1. **[Do All Languages Cost the Same? Tokenization in the Era of Commercial Language Models](https://md.research.elamur.ai/free/en/papers/ahia-2023-do-all-languages-cost-same/)** *(2023 · 174 citations)* Commercial LM APIs bill per token, but how many tokens a text needs depends on the tokenizer and its training data.
2. **[MYTE: Morphology-Driven Byte Encoding for Better and Fairer Multilingual Language Modeling](https://md.research.elamur.ai/free/en/papers/limisiewicz-2024-myte-morphology-driven-byte-encoding/)** *(2024 · 30 citations)* Byte-level multilingual language models avoid the coverage gaps of subword vocabularies, but they inherit a bias built into UTF-8.
3. **[MAGNET: Improving the Multilingual Fairness of Language Models with Adaptive Gradient-Based Tokenization](https://md.research.elamur.ai/free/en/papers/ahia-2024-magnet-improving-multilingual-fairness-language/)** *(2024 · 19 citations)* Byte-level and subword language models usually split non-Latin-script text into many more pieces than English.
4. **[FLEXITOKENS: Flexible Tokenization for Evolving Language Models](https://md.research.elamur.ai/free/en/papers/owodunni-2026-flexitokens-flexible-tokenization-evolving-language/)** *(2026 · 3 citations)* Subword tokenizers stay fixed when a language model is finetuned. As a result, text from new domains, unseen languages or unfamiliar scripts gets split into too many pieces, which hurts accuracy and inflates compute costs. Byte-level models with a learned segmentation module are meant to fix this. In practice…
