Decision brief

simple-evals provides lightweight tools for evaluating language models using reference implementations from HealthBench, BrowseComp, SimpleQA. Last updates July 2025.

Good fit when

  • When you need a stable baseline to evaluate model performance with specific benchmarks like MMLU, HumanEval, and DROP that won't change after July 2025
  • If your project relies on the exact benchmark results for models evaluated in the repository from June 2024 to July 2025

Avoid when

  • For evaluating models released or significantly updated after July 2025, as this tool does not include future benchmarks
  • When you need a tool that will adapt and expand its benchmark set with emerging model releases and evaluation tasks beyond 2025
