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

DeepSeek-R1 is based on DeepSeek-V3, a mixture of experts (MoE) model just recently open-sourced by DeepSeek. This base design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented variant of RL. The research team likewise carried out understanding distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched a number of versions of each; these designs surpass larger models, including GPT-4, 89u89.com on mathematics and .

[DeepSeek-R1 is] the first step toward improving language model reasoning capabilities using pure support learning (RL). Our goal is to explore the potential of LLMs to establish thinking capabilities with no supervised information, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a wide variety of jobs, including creative writing, basic question answering, editing, summarization, and more. Additionally, DeepSeek-R1 shows exceptional performance on jobs requiring long-context understanding, substantially exceeding DeepSeek-V3 on long-context criteria.

To develop the model, DeepSeek began with DeepSeek-V3 as a base. They first tried fine-tuning it just with RL, and with no monitored fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have likewise launched. This design shows strong reasoning performance, however" powerful reasoning behaviors, it faces numerous problems. For circumstances, DeepSeek-R1-Zero battles with difficulties like poor readability and language mixing."

To address this, the team utilized a short stage of SFT to avoid the "cold start" problem of RL. They gathered a number of thousand examples of chain-of-thought thinking to use in SFT of DeepSeek-V3 before running RL. After the RL procedure assembled, they then collected more SFT data using rejection sampling, resulting in a dataset of 800k samples. This dataset was used for further fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek assessed their model on a variety of thinking, math, and coding benchmarks and compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 surpassed 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 total in the arena and # 1 in coding and mathematics. It was also connected for # 1 with o1 in "Hard Prompt with Style Control" category.

Django structure co-creator Simon Willison discussed his experiments with one of the DeepSeek distilled Llama designs on his blog:

Each action begins with a ... pseudo-XML tag containing the chain of thought used to assist generate the action. [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 terrible. But the process of arriving was such an interesting insight into how these brand-new designs work.

Andrew Ng's newsletter The Batch discussed DeepSeek-R1:

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

The DeepSeek-R1 designs are available on HuggingFace.
