So after years of arguing over which model has the biggest brain, Nvidia discovers the real genius is basically good project management: memory, tools and a supervisor telling Claude to stop wandering into dead ends. Turns out AGI may just need a competent middle manager. … Somewhere, an enterprise architect is feeling extremely vindicated.

A harness is the software wrapper around an AI model — the tools, memory management, and rules that turn a raw model into something that can act on its own.

Just fyi
