Google launches Antigravity 2.0 platform, builds an OS in 12 hours

谷歌发布Antigravity 2.0平台，12小时构建操作系统

Google announced Antigravity 2.0 at I/O and demonstrated an agent building a runnable operating system from scratch in 12 hours, using 93 parallel sub-agents, more than 15,000 model calls, and 2.6 billion tokens, with API costs under $1,000.

Why it matters: HKR-H/K/R all pass: a Google I/O agent-platform release with concrete demo metrics. The post lacks availability, pricing, and replication details, so it lands in the lower 85–94 band.

Take

Google is showing an industrial-scale agent scheduler, not an operating-system breakthrough. The hard numbers are the story: 12 hours, 93 parallel sub-agents, 15,000-plus model calls, 2.6 billion tokens, and under $1,000 in API cost. That moves agentic coding away from clever single-session demos and into orchestration, caching, retries, and failure recovery. The claimed 12x speedup for Gemini 3.5 Flash on Antigravity points to the same bottleneck shift.

I don’t buy the “built an OS from scratch” framing yet. The snippet gives no test suite, hardware target, kernel scope, human-intervention rate, or failure distribution. Devin ran into the same wall last year: polished demos collapsed under real repos, acceptance tests, and rollback paths. Without a reproducible task bundle, Antigravity 2.0 looks like a very polished way to turn Gemini inference into a product narrative.
