The Limits of BPE Tokenization in Polish: Segmentation-Flexional Forms, Grammatical Anchoring, and First-Person Stability in Inflectional Language Models

What changed

Research demonstrates that BPE tokenization in Polish stabilizes frequent surface fragments rather than grammatical categories or stable first-person speaker grounding.

Why you should care

Frequency-based tokenization methods face inherent structural limits when applied to highly inflectional languages like Polish.

Your move

Watch. Monitor for alternative sublexical stabilization techniques that better preserve grammatical structure.
