LLMs show bias toward Latin script in multilingual writing systems

By PulseAugur Editorial · [2 sources] ·

Researchers have investigated how large language models handle languages written in multiple scripts, finding that models often route information through shared latent representations. Their analysis revealed that scripts for the same language become more separable across model layers, and a simple directional input can change the output script while preserving meaning. The study also identified specific attention heads that mediate script choice, suggesting these mechanisms are language-agnostic and exhibit a bias towards Latin script. AI

IMPACT Reveals potential biases in LLMs' handling of multilingual text, impacting global content generation and translation.
