Google is piloting a new approach for Gemini for Business by allowing access to third-party models directly within its model selector. The appearance of Claude Sonnet 4.5 in the selection list indicates that Google is considering giving business customers more choice, likely leveraging existing integrations already present in Vertex AI. For organizations using Gemini for Business, this would mean the ability to switch between Google’s own models and select alternatives, potentially enabling more robust workflows and providing options for those who need specific model capabilities or prefer different model architectures.
At this stage, access to external models like Claude Sonnet 4.5 appears limited to the chat interface, not yet extending to agent-building tools. If adopted, this move could signal a broader trend toward interoperability, where business users benefit from having multiple high-performing models available within a single platform. This approach aligns with recent industry trends, as solutions built on a mixture of models from various vendors have shown potential for improved output quality.
Within the agent builder, Google is also developing a revamped runs and executions view. This update would let users inspect previous job runs tied to scheduled agent executions, though this functionality remains unreleased to most users. The broader context for these updates is Google’s ongoing effort to strengthen Gemini for Business with features that appeal to enterprise customers seeking flexibility and advanced operational visibility. Whether external models like Sonnet 4.5 will see a full release or remain in limited testing is yet to be determined, but these developments suggest Google is actively positioning Gemini for Business as a comprehensive AI platform.
