Alignment and safety

**Alignment** (in everyday AI talk) means making systems behave in line with intended human goals and constraints—not just maximizing a narrow score. **Safety** covers preventing harms from mistakes and misuse.

What it is

Alignment (in everyday AI talk) means making systems behave in line with intended human goals and constraints—not just maximizing a narrow score. Safety covers preventing harms from mistakes and misuse.

Why it matters

Labs publish safety policies and evaluations because models can be helpful *and* risky. You do not need conspiracy theories to care: scams, privacy leaks, and biased decisions are enough (Course 29).

How it works (plain)

Common layers:

  • Training data filters and policies
  • Post-training (instruction tuning, preference methods)
  • Product rules and refusals
  • Monitoring and abuse reporting
  • Human oversight for high-stakes actions

No layer is perfect. Defense in depth is the point.

Everyday example

A model refuses to provide bomb-making instructions but still helps with chemistry homework. Boundaries are designed—and sometimes bypassed (literacy without recipes: Course 29).

Try it

Read one lab’s published usage policy or model card and list three allowed uses and three disallowed uses in your own words.

Myths

⚠️ Myth: Safety filters mean the model is “censored into stupidity.”
✓ Reality: Products trade off capability, liability, and harm reduction; critique is fair, denial of tradeoffs is not.
⚠️ Myth: Alignment is only about sci-fi takeover.
✓ Reality: Much safety work is present-day misuse and reliability.
