OpenR: A New Framework for Boosting Large Language Model Reasoning Abilities
London, UK – A collaborative effort between leading universities, including University College London (UCL), Shanghai Jiao Tong University, the University of Liverpool, Hong Kong University of Science and Technology (Guangzhou), and Westlake University, has resulted in the developmentof OpenR, an open-source framework designed to enhance the reasoning capabilities of large language models (LLMs).
Inspired by OpenAI’s o1model, OpenR leverages the power of search, reinforcement learning, and process supervision to significantly improve LLM reasoning skills. This framework is the first of its kind to offer an open-source implementation of integrated technologies, enabling LLMs toachieve advanced reasoning through efficient data acquisition, training, and inference pathways.
Key Features of OpenR:
- Integrated Training and Inference: OpenR seamlessly integrates data acquisition, reinforcement learning training (both online and offline), and non-autoregressive decoding into a unified platform.
- Process Reward Model (PRM): This model enhances LLM strategies during training through policy optimization techniques, guiding the LLM’s search process during decoding.
- Reinforcement Learning Environment: Mathematical problems are modeled as Markov Decision Processes (MDPs),allowing for the optimization of model strategies using reinforcement learning methods.
- Multi-Strategy Search and Decoding: OpenR supports a variety of search algorithms, including Beam Search and Best-First Search, enabling diverse and flexible decoding strategies.
OpenR’s unique approach addresses several challenges in LLM reasoning:
- Data Acquisition: An automated data pipeline extracts reasoning steps from result labels, minimizing manual annotation efforts while ensuring valuable inference information is collected.
- Training and Inference Efficiency: The framework integrates training and inference processes, enabling efficient and effective model optimization.
- Scalability: OpenR adheres to the test-time augmentation principle, allowing models to generate or search for refined outputs during testing.
The development of OpenR signifies a significant step forward in advancing LLM reasoning abilities. By providing a comprehensive and open-source framework, OpenR empowers researchers and developers to explore new frontiers in AI, paving the way formore sophisticated and capable language models.
