Evaluation

Category: Fundamentals

“ee-val-yoo-AY-shun”

Testing an AI against known-good examples to measure how often it gets things right before you trust it.

Lesson #5: Trust, Risk & Running AI Responsibly →
Think of it like…

A road test before you hand someone the keys to the truck.

Everyday example

Asking a new AI ten questions you already know the answers to.

Construction example

Running an estimator AI on 20 past jobs and comparing to the real invoices.

Business example

Scoring a support bot on 100 real tickets before letting it reply to customers.

Why this matters

Without evaluation you're guessing, and you won't notice when an update makes things worse.

One-sentence summary

Evaluation is scoring an AI on known answers before trusting it.

Try it yourself

Build a 10-question test set for a task you'd hand to AI. Score it. Keep it for next time.
