DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support learning (RL) to enhance reasoning ability. DeepSeek-R1 attains outcomes on par with OpenAI's o1 model on several criteria, including MATH-500 and SWE-bench.

DeepSeek-R1 is based on DeepSeek-V3, a mix of specialists (MoE) model recently open-sourced by DeepSeek. This base model is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research study team also carried out understanding distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched several versions of each; these designs outperform bigger models, consisting of GPT-4, on math and coding criteria.

[DeepSeek-R1 is] the very first step towards improving language design thinking capabilities using pure support learning (RL). Our goal is to explore the capacity of LLMs to develop thinking capabilities with no supervised information, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a vast array of jobs, setiathome.berkeley.edu including innovative writing, general question answering, editing, summarization, and more. Additionally, DeepSeek-R1 shows outstanding efficiency on tasks needing long-context understanding, significantly outperforming DeepSeek-V3 on long-context standards.

To establish the design, DeepSeek started with DeepSeek-V3 as a base. They first tried fine-tuning it just with RL, and without any supervised fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have likewise launched. This design exhibits strong reasoning performance, but" powerful reasoning habits, it faces a number of concerns. For circumstances, DeepSeek-R1-Zero has problem with challenges like bad readability and language blending."

To resolve this, the team used a brief phase of SFT to prevent the "cold start" problem of RL. They gathered several thousand examples of chain-of-thought thinking to utilize in SFT of DeepSeek-V3 before running RL. After the RL procedure assembled, they then gathered more SFT information utilizing rejection sampling, resulting in a dataset of 800k samples. This dataset was used for more fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek evaluated their model on a variety of reasoning, mathematics, and coding benchmarks and compared it to other models, Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 exceeded all of them on numerous of the standards, 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" category.

Django structure co-creator Simon Willison composed about his explores one of the DeepSeek distilled Llama designs on his blog site:

Each reaction begins with a ... pseudo-XML tag containing the chain of thought used to help produce the response. [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 an intriguing insight into how these brand-new models work.

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

DeepSeek is quickly becoming a strong builder of open designs. Not only are these designs excellent entertainers, but their license permits use of their outputs for distillation, potentially pushing forward the state of the art for language models (and multimodal models) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
