Google is testing a new feature for Gemini for Business that allows users to access third-party models directly in its model selector. The inclusion of Claude Sonnet 4.5 in this list suggests Google aims to enhance choices for business customers, likely building on existing integrations seen in Vertex AI. This change enables organizations to switch between Google’s models and alternative options, offering more flexibility and potentially improving workflows for users who require specific capabilities or prefer different architectures. Currently, access to external models like Claude Sonnet 4.5 is limited to the chat interface, with no availability in agent-building tools yet. If this feature gains traction, it could indicate a shift toward interoperability, allowing business users to utilize multiple high-performing models within one platform. This aligns with industry trends where mixed-model solutions from various vendors have shown enhanced output quality. In tandem, Google is working on a new runs and executions view within the agent builder. This feature would allow users to review past job runs connected to scheduled agent executions, though it has not yet been released to the majority of users. These updates reflect Google’s strategy to improve Gemini for Business by adding features that appeal to enterprise clients looking for greater flexibility and better operational insights. The future availability of external models like Sonnet 4.5 remains uncertain, but these developments indicate Google is positioning Gemini for Business as a more comprehensive AI platform.
