DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support knowing (RL) to improve reasoning capability. DeepSeek-R1 attains results on par with OpenAI's o1 model on numerous criteria, including MATH-500 and SWE-bench.

DeepSeek-R1 is based on DeepSeek-V3, a mixture of specialists (MoE) design recently open-sourced by DeepSeek. This base model is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research group also carried out understanding distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched several versions of each; these designs outshine bigger models, including GPT-4, on math and coding standards.

[DeepSeek-R1 is] the primary step towards enhancing language design thinking capabilities utilizing pure reinforcement knowing (RL). Our goal is to explore the potential of LLMs to establish thinking capabilities without any monitored data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a vast array of jobs, including innovative writing, basic question answering, editing, summarization, and more. Additionally, DeepSeek-R1 shows exceptional efficiency on jobs needing long-context understanding, considerably outperforming DeepSeek-V3 on long-context standards.

To establish the model, DeepSeek started with DeepSeek-V3 as a base. They initially tried fine-tuning it just with RL, and with no monitored fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have actually likewise released. This model shows strong thinking performance, but" powerful thinking behaviors, it deals with numerous concerns. For instance, DeepSeek-R1-Zero battles with challenges like poor readability and language blending."

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

DeepSeek examined their model on a range of reasoning, mathematics, and coding standards and compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined all of them on several of the benchmarks, 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" classification.

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

Each response starts with a ... pseudo-XML tag containing the chain of thought used to help produce the reaction. [Given the prompt] "a joke about a pelican and a walrus who run a tea room together" ... It then believed 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 new models work.

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

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

The DeepSeek-R1 designs are available on HuggingFace.
