Did Google’s AI agents really build an operating system for $916?

Google recently launched its new model, Gemini 3.5 Flash, at the latest developer conference, alongside the Antigravity 2.0 application. The company claimed that a team of agents built a complete operating system with just one request, costing $900 in API fees. However, the assertion that it was a 'single' request is misleading, as it was revealed to consist of thousands of lines. The process involved a specialized framework with designated roles and delegation to sub-agents, raising questions about the effectiveness of this structure for other complex programming tasks.
