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

DeepSeek-R1 is based on DeepSeek-V3, a mix of professionals (MoE) model recently open-sourced by DeepSeek. This base design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented variant of RL. The research study team also performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched several variations of each; these models outshine bigger designs, including GPT-4, on mathematics and coding benchmarks.

[DeepSeek-R1 is] the initial step towards improving language design reasoning abilities using pure support knowing (RL). Our objective is to explore the potential of LLMs to develop reasoning abilities without any monitored information, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of tasks, consisting of creative writing, general question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates impressive efficiency on tasks needing long-context understanding, considerably exceeding DeepSeek-V3 on long-context benchmarks.

To develop the design, DeepSeek started with DeepSeek-V3 as a base. They first attempted fine-tuning it only with RL, and without any supervised fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have likewise released. This model exhibits strong reasoning efficiency, however" effective thinking behaviors, it faces numerous problems. For instance, DeepSeek-R1-Zero has problem with challenges like poor readability and language blending."

To resolve this, the group used a brief stage of SFT to avoid the "cold start" issue of RL. They collected several thousand examples of chain-of-thought thinking to utilize 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 used for more fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek evaluated their design on a variety of thinking, math, and coding standards and compared it to other models, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined 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 overall 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 blogged about his explores one of the DeepSeek distilled Llama models on his blog:

Each action starts with a ... pseudo-XML tag containing the chain of idea used to assist generate the reaction. [Given the prompt] "a joke about a pelican and a walrus who run a tea room together" ... It then believed for 20 paragraphs before the joke! ... [T] he joke is awful. But the procedure of getting there was such an interesting insight into how these new models work.

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

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

The DeepSeek-R1 models are available on HuggingFace.
