DeepSeek-R1

1. Introduction

2. Model Summary

• We directly apply reinforcement learning (RL) to the base model without relying on supervised fine-tuning (SFT) as a preliminary step. This approach allows the model to explore chain-of-thought (CoT) for solving complex problems, resulting in the development of DeepSeek-R1-Zero. DeepSeek-R1-Zero demonstrates capabilities such as self-verification, reflection, and generating long CoTs, marking a significant milestone for the research community. Notably, it is the first open research to validate that reasoning capabilities of LLMs can be incentivized purely through RL, without the need for SFT. This breakthrough paves the way for future advancements in this area.
• We introduce our pipeline to develop DeepSeek-R1. The pipeline incorporates two RL stages aimed at discovering improved reasoning patterns and aligning with human preferences, as well as two SFT stages that serve as the seed for the model's reasoning and non-reasoning capabilities. We believe the pipeline will benefit the industry by creating better models.

• We demonstrate that the reasoning patterns of larger models can be distilled into smaller models, resulting in better performance compared to the reasoning patterns discovered through RL on small models. The open source DeepSeek-R1, as well as its API, will benefit the research community to distill better smaller models in the future.
• Using the reasoning data generated by DeepSeek-R1, we fine-tuned several dense models that are widely used in the research community. The evaluation results demonstrate that the distilled smaller dense models perform exceptionally well on benchmarks. We open-source distilled 1.5B, 7B, 8B, 14B, 32B, and 70B checkpoints based on Qwen2.5 and Llama3 series to the community.

• The distilled Qwen 1.5B consists of a tokenizer, embedding layer, a context model, iterator, a language model head and de tokenizer. We use 4-bit block wise quantization for the embeddings and language model head and run these memory-access heavy operations on the CPU. We focus the bulk of our NPU optimization efforts on the compute-heavy transformer block containing the context processing and token iteration, wherein we employ int4 per-channel quantization, and selective mixed precision for the weights alongside int16 activations. Details of the various precisions involved are in the table below, for additional clarity on the mix.
• While the Qwen 1.5B release from DeepSeek does have an int4 variant, it does not directly map to the NPU due to presence of dynamic input shapes and behavior – all of which needed optimizations to make compatible and extract the best efficiency. Additionally, we use the ONNX QDQ format to enable scaling across a variety of NPUs we have in the Windows ecosystem. We work out an optimal operator layout between the CPU and NPU for maximum power-efficiency and speed.

Usage Recommendations

1. Set the temperature within the range of 0.5-0.7 (0.6 is recommended) to prevent endless repetitions or incoherent outputs.
2. Avoid adding a system prompt; all instructions should be contained within the user prompt.
3. For mathematical problems, it is advisable to include a directive in your prompt such as: "Please reason step by step, and put your final answer within \boxed{}."
4. When evaluating model performance, it is recommended to conduct multiple tests and average the results.
