Vercel AI SDK Adds Support for Google's Deep Research Models and Gemini Embedding-2

Vercel shipped version 5.0.0-canary.98 of its Google Vertex AI SDK package, adding support for three new Google models: deep-research-max-preview-04-2026, deep-research-preview-04-2026, and gemini-embedding-2.

The update applies to both the @ai-sdk/google-vertex and @ai-sdk/google packages, bringing the same model support to developers using either Google's Vertex AI platform or standard Google AI services.

New Models Added

The deep-research-max-preview-04-2026 and deep-research-preview-04-2026 models represent Google's research-focused model variants, though specific capabilities and pricing have not been disclosed. The "04-2026" designation in the model names suggests an April 2026 preview snapshot.

The gemini-embedding-2 model is Google's latest text embedding model, succeeding the previous generation. Embedding models convert text into numerical vectors for semantic search, retrieval-augmented generation (RAG), and similarity matching applications. Technical specifications and benchmark performance metrics have not been released.

Package Updates

The release bumps @ai-sdk/google-vertex to version 5.0.0-canary.98 and @ai-sdk/google to version 4.0.0-canary.75. Both packages maintain compatibility with Vercel's AI SDK framework, which provides unified interfaces for working with multiple AI providers.

Developers using the Vercel AI SDK can now access these models through the same API patterns used for other Google models, without requiring separate integration work.

What This Means

This SDK update primarily benefits developers building on Vercel's platform who want early access to Google's research models. The canary release status indicates these are preview versions intended for testing rather than production deployment. The lack of detailed documentation on model capabilities suggests Google is testing these variants with a limited developer audience before broader release. Organizations evaluating embedding model options now have access to Google's latest generation through a standardized SDK interface.
