DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support learning (RL) to improve reasoning capability. DeepSeek-R1 attains results on par with OpenAI's o1 model on a number of benchmarks, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based on DeepSeek-V3, a mixture of specialists (MoE) design just recently open-sourced by DeepSeek. This base model is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented variation of RL. The research group also performed knowledge 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 math and coding benchmarks.

[DeepSeek-R1 is] the initial step toward improving language design thinking capabilities utilizing pure reinforcement knowing (RL). Our objective is to check out the potential of LLMs to establish thinking capabilities without any supervised data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of tasks, consisting of creative writing, basic concern answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional efficiency on jobs requiring long-context understanding, substantially exceeding DeepSeek-V3 on long-context criteria.

To develop the design, DeepSeek began with DeepSeek-V3 as a base. They first attempted fine-tuning it just with RL, and with no supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have actually also launched. This model shows strong reasoning performance, but" powerful reasoning behaviors, it deals with a number of concerns. For instance, DeepSeek-R1-Zero has problem with difficulties like bad readability and language blending."

To address this, the team used a brief phase of SFT to avoid the "cold start" issue of RL. They gathered a number of thousand examples of chain-of-thought thinking to use in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then collected more SFT data utilizing rejection tasting, resulting in a dataset of 800k samples. This dataset was used for wiki.myamens.com further fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek examined their design on a variety of thinking, mathematics, and coding criteria and compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 surpassed all of them on numerous of the standards, 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 likewise tied for # 1 with o1 in "Hard Prompt with Style Control" classification.

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

Each reaction starts with a ... pseudo-XML tag containing the chain of idea utilized to help produce the action. [Given the timely] "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 awful. But the process of getting there was such a fascinating insight into how these brand-new designs work.

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

DeepSeek is quickly becoming a strong home builder of open models. Not only are these models fantastic 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 designs are available on HuggingFace.
