Gemini 4 Argon is here! It is our frontier model built for complex workflows across real-world software engineering, tested across Google's own codebases on real production challenges. There, we have seen an improvement in both developer velocity, with a 35% increase in agentic code, and code quality, with a 30% decrease in post-submit rollbacks. Rolling out now to Google AI Ultra subscribers, try it in the Antigravity app and the Antigravity CLI. Get inspired with what you can build today ↓

Real-time animation, generative audio, and custom tool-building powered exclusively by code.

We’re rolling out Gemini 4 Argon in Antigravity to paid Google AI Pro subscribers today. Demand has been incredible and we've scaled capacity deliberately to get here. We’ve rolled out a separate weekly-only Argon quota for Pro on top of the existing Gemini bucket for 3.8 Flash so you have the best of Gemini for all your tasks.

Machine translation often sounds mechanical, while manual translation across 100+ pages can take weeks. Here’s how the Antigravity team used Gemini 4 Argon and multi-agent workflows in Google Antigravity to calibrate natural translations across 17 languages in two days.

Watch how Antigravity takes an Android app from prompt to real device. Using the Stitch MCP and the Android CLI plugin, the agent pulls your designs, builds the native Jetpack Compose components, verifies them in the emulator, and runs the final build on a real phone.

Antigravity 2.0 now features a dedicated planning mode, just like the Antigravity CLI. Type /plan and the agent steps back to think through the task, and conduct extensive research, before generating an implementation plan for your review. The agent will ask for your approval before it begins executing on the task. You can also ask for a plan naturally in your prompt, for a lighter version of a plan.
