Google Antigravity Built an OS (and more)
From the source
It was done using Gemini 3.5 Flash from a single prompt . This (a) goes to show just how intrinsically intelligent the Gemini family of models have gotten, even on Flash (Gemini 3.1 Pro was unable to do this), and (b) suggests that a much more economically feasible productionisation of agent teams is not that far away. At API pricing, building this OS would cost $916.92.
