- What happened
- TokEval is a framework for evaluating language model tokenizers using metrics beyond compression rate, including UTF-8 integrity and digit alignment.
- Why it matters
- Matters for engineers selecting tokenizers for pretraining, especially those optimizing for math, code, or linguistic tasks.
- Watch out
- Framework shows correlations in controlled experiments but may not predict performance across all model scales, architectures, or deployment contexts.
