DeepSeek-R1 - An open-source deep reasoning model competing with OpenAI's o1 model.

## Introduction to DeepSeek-R1 DeepSeek-R1 is an open-source deep reasoning model developed by DeepSeek, designed to compete with OpenAI's o1 model. It excels in mathematical, coding, and reasoning tasks, particularly in Chinese writing, and supports a context length of up to 128K. ## Key Features of DeepSeek-R1 The key features of DeepSeek-R1 include: - Support for a context length of up to 128K, making it suitable for handling long documents and complex tasks. - Multiple versions available, including DeepSeek-R1-Zero and DeepSeek-R1, as well as six distilled models based on Qwen2.5 and Llama3, with parameters ranging from 1.5B to 70B. - High performance, with DeepSeek-R1-Distill-Qwen-32B outperforming OpenAI o1-mini in several benchmarks, especially in mathematical and coding tasks. ## Cost Comparison of DeepSeek-R1 and OpenAI's o1 Model DeepSeek-R1's API is priced at only 3.7% of the cost of OpenAI's o1 model, making it a highly cost-effective option for a wide range of applications. ## Unique Training Method of DeepSeek-R1-Zero DeepSeek-R1-Zero is trained entirely through reinforcement learning (RL) without using traditional supervised fine-tuning (SFT). This is the first time RL has been validated to independently incentivize the reasoning capabilities of large language models, potentially changing the paradigm for future model training. ## Accessing DeepSeek-R1 DeepSeek-R1 can be accessed through Hugging Face, where users can download models such as DeepSeek-R1 for local use. It is also available via API, which is cost-effective and suitable for commercial applications. Additionally, users can choose from various distilled models depending on their resource constraints. ### Citation sources: - [DeepSeek-R1](https://huggingface.co/deepseek-ai/DeepSeek-R1) - Official URL Updated: 2025-03-31
