        "prompt": "Describe what you want Grok Imagine Video 1.5 to generate.",
    },
)
job = response.json()

# Generation runs as an async job. Poll until it completes.

Grok Imagine Video 1.5 API parameters

Request parameters supported by the Grok Imagine Video 1.5 API on EmpirioLabs. Defaults apply when a field is omitted.

Good to know

Image-to-video model. Provide a source image and a prompt describing the motion to animate.

Defaults

• 10 second duration (1 to 15 seconds supported)
• 720p output (480p or 720p)
• Aspect ratio follows the source image unless set

Controls

Supports a source image (URL or upload), prompt, duration, resolution, and aspect ratio.

Billing

• Charged per second of generated video at the selected resolution (720p costs more per second than 480p), plus a per-source-image fee for the image you animate.
• A request that fails validation or errors out before any video is produced is not billed.
• A video that is produced but then blocked by content policy is still billed. This follows xAI usage policy, which charges for the generation even when the output is blocked by the content safety check. Keep prompts and source images within the usage policy to avoid this.
