DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support learning (RL) to improve thinking capability. DeepSeek-R1 attains results on par with OpenAI's o1 model on several 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 design is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research study team also carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched numerous versions of each; these models surpass bigger models, including GPT-4, on mathematics and coding standards.

[DeepSeek-R1 is] the primary step toward enhancing language model reasoning capabilities utilizing pure reinforcement learning (RL). Our objective is to explore the capacity of LLMs to establish thinking capabilities without any monitored information, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a large variety of jobs, including imaginative writing, basic concern answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding efficiency on tasks needing long-context understanding, substantially outperforming DeepSeek-V3 on long-context criteria.

To develop the model, 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 design called DeepSeek-R1-Zero, which they have also released. This model displays strong reasoning efficiency, but" powerful thinking habits, it deals with several issues. For instance, DeepSeek-R1-Zero battles with difficulties like bad readability and language mixing."

To address this, the group utilized a brief stage of SFT to prevent 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 procedure assembled, they then gathered more SFT data utilizing rejection tasting, resulting in a dataset of 800k samples. This dataset was utilized for further fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek assessed their model on a range of reasoning, mathematics, and coding standards and compared it to other models, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined all of them on several of the criteria, consisting of AIME 2024 and MATH-500.

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

Django structure co-creator demo.qkseo.in Simon Willison composed about his experiments with one of the DeepSeek distilled Llama designs on his blog site:

Each reaction starts with a ... pseudo-XML tag containing the chain of idea used to help generate the reaction. [Given the prompt] "a joke about a pelican and a walrus who run a tea room together" ... It then thought for higgledy-piggledy.xyz 20 paragraphs before outputting the joke! ... [T] he joke is dreadful. But the process of arriving was such an intriguing insight into how these work.

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

DeepSeek is rapidly emerging as a strong home builder of open designs. Not only are these models great entertainers, however their license permits use of their outputs for distillation, potentially pressing forward the cutting-edge for language designs (and multimodal designs) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
