Google Antigravity 2.0 Review: The AI Agent Platform That Built an OS in 12 Hours — HyzenPro article cover

Google just raised the bar for what an AI development platform can do — and it did it live on stage at Google I/O 2026. The star of the show was Google Antigravity 2.0, a brand-new standalone desktop app built from the ground up to orchestrate multiple autonomous AI agents working in parallel.

To prove it, Google's team used Antigravity 2.0 and Gemini 3.5 Flash to build a functioning operating system from scratch in under 12 hours — 93 parallel sub-agents, 2.6 billion tokens, all for less than $1,000 in API credits. Then they ran Doom on it.
