When the Harness Carries the Model
An open-weights model that fumbles tool calls on its own can go toe to toe with a frontier closed model — once you wrap the right error-handling around it. That gap, between what a model scores and what it does inside your repo, runs through everything we covered today.
Ahmad Awais on Latent Space describes "tool confusion" — open models repeating the same invalid tool call roughly fifty-six times per billion tokens — and Command Code's deterministic repair layer that patches malformed output instead of arguing with the model.
