Understanding the Benchmarks

SWE-bench Verified

Tests AI models on real-world GitHub issues from popular open-source projects. Models must understand code, identify bugs, and generate correct fixes. The "Verified" subset contains 500 carefully validated issues.

HumanEval

Hand-written programming problems that evaluate code generation from natural language descriptions. Each problem includes test cases to verify functional correctness.

GPQA Diamond

Graduate-level questions in physics, biology, and chemistry. Designed to be difficult enough that even PhD holders need to research before answering.

MMLU

57 subjects covering elementary mathematics to advanced law. Tests world knowledge and problem-solving ability across diverse domains.
