DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support knowing (RL) to enhance reasoning ability. DeepSeek-R1 attains outcomes on par with o1 design on several criteria, including MATH-500 and hb9lc.org SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mix of experts (MoE) model just recently open-sourced by DeepSeek. This base model is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented variant of RL. The research group also carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and released a number of variations of each; these designs surpass larger designs, consisting of GPT-4, on mathematics and coding standards.

[DeepSeek-R1 is] the primary step towards enhancing language design thinking capabilities using pure support learning (RL). Our objective is to check out the capacity of LLMs to establish reasoning abilities with no supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a vast array of tasks, including creative writing, general 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 benchmarks.

To develop the design, DeepSeek began with DeepSeek-V3 as a base. They first tried fine-tuning it only with RL, and with no supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have likewise released. This model displays strong thinking performance, but" effective thinking behaviors, it deals with several issues. For instance, DeepSeek-R1-Zero has problem with obstacles like bad readability and language blending."

To resolve this, the group used a brief stage of SFT to prevent the "cold start" problem of RL. They gathered several thousand examples of chain-of-thought reasoning to use in SFT of DeepSeek-V3 before running RL. After the RL procedure converged, they then collected more SFT data using rejection sampling, resulting in a dataset of 800k samples. This dataset was used for additional fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek examined their design 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 outperformed all of them on several of the benchmarks, including AIME 2024 and MATH-500.

Within a couple of days of its release, the LMArena announced that DeepSeek-R1 was ranked # 3 general in the arena and # 1 in coding and mathematics. It was also tied for # 1 with o1 in "Hard Prompt with Style Control" classification.

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

Each response begins with a ... pseudo-XML tag containing the chain of idea utilized to help create the reaction. [Given the timely] "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 getting there 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 builder of open designs. Not just are these models excellent entertainers, however their license permits use of their outputs for distillation, possibly pressing forward the state of the art for language designs (and multimodal designs) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
