The post introduces Decision Models, a new category that skips lengthy text generation and instead picks from predefined options—handling classification, routing, prioritization, verification, workflow control, and agent orchestration with fast, structured answers apps can consume directly (e.g., routing a ticket to Sales/Support/Billing).
