# jiwer vs qa_metrics

*GraphCanon updated Aug 8, 2026*

## Verdict

Pick jiwer if a Python library for assessing speech-to-text systems with word error rate measures; pick qa_metrics if qa_metrics is a Python library for evaluating LLMs using standardized QA and semantic metrics, including support for Black-box and open-source models along with APIs from OpenAI and Anthropic.

[jiwer](https://github.com/jitsi/jiwer) reports 917 GitHub stars, 107 forks, and 19 open issues, last pushed Apr 16, 2026. [qa_metrics](https://github.com/zli12321/qa_metrics) has 62 stars, 6 forks, and 0 open issues, last pushed Jul 18, 2025. Figures are from public GitHub metadata via [jiwer's repository](https://github.com/jitsi/jiwer) and [qa_metrics's repository](https://github.com/zli12321/qa_metrics).

## Choose when

### Choose jiwer if…

- License: jiwer is Apache-2.0, qa_metrics is MIT.
- Tags unique to jiwer: automatic-speech-recognition, evaluation-metrics, python3, speech-to-text.
- For accurate speech recognition evaluation needing direct WER calculations

### Choose qa_metrics if…

- License: qa_metrics is MIT, jiwer is Apache-2.0.
- Tags unique to qa_metrics: exact-matching, llm-evaluation, qa-automation-test.
- When you need to evaluate the performance of large language models with built-in standardized metrics like exact match and F1 Score.

## When NOT to use jiwer

- Avoid if your project requires only basic, non-word level performance indicators
- Not suitable for evaluating text-to-speech systems, as it focuses exclusively on speech-to-text output assessment

## When NOT to use qa_metrics

- Avoid if you seek advanced customization or fine-tuning options not present in qa_metrics for metric calculation methods beyond its provided set.
- Not ideal when needing specific evaluation tools that are not Black-box or open-source models, as the package focuses on these types of evaluations primarily.
