Was passiert ist: tokenizers v1: encode, decode and scaling, measured

Hugging Face released tokenizers v1 release candidate, achieving 3 to 30 times faster encoding than v0.23 while maintaining identical output.

Warum es zählt: tokenizers v1: encode, decode and scaling, measured

Matters for engineers processing large datasets, serving many concurrent requests, or repeatedly tokenizing long inputs where tokenization becomes a bottleneck.

Achtung: tokenizers v1: encode, decode and scaling, measured

Performance gains vary by model family; some patterns use regex fallback. Python bindings add per-call overhead not measured in benchmarks. API unchanged but requires new build.
