How It Works
Similar to MMLU but with 10 answer choices per question and harder questions that require multi-step reasoning. The increased number of options makes random guessing far less effective (10% vs 25% baseline).
Why It Matters
As models began saturating the original MMLU benchmark, MMLU-Pro was created to better differentiate between top-performing models. It provides a more reliable signal of genuine understanding.
Limitations
Still relies on multiple-choice format. Being newer, it has less historical data for trend analysis. Some questions may still be solvable through pattern matching rather than true understanding.
