Humanity's Last Exam

The world's hardest pop quiz — written by about a thousand experts and designed to find out just how clever AI really is. Spoiler: the robots are sweating.
So… what is it, exactly?
Think of it as the final boss of AI tests. Here's the story in four easy bites.
The old tests got too easy
AI models started scoring 90%+ on popular quizzes like MMLU. When everyone gets an A+, the test stops telling you anything.
So the experts fought back
The Center for AI Safety and Scale AI asked professors and researchers worldwide to submit their nastiest questions — ones from the very edge of human knowledge.
Robots got to try first
If top AI models could already answer a question, it got tossed. Only the ones that stumped the machines made the cut.
No cheating allowed
Every question has one clear, checkable answer — but you can't find it with a quick web search. You actually have to know stuff.
A taste of the pain
The kinds of things it asks (paraphrased — the real ones are even scarier):
Proofs and puzzles that would make a maths professor reach for a second coffee.
Translate an ancient inscription that only a handful of scholars can read.
Name a tiny anatomical detail of a hummingbird most biologists have never studied.
Multi-step problems where one wrong assumption sends you to the wrong universe.
Why should I care?
📏 It's a ruler for progress
Researchers and policymakers use it to see how close AI is to expert-level knowledge.
🤥 It catches overconfidence
Early AI models scored low and were very sure of their wrong answers. Relatable, honestly.
🎓 "Last" ≠ end of AI
It's meant to be the last test of its kind — closed-ended, quiz-style — not the end of AI testing.
🧩 Acing it isn't everything
Passing a quiz isn't the same as doing new research or being creative. Humans: still needed!

Every few months the robots score a little higher. The day they ace Humanity's Last Exam, wearing a "humans are still smarter" tee gets a lot less convincing. Get yours while it's still (mostly) true.
