DeepSeek-R1, an LLM fine-tuned with support learning (RL) to improve reasoning capability. DeepSeek-R1 attains results on par with OpenAI's o1 design on numerous criteria, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mixture of specialists (MoE) design just recently open-sourced by DeepSeek. This base design is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research team likewise carried out understanding distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched several versions of each; these designs outshine bigger models, consisting of GPT-4, on math and coding benchmarks.

[DeepSeek-R1 is] the primary step toward enhancing language design reasoning capabilities using pure reinforcement knowing (RL). Our goal is to explore the capacity of LLMs to develop thinking abilities without any supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a vast array of tasks, consisting of creative writing, basic question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 shows outstanding performance on jobs needing long-context understanding, considerably surpassing DeepSeek-V3 on long-context criteria.

To develop the design, DeepSeek began with DeepSeek-V3 as a base. They first attempted fine-tuning it only with RL, and without any monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have also released. This model exhibits strong thinking efficiency, however" powerful reasoning behaviors, it deals with several issues. For circumstances, DeepSeek-R1-Zero deals with challenges like poor readability and language blending."

To address this, the group utilized a brief stage of SFT to prevent the "cold start" issue of RL. They gathered a number of thousand examples of chain-of-thought thinking to utilize in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then gathered more SFT information using rejection sampling, leading to a dataset of 800k samples. This dataset was used for further fine-tuning and to produce the distilled models from Llama and forum.batman.gainedge.org Qwen.

DeepSeek assessed their model on a range of reasoning, math, and coding benchmarks and compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined all of them on several of the benchmarks, consisting of AIME 2024 and MATH-500.

Within a few days of its release, the LMArena announced that DeepSeek-R1 was ranked # 3 overall in the arena and # 1 in coding and math. It was also tied for # 1 with o1 in "Hard Prompt with Style Control" classification.

Django structure co-creator Simon Willison composed about his experiments with among the DeepSeek distilled Llama designs on his blog:

Each response begins with a ... pseudo-XML tag containing the chain of thought utilized to help generate the response. [Given the timely] "a joke about a pelican and a walrus who run a tea space together" ... It then thought for 20 paragraphs before outputting the joke! ... [T] he joke is dreadful. But the process of arriving was such a fascinating insight into how these new designs work.

Andrew Ng's newsletter The Batch blogged about DeepSeek-R1:

DeepSeek is rapidly becoming a strong contractor of open models. Not only are these designs terrific entertainers, however their license allows use of their outputs for distillation, possibly pushing forward the state of the art for language models (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
