DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement knowing (RL) to improve reasoning 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 mix of professionals (MoE) model recently open-sourced by DeepSeek. This base design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented variant of RL. The research team also performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched several versions of each; these models surpass bigger designs, consisting of GPT-4, on math and coding criteria.

[DeepSeek-R1 is] the initial step toward improving language model reasoning abilities utilizing pure reinforcement learning (RL). Our goal is to check out the potential of LLMs to establish reasoning capabilities with no data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a wide variety of jobs, consisting of creative writing, basic concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding performance on tasks needing long-context understanding, substantially outperforming DeepSeek-V3 on long-context criteria.

To develop the model, DeepSeek started with DeepSeek-V3 as a base. They first tried fine-tuning it only with RL, and without any monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have actually also launched. This design shows strong reasoning performance, however" effective thinking behaviors, it faces several concerns. For circumstances, DeepSeek-R1-Zero struggles with difficulties like poor 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 reasoning to utilize in SFT of DeepSeek-V3 before running RL. After the RL process assembled, they then gathered more SFT information utilizing rejection tasting, leading to a dataset of 800k samples. This dataset was utilized for more 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 designs, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed all of them on numerous of the benchmarks, consisting of AIME 2024 and MATH-500.

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

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

Each response begins with a ... pseudo-XML tag containing the chain of thought utilized to assist create 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 awful. But the process of arriving was such a fascinating insight into how these brand-new models work.

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

DeepSeek is quickly emerging as a strong contractor of open designs. Not just are these designs terrific entertainers, but their license allows use of their outputs for distillation, possibly pushing forward the state of the art for language designs (and multimodal designs) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
