Prompt compression fails non-English languages, new paper finds

By PulseAugur Editorial · [1 sources] ·

A new paper titled "Lost in Compression: A Controlled Cross-Lingual Audit of Extractive Prompt Compressors" reveals that prompt compression techniques, designed to reduce LLM inference costs by removing low-information tokens, perform significantly worse on non-English languages compared to English. This disparity is attributed to English-centric training data for these compressors, leading to a substantial loss of contextual utility in other languages. The research suggests that multilingual training or a translate-then-compress approach could mitigate these issues, offering a more equitable cost-performance balance across languages. AI

IMPACT Prompt compression techniques may require multilingual training or alternative strategies to ensure equitable performance across languages, impacting LLM cost-efficiency.

    Lost in Compression: A Controlled Cross-Lingual Audit of Extractive Prompt Compressors

    Learned prompt compressors trained on English data disproportionately degrade non-English contexts, widening token-cost disparities, while multilingual training and deterministic methods reduce this gap.
