About OpenAI Evals
OpenAI Evals is a Python framework for systematically evaluating language models and LLM-based systems against benchmarks. It provides a registry of pre-built evaluation tasks and a structure for defining custom evaluation logic, enabling developers to measure model performance on specific capabilities.
Best for
Teams building LLM applications who need systematic, reproducible evaluation workflows
Use cases
- Comparing model outputs across different LLM versions or providers
- Measuring performance on domain-specific tasks before deployment
- Building custom evaluation suites for proprietary use cases
Notes
18,584 stars on GitHub. Last updated 2026-04-14.
Pros
