Imagine handles text-to-video, image-to-video, and video-to-video in one endpoint. Most catalog alternatives specialize in one mode. For higher-resolution or longer-form video, Coinis also offers Google Veo 3, Kling 2.1, and Runway Gen-4. Each model page includes its own pricing and capability details so you can compare before you generate.

What aspect ratios and clip lengths does Grok Imagine support?

Grok Imagine supports fourteen named aspect ratios including 1:1, 16:9, 9:16, 4:3, 19.5:9, 20:9, and an auto mode where the model picks the best ratio for your prompt. Clip length is flexible and billed per second of output. When editing a single image the output aspect ratio is locked to match the input image.

Are there content moderation or regional availability limits I should know about before building on Grok Imagine?

Two things to plan for. First, Grok Imagine enforces content moderation via a respect_moderation flag. Outputs that fail the policy check are filtered and not returned, so budget for occasional filtered requests in high-volume workflows. Second, model availability may vary by geography and account type. Check the official xAI docs or your Coinis account settings to confirm access before building a production pipeline.
