Microsoft just shipped a model that doesn't write a single word. Decision-1 scores fixed choices and returns a probability for each. Built for routing, classification, and agent control steps where you don't need generation, just a fast, confident yes/no. The "small model as control layer" pattern is quietly eating the agent stack.
