Google Opens Claude Opus 5 to All Engineers via Antigravity
TL;DR
- Google has cleared every engineer to use Anthropic's Claude Opus 5 inside its Antigravity development environment, breaking a rule that had confined Claude to select DeepMind teams and high-priority projects.
- Staff still cannot use Anthropic's Claude Code or OpenAI's Codex directly; access is only via Antigravity with per-user quotas.
- Google says Gemini 'remains the primary foundation model for internal development,' with third-party models allowed on a quota basis for 'specialized use cases.'
Google has opened Anthropic's Claude Opus 5 to every engineer through Antigravity, its internal development environment, Business Insider's Hugh Langley reported. Access is metered by per-user quotas, and staff still cannot use Anthropic's Claude Code or OpenAI's Codex directly; they must select Opus 5 inside Antigravity.
Until now, Claude access at Google had been limited to select teams within Google DeepMind and a small number of high-priority engineering projects, and the company had barred employees from using outside coding tools, directing them to build with Gemini instead.
A Google spokesperson framed the change narrowly. "Gemini remains the primary foundation model for internal development, and third-party models are provided on a quota basis to support specialized use cases," the spokesperson said, adding that engineers can access "select third-party models in Antigravity, consistent with our external Antigravity enterprise offering."
The move lands amid a steady run of stories we've been tracking about Anthropic turning up inside rivals' stacks, including Apple wiring Siri to swap in Claude or ChatGPT the day before.
