Vercel has issued updates for its AI SDK, addressing timeout handling in the WorkflowAgent and refining the XAI provider. The @ai-sdk/workflow@1.0.67 release, dated August 14, focuses on ensuring absolute deadlines within durable model-call steps.

Separately, the @ai-sdk/xai@4.0.39 release, also from August 14, modifies how video moderation blocks and missing URLs are reported, changing them from throwing errors to reporting an error status. An earlier @ai-sdk/xai@3.0.121 update introduced support for Grok Imagine Video 1.5.

Key Points

  • The WorkflowAgent in @ai-sdk/workflow@1.0.67 now enforces absolute deadlines for durable model-call steps.
  • Timeout handling in the WorkflowAgent routes timeouts through abort handling.
  • @ai-sdk/xai@4.0.39 reports video moderation blocks and missing URLs as an error status instead of throwing an error.
  • The @ai-sdk/xai@3.0.121 release added support for Grok Imagine Video 1.5.
  • Grok Imagine Video 1.5 supports native 1080p for text-to-video and image-to-video.
  • Reference-to-video in Grok Imagine Video 1.5 remains capped at 720p.
  • The @ai-sdk/xai@3.0.121 update also added referenceVoiceIds for reference audio in reference-to-video, allowing up to 3 xAI preset voice IDs.

Context

According to Vercel, the WorkflowAgent update improves the robustness of long-running operations by ensuring that model calls adhere to strict time limits. The changes to the XAI provider, as noted by Vercel, aim to provide more consistent error reporting for video moderation and URL issues, and to expand its capabilities with Grok Imagine Video 1.5.

Why It Matters

These updates enhance the reliability and functionality of the Vercel AI SDK. Developers using the WorkflowAgent can expect more predictable behavior regarding timeouts, while those integrating with xAI models gain improved error handling and access to advanced video generation features, including 1080p output for certain Grok Imagine Video 1.5 modes.

What To Do

  • Review the @ai-sdk/workflow@1.0.67 changelog for details on timeout handling.
  • Note the change in error reporting for video moderation blocks and missing URLs in @ai-sdk/xai@4.0.39.
  • Explore the new Grok Imagine Video 1.5 capabilities within @ai-sdk/xai@3.0.121, particularly the 1080p support for text-to-video and image-to-video.
  • Test the referenceVoiceIds feature for adding reference audio to video generations using xAI.
