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

Sandbox Configuration

This benchmark requires a sandbox environment for code execution.

{
  "image": "python3.11-numpy",
  "tools_config": {
    "shell_executor": {},
    "python_executor": {}
  }
}

Usage

Using CLI

evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets humaneval_plus \
    --sandbox '{"enabled": true}' \
    --limit 10  # Remove this line for formal evaluation

Using Python

from evalscope import run_task
from evalscope.config import TaskConfig

task_cfg = TaskConfig(
    model='YOUR_MODEL',
    api_url='OPENAI_API_COMPAT_URL',
    api_key='EMPTY_TOKEN',
    datasets=['humaneval_plus'],
    sandbox={'enabled': True},
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
