Vercel's AI SDK has received updates across several packages, including changes to its sandbox functionality and expanded model support for Google Vertex. These updates were released on August 14.

Key Points

  • The @ai-sdk/sandbox-just-bash@1.0.72 and @ai-sdk/sandbox-vercel@1.0.72 packages now include getPortEndpoint().
  • getPortEndpoint() is a more comprehensive replacement for the deprecated getPortUrl() within HarnessV1NetworkSandboxSession.
  • The @ai-sdk/sandbox-vercel@1.0.72 update also supports request transformations in the network sandbox abstraction.
  • This transformation capability is used to apply credential brokering when available.
  • The @ai-sdk/google-vertex@4.0.182 package adds support for the Gemini 3.7 Flash model.
  • The @ai-sdk/xai@3.0.121 package introduces support for Grok Imagine Video 1.5.
  • Grok Imagine Video 1.5 supports native 1080p for text-to-video and image-to-video, with reference-to-video capped at 720p.

Context

According to Vercel's AI SDK changelog, the getPortEndpoint() feature was added to the harness component, which is a dependency for both @ai-sdk/sandbox-just-bash and @ai-sdk/sandbox-vercel. The integration of Gemini 3.7 Flash expands the range of models available through the Google Vertex provider. Additionally, the xAI provider now supports Grok Imagine Video 1.5, enhancing video generation capabilities.

Why It Matters

These updates provide developers using the Vercel AI SDK with enhanced sandbox networking capabilities and access to newer models from Google and xAI. The deprecation of getPortUrl() indicates a shift towards a more robust endpoint management system, while new model integrations expand the creative and functional possibilities for AI-powered applications.

What To Do

  • Developers using getPortUrl() in HarnessV1NetworkSandboxSession should transition to getPortEndpoint().
  • Review the updated @ai-sdk/harness documentation for details on getPortEndpoint() and network sandbox request transformations.
  • Explore the Gemini 3.7 Flash model via the @ai-sdk/google-vertex package for new application possibilities.
  • Investigate the Grok Imagine Video 1.5 model in @ai-sdk/xai for video generation tasks, noting the resolution capabilities and limitations.
