# Google gives all of its engineers Claude Opus 5 access via Antigravity, and says "Gemini remains our primary and foundational model for internal development" (Hugh Langley/Business Insider)

> In a quietly telling move, Google has given all of its engineers access to Anthropic's Claude Opus 5 through its internal Antigravity tooling, according to a Business Insider report. The company was quick to add a caveat, stressing that Gemini remains its primary and foundational model for internal development. The detail matters because Google is not just a customer here, it is one of the fiercest competitors in frontier AI, pouring billions into making Gemini the model of record. Handing engineers a rival's flagship anyway suggests that inside the company, the priority is shipping good software rather than loyalty to a single family of models. Developers, it turns out, want to use whatever works best for the task in front of them. It also underscores how the coding assistant market has become a real battleground, with Anthropic's models widely praised for programming work. Google's careful wording reads like an attempt to have it both ways, embracing Claude's strengths while reassuring everyone that its own model is still the house standard.
