About Grok Imagine Video 1.5 Preview
Grok Imagine Video 1.5 Preview is the preview build of xAI's Imagine Video 1.5 generation, released May 30, 2026 on AI Gateway. Grok Imagine Video 1.5 Preview generates video from an input image with synchronized audio in a single pass. Over the earlier Grok Imagine Video model, the 1.5 generation improves audio quality, prompt following, and photorealism. Face accuracy and character consistency hold across longer sequences, with better lighting and physical realism. Expanded reference image support gives more control over visual style and subject.
Integration runs through the AI SDK's generateVideo function, imported as experimental_generateVideo from AI SDK 6 or later. Pass a prompt object with an image and a text motion description. You control duration, aspect ratio, and resolution through parameters, with output available at 480p, 720p, and 1080p. Billing is per second of generated video, with rates by resolution shown on this page.
The stable grok-imagine-video-1.5 has since shipped as the production release of the same generation. Keep Grok Imagine Video 1.5 Preview for integrations you validated during the preview window, and plan new work against the stable model. You can compare both in the AI Gateway playground at https://ai-sdk.dev/playground/xai:grok-imagine-video-1.5-preview.
What To Consider When Choosing a Provider
- Configuration: Grok Imagine Video 1.5 Preview is a preview build, and the stable
grok-imagine-video-1.5is the variant to target for new production work. Keep the preview pinned only where you validated behavior against this specific build. - Configuration: Video generation through AI Gateway requires AI SDK 6 or later and uses
experimental_generateVideo, an experimental API that may change between releases. Generation can take minutes, so extend fetch timeouts in Node.js. Output is billed per second of generated video, and rates vary by resolution. - Zero Data Retention: AI Gateway does not currently support Zero Data Retention for this model. See the documentation for models that support ZDR.
- Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
When to Use Grok Imagine Video 1.5 Preview
Best For
- Validated Preview Workloads: Integrations tested against this build keep consistent behavior
- Image-To-Video Generation: A starting image plus a motion prompt returns a finished clip
- Audio-Inclusive Clips: Sound effects, ambience, and speech render in the same generation pass
- Style-Controlled Generation: Reference image support steers visual style and subject
Consider Alternatives When
- New Production Work:
grok-imagine-video-1.5is the stable release of the same generation - Text-Only Prompting:
grok-imagine-videogenerates clips straight from text descriptions - Static Visuals:
grok-imagine-imageorgrok-imagine-image-procovers stills without video cost
Conclusion
Grok Imagine Video 1.5 Preview is the early-access build of the Imagine Video 1.5 generation on AI Gateway. Image-to-video generation, synchronized audio, and reference image support all work through the AI SDK's generateVideo function. For new projects, start with the stable grok-imagine-video-1.5 instead.
