GRPO effectiveness studied in non-English and multilingual AI reasoning

A new study published on arXiv explores the effectiveness of Group Relative Policy Optimization (GRPO) in non-English and multilingual settings for improving language model reasoning. Researchers found that training models to reason in their native languages results in performance close to English-based training, with significant cross-lingual transfer observed. However, the study also highlights that specific trends are highly dependent on the model and language, and training in one language can sometimes lead to regressions in others, underscoring the need for broad evaluation.

IMPACT This research suggests that AI reasoning capabilities can be effectively developed beyond English, potentially broadening access and applicability of advanced language models globally.

    GRPO Beyond English: A Large-Scale Study of GRPO in Non-English and Multilingual Settings

    arXiv:2608.13698v1 Announce Type: new Abstract: Reinforcement Learning with Verifiable Rewards (RLVR), often optimized with Group Relative Policy Optimization (GRPO), has become a central recipe for improving the reasoning capabilities of pretrained language models but current st…
