DeepSeek has open-sourced DeepSeek-R1, a large language model fine-tuned using reinforcement learning to enhance reasoning capabilities. The model achieves results on par with OpenAI's o1 on benchmarks like MATH-500 and SWE-bench.
- Based on the mixture of experts DeepSeek-V3, it uses Group Relative Policy Optimization (GRPO) for training.
- The team addressed RL "cold start" issues by adding supervised fine-tuning with chain-of-thought examples before reinforcement learning.
- Distilled versions for Qwen and Llama were released, outperforming larger models like GPT-4 on math and coding tasks.
- DeepSeek-R1 ranked #3 overall in the LMArena shortly after release, leading in coding and math categories.
The open-source license permits using model outputs for distillation, potentially advancing the state of the art for language models of all sizes.
