New research highlights English bias in LLMs, calls for per-language investment

A new paper reveals that large language models are significantly biased towards English, even when fine-tuned for other languages. Researchers found that continual pre-training does not improve cultural understanding in a target language cost-effectively compared to training from scratch. This suggests that future LLM development may require dedicated investment in per-language resources rather than solely expanding English-centric ones. AI

IMPACT Suggests a shift towards dedicated per-language LLM development, potentially increasing costs and complexity for non-English applications.

    Toward LLMs Beyond English-Centric Development

    Through an analysis of sequences generated by open-weight large language models (LLMs), we demonstrate that LLMs are heavily biased toward English. While continual pre-training is commonly used to adapt LLMs to a target language, we show that it does not offer a cost advantage ov…
