M38.5 CONNECT THE MECHANISM
Build a router that knows when to ask
Tally gets 20,000 messages a day and a model that gives a probability for every route. Set a gate on the top probability, compare thresholds in dollars, and send the unsure cases to people or a slower model.

Lesson overview
Tally gets 20,000 messages a day and a model that gives a probability for every route. Set a gate on the top probability, compare thresholds in dollars, and send the unsure cases to people or a slower model.
What you’ll explore
- A decision model's probabilities let code choose when to act. A threshold on the top probability trades automation rate against the errors among automated messages, a cascade sends uncertain cases to a costlier model, fan-out asks several small questions in one call, and audits and slice monitoring catch drift that the gate cannot see.
