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

DeepSeek-R1 is based on DeepSeek-V3, a mix of specialists (MoE) model just recently open-sourced by DeepSeek. This base model is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research group likewise carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and released numerous versions of each; these designs outshine bigger models, including GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the primary step towards enhancing language model thinking capabilities utilizing pure support learning (RL). Our objective is to check out the capacity of LLMs to develop reasoning capabilities with no supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a vast array of jobs, consisting of innovative writing, basic concern answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates impressive performance on tasks needing long-context understanding, significantly DeepSeek-V3 on long-context criteria.

To establish the model, DeepSeek began with DeepSeek-V3 as a base. They first attempted fine-tuning it just with RL, and without any supervised fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have actually also launched. This model exhibits strong reasoning efficiency, but" effective thinking behaviors, it faces several problems. For example, DeepSeek-R1-Zero battles with difficulties like poor readability and language blending."

To resolve this, the team used a brief phase of SFT to prevent the "cold start" problem of RL. They gathered several thousand examples of chain-of-thought reasoning to utilize in SFT of DeepSeek-V3 before running RL. After the RL procedure converged, they then collected 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 variety of thinking, math, and coding criteria and compared it to other models, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed all of them on numerous of the standards, 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 math. It was likewise connected for # 1 with o1 in "Hard Prompt with Style Control" category.

Django structure co-creator Simon Willison discussed his try outs among the DeepSeek distilled Llama models on his blog:

Each reaction begins with a ... pseudo-XML tag containing the chain of thought used to help create the action. [Given the prompt] "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 dreadful. But the process of arriving was such an interesting insight into how these brand-new designs work.

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

DeepSeek is rapidly emerging as a strong contractor of open models. Not just are these models fantastic entertainers, however their license allows use of their outputs for distillation, possibly pushing forward the state of the art for language designs (and multimodal designs) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
