DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to enhance thinking ability. DeepSeek-R1 attains results on par with OpenAI's o1 design on a number of criteria, including MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mixture of professionals (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 study team also performed understanding distillation from DeepSeek-R1 to open-source Qwen and Llama designs and released numerous variations of each; these models outperform larger models, including GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the initial step towards enhancing language design reasoning capabilities utilizing pure reinforcement knowing (RL). Our objective is to check out the capacity of LLMs to establish reasoning capabilities without any monitored data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a vast array of tasks, consisting of imaginative writing, basic question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 shows outstanding efficiency on jobs requiring long-context understanding, substantially outperforming DeepSeek-V3 on long-context criteria.

To establish the design, DeepSeek began with DeepSeek-V3 as a base. They initially tried fine-tuning it just with RL, and without any monitored fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have also released. This design exhibits strong reasoning efficiency, however" powerful thinking behaviors, it deals with several issues. For example, DeepSeek-R1-Zero fights with difficulties like poor readability and language mixing."

To address this, the group used a brief phase of SFT to prevent the "cold start" problem 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 collected more SFT information using rejection tasting, resulting in a dataset of 800k samples. This dataset was used for additional fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek evaluated their design on a variety of reasoning, mathematics, and coding standards and compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 surpassed all of them on several of the standards, including 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 also tied for larsaluarna.se # 1 with o1 in "Hard Prompt with Style Control" category.

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

Each action starts with a ... pseudo-XML tag containing the chain of thought used to assist produce the response. [Given the timely] "a joke about a pelican and a walrus who run a tea room together" ... It then thought for 20 paragraphs before outputting the joke! ... [T] he joke is horrible. But the process of arriving was such a fascinating insight into how these new models work.

Andrew Ng's newsletter The Batch discussed DeepSeek-R1:

DeepSeek is rapidly becoming a strong contractor of open models. Not only are these models terrific entertainers, but their license allows use of their outputs for distillation, possibly pressing forward the cutting-edge for language designs (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
