Large language models (LLMs) have made significant progress in language generation, but their reasoning skills remain insufficient for complex problem-solving. Tasks such as mathematics, coding, and scientific questions continue to pose a significant challenge. Enhancing LLMs’ reasoning abilities is crucial for advancing their capabilities beyond simple text generation. The key challenge lies in integrating advanced learning techniques with effective inference strategies to address these reasoning deficiencies. Introducing OpenR Researchers from University College London, the University of Liverpool, Shanghai Jiao Tong University, The Hong Kong University of Science and Technology (Guangzhou), and Westlake University introduce OpenR, an open-source framework that integrates
