Very excited by the new suite of Antigravity products - in particularly can’t wait to see what folks build with our new SDK!

Antigravity + Gemini == 🔥🔥🔥
Just got off stage at I/O and we launched a lot but very excited to bring you all Antigravity 2.0 powered by Gemini 3.5 Flash. AGY 2.0 is our new app with a more powerful agent that can spin up subagents and even build an OS. 3.5 Flash is also more powerful than 3.1 Pro and runs at 800 tokens per second only on Antigravity.
This is a new way to build! Hope you all enjoy.

19/ Managed Agents in Gemini API is big.
Single API call → spin up an agent that reasons, uses tools, executes code in an isolated Linux environment.
Persistent environments, resumable state/files, custom instructions + markdown skills.
Yes, markdown skills. We are so back.
18/ Developer story: Antigravity is the center. New Antigravity 2.0 desktop app, CLI, SDK, Enterprise Agent Platform integration, scheduled tasks, dynamic subagents, and integrations across AI Studio, Android, Firebase.
We've optimized Gemini Flash to be 12x faster inside Antigravity.
Google literally said "your margin is my opportunity" 😂
12x faster!?
It's incredible to see how strongly Google coalesces around @antigravity! @_mohansolo is the 3rd person on the main keynote after Sundar and Demis! Antigravity 2.0 is expanding the agentic power, announcing a new SDK and CLI tools and Native voice support!
