Vercel AI SDK adds Grok 4.5 model support and video reference inputs
Vercel shipped AI SDK version 3.0.106 for xAI integration, adding support for xAI's Grok 4.5 model and expanding video generation capabilities.
What changed
The patch includes two feature additions:
Grok 4.5 model identifier: The SDK now recognizes the grok-4.5 model ID, allowing developers to target xAI's latest model through Vercel's unified API interface. The model itself was previously announced by xAI but this marks its addition to Vercel's SDK.
Video reference inputs: The inputReferences parameter now accepts video files, not just images, for reference-to-video generation workflows. This enables developers to use existing video content as reference material when generating new video outputs.
The release also updates three dependency packages: @ai-sdk/provider to 3.0.14, @ai-sdk/openai-compatible to 2.0.59, and @ai-sdk/provider-utils to 4.0.38.
Technical context
Vercel's AI SDK provides a unified interface for accessing multiple AI providers through a single codebase. The xAI package specifically handles integration with xAI's API endpoints, including the Grok model family.
The video reference feature extends the SDK's multimodal capabilities beyond image-to-video generation. Developers can now pass video files as reference inputs, though the changelog does not specify supported video formats or file size limits.
What this means
This is a standard maintenance release that keeps Vercel's SDK current with xAI's model lineup. The Grok 4.5 addition allows developers using Vercel's abstraction layer to access the model without modifying their integration code.
The video reference input feature addresses a specific use case for developers building video generation applications, particularly those requiring style transfer or content-aware video synthesis. However, the actual video generation capabilities depend on the underlying model's support for these features—the SDK update only ensures the reference data can be passed through the API.
Developers using the AI SDK can update by running npm install @ai-sdk/xai@3.0.106 or the equivalent command for their package manager.
