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

DeepSeek-R1 is based upon DeepSeek-V3, a mix of specialists (MoE) model recently open-sourced by DeepSeek. This base design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research team also performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched a number of versions of each; these models surpass larger models, consisting of GPT-4, on math and coding benchmarks.

[DeepSeek-R1 is] the first action toward improving language design thinking abilities utilizing pure reinforcement knowing (RL). Our goal is to check out the capacity of LLMs to develop reasoning capabilities without any monitored data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a vast array of jobs, including creative writing, general question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding performance on jobs needing long-context understanding, substantially outperforming DeepSeek-V3 on long-context benchmarks.

To develop the model, DeepSeek began 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 actually also released. This design displays strong thinking efficiency, however" powerful reasoning behaviors, it faces a number of concerns. For instance, DeepSeek-R1-Zero has problem with difficulties like poor readability and language mixing."

To address this, the team used a short 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 data using tasting, leading to a dataset of 800k samples. This dataset was used for further fine-tuning and surgiteams.com to produce the distilled designs from Llama and Qwen.

DeepSeek assessed their model on a variety of thinking, math, 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 numerous of the standards, 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 also connected for # 1 with o1 in "Hard Prompt with Style Control" category.

Django framework co-creator Simon Willison wrote about his experiments with one of the DeepSeek distilled Llama models on his blog:

Each action begins with a ... pseudo-XML tag containing the chain of thought used to assist produce the action. [Given the prompt] "a joke about a pelican and a walrus who run a tea space together" ... It then believed for 20 paragraphs before outputting the joke! ... [T] he joke is dreadful. But the procedure of getting there was such an intriguing insight into how these new models work.

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

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

The DeepSeek-R1 models are available on HuggingFace.
