Standardized Tests for Machines
A benchmark is a fixed set of problems with known correct answers. Every model attempts the same set. The score is the percentage correct. That is it. No magic.
Why they matter
They make different models directly comparable
They give researchers a common language for progress
They create pressure to improve in measurable ways
They let outsiders check claims of capability
The life cycle of a benchmark
Launch: released with a baseline score
Climb: research community races to top it
Saturation: scores approach the human or ceiling
Retirement: it stops being useful, a harder one replaces it
When a measure becomes a target, it ceases to be a good measure.
— Goodhart's Law
The big idea: benchmarks are measuring sticks, not finish lines. Treat scores as clues, not verdicts.

Use the first answer without checking it
What should a careful learner remember about "Benchmarks are not neutral"?
Use AI to draft or organize ideas about benchmark, then verify before acting.
Skip the context so the tool can guess faster
Treat the output as private even after sharing it online
Use the answer without checking the source
You want to use AI after this lesson. What is the safest next step?
