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

DeepSeek-R1 is based on DeepSeek-V3, a mix 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 also performed understanding distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched numerous versions of each; these designs outshine larger models, consisting of GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the initial step toward enhancing language model reasoning capabilities utilizing pure reinforcement knowing (RL). Our goal is to check out the potential of LLMs to establish thinking capabilities without any supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a wide variety of tasks, including imaginative writing, basic question answering, editing, summarization, and more. Additionally, DeepSeek-R1 shows outstanding performance on jobs needing long-context understanding, considerably exceeding DeepSeek-V3 on long-context benchmarks.

To establish the design, DeepSeek started with DeepSeek-V3 as a base. They first tried fine-tuning it just with RL, and with no monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have actually also launched. This design shows strong thinking performance, however" powerful thinking habits, it faces numerous problems. For example, DeepSeek-R1-Zero struggles with challenges like poor readability and language mixing."

To address this, the team used a brief stage of SFT to avoid the "cold start" issue of RL. They gathered numerous thousand examples of chain-of-thought reasoning to use in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then gathered more SFT data using rejection sampling, leading to a dataset of 800k samples. This dataset was utilized for more fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek evaluated their design on a range of reasoning, math, and coding criteria and compared it to other designs, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined all of them on numerous 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 total in the arena and # 1 in coding and math. It was also connected for # 1 with o1 in "Hard Prompt with Style Control" category.

Django structure co-creator Simon Willison discussed his explores one of the DeepSeek distilled Llama models on his blog site:

Each reaction starts with a ... pseudo-XML tag containing the chain of idea used to help create 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 dreadful. But the process of arriving was such an intriguing insight into how these brand-new models work.

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

DeepSeek is rapidly becoming a strong contractor of open models. Not just are these models terrific entertainers, but their license allows usage of their outputs for distillation, potentially pressing forward the state of the art for language models (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
