DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support learning (RL) to enhance thinking ability. DeepSeek-R1 attains results on par with OpenAI's o1 design on several standards, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, bytes-the-dust.com a mixture of experts (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 understanding distillation from DeepSeek-R1 to open-source Qwen and Llama models and released several versions of each; these designs exceed larger designs, including GPT-4, on math and coding criteria.

[DeepSeek-R1 is] the primary step toward enhancing language model thinking capabilities using pure support learning (RL). Our goal is to explore the potential of LLMs to establish reasoning capabilities with no supervised data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a large variety of jobs, including innovative writing, general concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional efficiency on jobs requiring long-context understanding, significantly exceeding DeepSeek-V3 on long-context standards.

To develop the model, DeepSeek started with DeepSeek-V3 as a base. They first attempted fine-tuning it only with RL, and with no supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have actually likewise launched. This design displays strong reasoning efficiency, however" powerful thinking behaviors, it deals with several concerns. For example, DeepSeek-R1-Zero battles with challenges like poor readability and language mixing."

To address this, the team utilized a short stage of SFT to prevent the "cold start" problem of RL. They collected several thousand examples of chain-of-thought reasoning to in SFT of DeepSeek-V3 before running RL. After the RL process assembled, they then gathered more SFT information utilizing rejection sampling, leading to 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 range of thinking, mathematics, and coding benchmarks and compared it to other models, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 exceeded all of them on numerous of the criteria, including AIME 2024 and MATH-500.

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

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

Each reaction starts with a ... pseudo-XML tag containing the chain of thought used to help create the response. [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 terrible. But the process of getting there was such a fascinating insight into how these brand-new designs work.

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

DeepSeek is quickly emerging as a strong builder of open models. Not only are these designs great entertainers, but their license permits usage of their outputs for distillation, possibly pushing forward the cutting-edge for language models (and multimodal designs) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
