DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to enhance reasoning ability. DeepSeek-R1 attains outcomes on par with OpenAI's o1 model on a number of standards, including MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mixture of experts (MoE) design just recently open-sourced by DeepSeek. This base model is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented variation of RL. The research study team likewise carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched numerous variations of each; these designs outperform larger designs, including GPT-4, on mathematics and coding standards.

[DeepSeek-R1 is] the initial step towards enhancing language model thinking capabilities using pure reinforcement learning (RL). Our goal is to explore the potential of LLMs to develop thinking abilities with no supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of jobs, including creative writing, general concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional performance on tasks requiring long-context understanding, considerably outshining DeepSeek-V3 on long-context benchmarks.

To develop the design, DeepSeek began with DeepSeek-V3 as a base. They first tried fine-tuning it just with RL, and without any supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have also released. This model shows strong reasoning performance, but" powerful reasoning behaviors, it deals with several concerns. For circumstances, DeepSeek-R1-Zero deals with difficulties like bad readability and language blending."

To address this, the team used a short stage of SFT to prevent the "cold start" issue of RL. They collected a number of thousand examples of chain-of-thought reasoning to utilize in SFT of DeepSeek-V3 before running RL. After the RL procedure assembled, they then gathered more SFT information using rejection tasting, resulting in a dataset of 800k samples. This dataset was utilized for additional fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek assessed their design on a range of thinking, math, and coding standards and setiathome.berkeley.edu compared it to other designs, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 surpassed all of them on several of the standards, consisting of AIME 2024 and MATH-500.

Within a couple of days of its release, the LMArena revealed that DeepSeek-R1 was ranked # 3 overall in the arena and # 1 in coding and math. It was likewise connected for # 1 with o1 in "Hard Prompt with Style Control" category.

Django framework co-creator Simon Willison blogged about his try outs among the DeepSeek distilled Llama models on his blog:

Each reaction begins with a ... 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 believed for 20 paragraphs before outputting the joke! ... [T] he joke is terrible. But the process of getting there was such a fascinating insight into how these brand-new models work.

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

DeepSeek is quickly emerging as a strong home builder of open designs. Not only are these models terrific entertainers, however their license allows usage of their outputs for distillation, potentially pushing forward the state of the art for language designs (and multimodal designs) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
