Vercel released version 4.0.10 of its xAI SDK provider, adding support for xAI's Grok-4.5 model and enabling video reference inputs for generation tasks.

Key Changes

The update adds the Grok-4.5 model ID to the xAI provider, making it accessible through Vercel's AI SDK. This follows xAI's recent release of the Grok-4.5 model series.

The SDK now supports video inputs in the inputReferences parameter, extending beyond the previous image-only capability. This enables reference-to-video generation workflows where developers can use existing video content as a reference for generating new video outputs.

Technical Details

The patch includes three commits:

  • Addition of Grok-4.5 model ID to the xAI provider
  • Video reference input support in inputReferences for reference-to-video generation
  • Dependency updates across the AI SDK stack including @ai-sdk/provider@4.0.3, @ai-sdk/openai-compatible@3.0.7, and @ai-sdk/provider-utils@5.0.7

The video reference feature applies to the broader AI SDK provider system, not exclusively to xAI models.

What This Means

Vercel continues expanding its AI SDK to support newly released models immediately after launch. The Grok-4.5 addition maintains the SDK's position as a model-agnostic abstraction layer for developers building AI applications. The video reference capability suggests increasing demand for video-to-video generation workflows in production applications, though actual model support for this feature depends on the underlying providers' capabilities.
