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

DeepSeek-R1 is based upon DeepSeek-V3, a mix of professionals (MoE) design 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 team likewise performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched numerous versions of each; these designs outshine larger models, consisting of GPT-4, on math and coding benchmarks.

[DeepSeek-R1 is] the initial step toward improving language model reasoning abilities utilizing pure support knowing (RL). Our goal is to explore the capacity of LLMs to establish reasoning abilities with no monitored information, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a vast array of tasks, including innovative writing, general concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional efficiency on tasks needing long-context understanding, significantly outshining DeepSeek-V3 on long-context benchmarks.

To establish the model, DeepSeek began with DeepSeek-V3 as a base. They fine-tuning it only with RL, and without any supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have actually also launched. This design displays strong thinking efficiency, but" powerful thinking habits, it faces several issues. 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 avoid the "cold start" issue of RL. They gathered several thousand examples of chain-of-thought thinking to use in SFT of DeepSeek-V3 before running RL. After the RL process assembled, they then gathered more SFT information using rejection sampling, leading to a dataset of 800k samples. This dataset was utilized for further fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek assessed their design on a range of reasoning, math, systemcheck-wiki.de and coding criteria and compared it to other designs, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed all of them on several of the benchmarks, consisting of AIME 2024 and MATH-500.

Within a few 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 tied for # 1 with o1 in "Hard Prompt with Style Control" category.

Django structure co-creator Simon Willison wrote about his explores among the DeepSeek distilled Llama models on his blog site:

Each response begins with a ... pseudo-XML tag containing the chain of idea utilized to help produce the response. [Given the prompt] "a joke about a pelican and a walrus who run a tea space together" ... It then believed for pediascape.science 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 new designs work.

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

DeepSeek is quickly emerging as a strong contractor of open designs. Not just are these models excellent entertainers, but their license allows usage of their outputs for wiki.eqoarevival.com distillation, potentially pushing forward the cutting-edge for language designs (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
