DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to enhance thinking capability. DeepSeek-R1 attains results on par with OpenAI's o1 design on several criteria, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based on DeepSeek-V3, a mixture of specialists (MoE) model recently open-sourced by DeepSeek. This base design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented variation of RL. The research study group also carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and released several variations of each; these designs surpass bigger designs, consisting of GPT-4, on math and coding criteria.

[DeepSeek-R1 is] the first step towards improving language design thinking abilities using pure support knowing (RL). Our objective is to explore the capacity of LLMs to establish thinking abilities without any supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a large range of tasks, including creative writing, basic question answering, editing, summarization, wiki.dulovic.tech and more. Additionally, DeepSeek-R1 demonstrates outstanding efficiency on tasks requiring long-context understanding, significantly surpassing DeepSeek-V3 on long-context criteria.

To develop the model, DeepSeek started with DeepSeek-V3 as a base. They initially tried fine-tuning it just with RL, and with no supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have also released. This model shows strong thinking efficiency, but" powerful reasoning habits, it deals with several concerns. For circumstances, DeepSeek-R1-Zero fights with challenges like poor readability and language blending."

To resolve this, the group utilized a brief stage of SFT to avoid the "cold start" problem of RL. They gathered several thousand examples of chain-of-thought thinking to use in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then collected more SFT information using rejection sampling, resulting in a dataset of 800k samples. This dataset was used for further fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek examined their model on a variety of reasoning, mathematics, and coding benchmarks and compared it to other designs, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed all of them on numerous of the criteria, consisting of AIME 2024 and MATH-500.

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

co-creator Simon Willison discussed his experiments with among the DeepSeek distilled Llama models on his blog:

Each action begins with a ... pseudo-XML tag containing the chain of idea utilized to assist produce the reaction. [Given the timely] "a joke about a pelican and a walrus who run a tea room together" ... It then thought for 20 paragraphs before outputting the joke! ... [T] he joke is awful. But the process of arriving was such a fascinating insight into how these new models work.

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

DeepSeek is quickly emerging as a strong contractor of open models. Not just are these models fantastic entertainers, but their license permits use of their outputs for distillation, potentially pushing forward the cutting-edge for language designs (and multimodal models) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
