Extract¶

Confirmed. The 'token tax' is well-documented in published research. A paper titled 'The Token Tax: Systematic Bias in Multilingual Tokenization' (arXiv, 2025) directly uses this term. Research shows Arabic requires approximately 3x more tokens than English for equivalent text. A doubling in tokens results in quadrupled training cost, and higher token fertility consistently predicts lower accuracy.
