Inference is when an AI uses what it has already learned to answer a question, make a prediction, or complete a task.

Lesson #1: AI Foundations & the Agent Era
Think of it like…

Studying for a test is training. Taking the test is inference.

Everyday example

A weather app looks at today's weather data and predicts there's an 80% chance of rain tomorrow.

Construction example

An AI reviews project photos, schedules, weather, and crew availability to estimate when a remodeling project will be completed.

Business example

A bank's AI reviews information from a loan application and helps determine whether the applicant qualifies for financing.

Why this matters

Training builds the AI's knowledge. Inference is when that knowledge is put to work. Without inference, AI is simply information that never gets used.

One-sentence summary

Inference is the moment AI turns knowledge into action.

Try it yourself

Open your weather app and look at tomorrow's forecast — you just watched an inference happen. Name two more inferences you saw today.
