Grok Imagine Video 1.5 from xAI is now available on AI Gateway. The model generates video from an input image with synchronized audio in a single pass.
This release improves audio quality, prompt following, and photorealism. Face accuracy and character consistency are stronger across longer sequences, with better lighting and physical realism in the output. Reference image support has been expanded to give more control over visual style and subject.
To use this model, set model to xai/grok-imagine-video-1.5-preview in the AI SDK. Chain an image model with Grok Imagine Video 1.5 to generate a still and animate it in one flow:
import { generateImage, experimental_generateVideo as generateVideo } from 'ai';const { images } = await generateImage({ model: 'xai/grok-imagine-image', prompt: 'A white rabbit sprinting down a NYC sidewalk at midday.', aspectRatio: '16:9',});const image = images[0];const imageDataUrl = `data:${image.mediaType};base64,${Buffer.from(image.uint8Array).toString('base64')}`;const { videos } = await generateVideo({ model: 'xai/grok-imagine-video-1.5-preview', prompt: { image: imageDataUrl, text: 'The rabbit darts past taxis as pigeons scatter.', }, aspectRatio: '16:9', providerOptions: { xai: { resolution: '720p' }, },});You can also try this Grok Imagine Video 1.5 directly in the AI Gateway Playground.
