## Episode Summary
Today's three headline stories — JetBrains' Mellum2 release, NVIDIA's Cosmos 3, and OpenAI's Michigan data center groundbreaking — share a common strategic skeleton: each is a lock-in play executed at a different layer of the AI stack. The open-versus-closed model debate is increasingly a distraction; the real competition is over which platforms own the deployment layer that models run on top of. A counter-narrative worth tracking: the efficiency and focus of today's specialized open-weight releases may quietly undermine the premise behind gigawatt-scale centralized compute.
