93 Subagents, 15,314 Model Calls: How Gemini 3.5 Flash Engineered and Booted a Custom OS Core

If you still view “Flash” models as simple, low-cost summary utilities, a recent research preview just destroyed that paradigm. By shifting the computational load from heavy-parameter models to massive hierarchical agent routing loops, a lightweight model just built a functional OS kernel from zero and booted Doom.

1. The Core Engineering Feat: System-Level Agent Synergy

Low-level programming—such as writing custom memory management kernels, hardware allocation drivers, and virtual filesystems—leaves absolutely zero room for code generation hallucination. A single off-by-one pointer error or unaligned memory...
