Recent evidence shows that some non-English languages can outperform English on reasoning benchmarks. This paper asks how much accuracy could be gained by having a model reason over the same question in many languages and pooling the results. 2. **[ExpLang: Improved Exploration and Exploitation in LLM Reasoning with On-Policy Thinking Language Selection](https://md.research.elamur.ai/free/en/papers/gao-2026-explang-improved-exploration-exploitation-llm/)** *(2026 · 4 citations)* Reasoning models are usually post-trained with RL to think in English, even though sampling chains of thought in several languages can yield more varied solutions and higher Pass@k. ExpLang turns the choice of thinking language into an action the model takes itself during RL.
