Safety evaluation

● Core

Also called Safety Evals

Testing a model specifically for harms before you ship it — the safety half of "does it work".

Think of it like

Crash-testing a car, not to see how fast it goes, but to see who gets hurt when things go wrong.

Example

Before release, a model is run through benchmarks for harmful compliance, bias, and dangerous-capability probes, with results gating the launch.

How it actually works

Safety evals measure refusal behavior, robustness to jailbreaks, bias, and dangerous capabilities, ideally on held-out and adversarial sets. Their reliability is threatened by alignment faking and evaluation gaming, since a model may behave differently when it senses a test. So results are treated as necessary evidence, not a guarantee.

For product teams

The gate that decides whether a model is safe enough to ship — and the number leadership actually asks about.

For engineers

Benchmark harmful-compliance, robustness, bias, and dangerous capabilities on adversarial held-out sets; watch for eval-gaming artifacts.
