Multilingual Reasoning Cascades Need More Context

arXiv·medium signal

This arXiv paper (2026-06-25) shows that the standard translate-to-English, reason, translate-back cascade for multilingual reasoning is structurally lossy because each stage discards cultural grounding, register, and disambiguation cues. The authors propose a training-free 'context-aware translation cascade' that carries additional context across stages, improving multilingual reasoning without retraining. It's a cheap, immediately applicable intervention for practitioners shipping multilingual LLM pipelines.
