DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to improve 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 on DeepSeek-V3, a mixture of experts (MoE) model 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 group also carried out understanding distillation from DeepSeek-R1 to open-source Qwen and Llama designs and released several variations of each; these designs exceed bigger designs, consisting of GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the initial step toward improving language design reasoning capabilities utilizing pure reinforcement learning (RL). Our goal is to explore the capacity of LLMs to establish thinking abilities with no supervised data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a vast array of jobs, including imaginative writing, general question answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding efficiency on tasks needing long-context understanding, significantly exceeding DeepSeek-V3 on long-context benchmarks.

To establish the design, DeepSeek started with DeepSeek-V3 as a base. They first attempted fine-tuning it only with RL, and with no monitored fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have actually likewise released. This design shows strong thinking efficiency, but" powerful reasoning behaviors, it deals with several concerns. For example, DeepSeek-R1-Zero battles with difficulties like poor readability and language mixing."

To resolve this, the team utilized a short stage of SFT to avoid the "cold start" issue of RL. They gathered a number of thousand examples of chain-of-thought reasoning to use in SFT of DeepSeek-V3 before running RL. After the RL process assembled, they then collected more SFT information utilizing rejection tasting, resulting in a dataset of 800k samples. This dataset was utilized for further fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek assessed their design on a range of reasoning, math, and coding standards and compared it to other designs, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed all of them on several of the standards, yewiki.org consisting of AIME 2024 and MATH-500.

Within a few 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 also tied for # 1 with o1 in "Hard Prompt with Style Control" category.

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

Each reaction begins with a ... pseudo-XML tag containing the chain of idea utilized to assist produce the response. [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 horrible. But the process of was such an interesting insight into how these new designs work.

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

DeepSeek is rapidly emerging as a strong builder of open designs. Not only are these models terrific entertainers, but their license permits usage 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 models are available on HuggingFace.
