DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement knowing (RL) to improve thinking capability. DeepSeek-R1 attains results on par with OpenAI's o1 design on numerous standards, consisting of 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 design is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented variant of RL. The research study team also carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and released a number of versions of each; these models exceed bigger models, consisting of GPT-4, on math and coding standards.

[DeepSeek-R1 is] the primary step towards improving language design reasoning capabilities using pure reinforcement learning (RL). Our objective is to explore the potential of LLMs to develop reasoning capabilities with no supervised information, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of jobs, including innovative writing, general question answering, editing, summarization, and more. Additionally, DeepSeek-R1 shows outstanding performance on jobs requiring long-context understanding, significantly outperforming DeepSeek-V3 on long-context benchmarks.

To establish the model, DeepSeek began with DeepSeek-V3 as a base. They initially attempted fine-tuning it only with RL, and without any supervised fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have also launched. This model shows strong thinking efficiency, but" powerful reasoning behaviors, it faces a number of issues. For circumstances, DeepSeek-R1-Zero battles with challenges like poor readability and language blending."

To address this, the group utilized a short phase of SFT to avoid the "cold start" issue of RL. They gathered a number of thousand examples of chain-of-thought thinking to utilize in SFT of DeepSeek-V3 before running RL. After the RL procedure converged, they then gathered more SFT data utilizing rejection sampling, resulting in a dataset of 800k samples. This dataset was utilized for additional fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek examined their model on a range of thinking, mathematics, and coding criteria 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 standards, including AIME 2024 and MATH-500.

Within a few days of its release, the LMArena revealed that DeepSeek-R1 was ranked # 3 total 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 structure co-creator Simon Willison discussed his explores one of the DeepSeek distilled Llama models on his blog site:

Each response begins with a ... pseudo-XML tag containing the chain of idea used to help create the . [Given the prompt] "a joke about a pelican and a walrus who run a tea space together" ... It then thought for 20 paragraphs before outputting the joke! ... [T] he joke is horrible. But the process of getting there was such an interesting insight into how these new models work.

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

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

The DeepSeek-R1 designs are available on HuggingFace.
