DeepSeek R1's recipe to replicate o1 and the future of reasoning LMs

DeepSeek AI has launched its first reasoning language model, R1, which is trained through a four-stage reinforcement learning (RL) process. This model is significant as it is MIT-licensed, allowing researchers and companies to build upon it. The training process includes a "cold-start" phase using supervised fine-tuning on synthetic data, followed by large-scale RL training, and a mix of reasoning and general queries to transition to a general-purpose model. The release of R1 marks a pivotal moment in reasoning model research, which has previously lacked a clear foundational paper. The pricing of R1 is notably lower than that of OpenAI's o1 model, indicating a potential price war in the reasoning model market. While OpenAI's o3 model may be technically superior, it is not yet widely available. The R1 model's training emphasizes the importance of a strong base model and the effectiveness of RL in enhancing reasoning capabilities. The training methodology includes accuracy, format, and language consistency rewards, which are crucial for developing a stable and effective model. Overall, the advancements in R1 suggest a promising future for reasoning language models, with expectations of significant progress in the coming years.
