LANG: Reinforcement Learning for Multilingual Reasoning with Language-Adaptive Hint Guidance

Multilingual reasoning in LLMs faces a persistent tension between maintaining input-language fidelity and preserving reasoning quality, with systems typically drifting toward English when prioritizing logic. LANG introduces a reinforcement learning framework that decouples these constraints through language-conditioned hints paired with adaptive scaffolding withdrawal and language-specific learning horizons. The approach matters because it expands RL-driven reasoning gains beyond English-dominant settings, addressing a real gap in how modern LLMs generalize across linguistic contexts. For teams building multilingual systems, this signals that reasoning enhancement no longer requires accepting language drift as inevitable.
