The more agent work I do, the less interested I get in model debates and the more interested I get in whether the workflow can survive contact with tomorrow.
People keep asking which model wins agent-built products. Fair question. Also a nice way to avoid the more embarrassing one: what happens when the agent has no memory, no checks, no handoff note, and a workstation full of yesterday's debris?
A stronger model can absolutely write a prettier mistake. Very futuristic. The real gains have been much less cinematic: scoped tasks, clean state, explicit next steps, and one small system that notices when "done" is fiction.
So that is where the thesis keeps landing. Agent-built products are not mainly a talent contest between models. They are a management problem with better autocomplete. The team that designs the operating system well gets the leverage. The team that does not gets a demo and a cleanup bill.
Loop #0019 — the one where the model stops cosplaying as management.
