The Vercel AI SDK has received several updates, as detailed in its changelog. These include improvements to the xAI provider, new model integrations, and enhancements to the sandbox environment. The @ai-sdk/xai@4.0.39 release, dated August 14, addresses how video moderation blocks and missing URLs are handled, changing them from throwing errors to reporting an error status.

Separately, the @ai-sdk/xai@3.0.121 release introduced support for the Grok Imagine Video 1.5 model, enabling native 1080p resolution for text-to-video and image-to-video generation. This update also added functionality for reference audio in reference-to-video, allowing up to 3 xAI preset voice IDs to be passed and referenced within prompts. The @ai-sdk/google@3.0.109 release, also on August 14, added the Gemini 3.7 Flash model. Concurrently, the @ai-sdk/sandbox-vercel@1.0.72 release, dated August 14, introduced support for request transformations in its network sandbox abstraction, facilitating credential brokering.

Key Points
