Summary

Google rebranded its Gemini CLI to Antigravity CLI, now routing Anthropic and OpenAI models under one subscription for seamless model switching in the terminal.

Gemini CLI is now **Antigravity CLI** — and with Google AI Pro, you can switch models directly from the terminal. Available models: Gemini 3.5 Flash, Gemini 3.1 Pro, Claude Sonnet 4.6, Claude Opus 4.6 (Thinking), and GPT-OSS 120B. The interesting part: Google is now routing Anthropic and OpenAI models through their own CLI under one subscription. Less "Google's AI tool", more "universal AI terminal built on Google infra." Tried it today — switching is seamless. Anyone else tested this?
