Google demonstrates its Antigravity 2.0 multi-agent system powered by Gemini 3.5 Flash by directing it to build a functioning operating system from scratch using 93 parallel sub-agents

Google's Antigravity 2.0 built the core framework of a working operating system in 12 hours, spinning up 93 sub-agents and processing billions of tokens for under $1,000 in compute costs. On stage, the team booted Doom on the AI-built OS. Just imagine all the possibilities in the future!
