HumanEvalPlus#

Overview#

HumanEval Plus is a rigorous extension of OpenAI’s HumanEval benchmark, designed to address high false-positive rates in code generation evaluation. It augments the original test cases with tens of thousands of automatically generated inputs to expose edge-case bugs and functional errors.

Task Description#

  • Task Type: Code Generation (Python)

  • Input: Function signature with docstring describing expected behavior

  • Output: Complete Python function implementation

  • Test Coverage: Massively expanded compared to original HumanEval

Key Features#

  • 164 problems from original HumanEval with enhanced test suites

  • Tens of thousands of additional test cases per problem

  • LLM-based and mutation-based test input generation

  • Exposes edge cases and bugs missed by original HumanEval

  • Much stricter and more accurate correctness evaluation

Evaluation Notes#

  • Default configuration uses 0-shot evaluation

  • Security Warning: By default, code is executed in the local environment. We strongly recommend using sandbox execution. See the sandbox documentation for details.

  • Supports pass@k metric calculation

  • Default timeout is 300 seconds to accommodate extensive test suites

  • Uses custom Docker image with numpy pre-installed
