When to add a real model

Read first Task 34

A keyword bot is free, predictable and enough for a small FAQ. Move to a hosted model when the volume and the variety of questions outgrow the dictionary — not before.

Definition and example

When to add a real model is the focus of this lesson. A keyword bot is free, predictable and enough for a small FAQ. Move to a hosted model when the volume and the variety of questions outgrow the dictionary — not before. The task asks you to apply that idea in a small example: When is a real model worth the cost. Before you run the code, predict what should happen. Then Inspect the printed output and the values your program uses and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
