Light-R1
Light-R1 is an open source project focusing on long chain reasoning (Long COT), providing a training method from scratch through curriculum-based SFT, DPO and RL.
Product Details
Light-R1 is an open source project developed by Qihoo360 that aims to train long-chain inference models through curriculum-based supervised fine-tuning (SFT), direct preference optimization (DPO), and reinforcement learning (RL). This project achieves long-chain reasoning capabilities from scratch through decontaminated data sets and efficient training methods. Its main advantages include open source training data, low-cost training methods, and excellent performance in the field of mathematical reasoning. The project background is based on the current training needs of long-chain inference models and aims to provide a transparent and reproducible training method. The project is currently free and open source, suitable for use by research institutions and developers.
Main Features
How to Use
Target Users
The target audience includes artificial intelligence researchers, machine learning engineers, and developers interested in long-chain inference models. This project is suitable for research teams and enterprises who want to train high-performance long-chain inference models with limited resources, and also provides a valuable reference for the open source community.
Examples
Using the Light-R1-7B-DS model achieved an accuracy of 59.1% in the AIME24 test, significantly better than other similar models.
Through curriculum-based SFT and DPO training, Light-R1-32B achieves an accuracy of 76.6% on AIME24, surpassing DeepSeek-R1-Distill-Qwen-32B.
Developers can quickly reproduce the training process of Light-R1 and make customized improvements based on open source training codes and data sets.
