What AI Does—and Does Not Do

Understand models as pattern-driven systems, not databases or people.

Core concept

By the end

You will be able to

  • Explain the difference between a model and a search database.
  • Recognize why confident output can still be wrong.
  • Choose when verification is required.
01

Models produce likely continuations

A language model learns patterns from large collections of examples. Given instructions and context, it generates a useful continuation one piece at a time.

That makes models excellent at explaining, transforming, drafting, classifying, and reasoning over supplied material. It does not make every output a stored fact.

02

Verification should match the stakes

Brainstorming can tolerate uncertainty. Medical, legal, financial, security, and production decisions require current authoritative evidence.

Good AI use combines a clear task, relevant context, constraints, and a way to verify the result.
