Antigravity

A side-by-side comparison put three AI coding tools — Anthropic's Claude Code, OpenAI's Codex and Google's Antigravity — to the test, asking each to build the same Android app in under 30 minutes. The writeup compares results and names which assistant the author would use again, adding to ongoing debate over which AI coding agent is most practical.

Google's Antigravity agentic coding platform has added support for Anthropic's Claude Opus 5.5 and Claude Sonnet 5.5, available to paid subscribers. The move expands the model choices developers can use for autonomous coding tasks inside the IDE, and the update is drawing attention as competition intensifies over AI-powered development tools.

Google has added Anthropic's Claude Opus 5.5 and Claude Sonnet 5.5 models to its Antigravity agentic coding platform, according to Fortune. The move gives developers using Antigravity a choice of rival AI models alongside Google's own Gemini models, underscoring how heavily Google is betting on openness to win over coders and compete with AI coding tools from Microsoft, OpenAI and others.

Google has added Anthropic's Claude 5.5 models to its Antigravity development platform, while simultaneously building anticipation for its upcoming Gemini 4 Argon models. The move signals Google's willingness to integrate rival AI models into its developer tools even as it promotes its own next-generation AI. Commenters are weighing what the dual announcement means for competition among major AI providers.
