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

DeepSeek-R1 is based upon DeepSeek-V3, a mix of specialists (MoE) design recently open-sourced by DeepSeek. This base design is fine-tuned using Group Relative Policy Optimization (GRPO), gratisafhalen.be a reasoning-oriented version of RL. The research group also carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched numerous variations of each; these designs surpass bigger designs, consisting of GPT-4, on mathematics and coding standards.

[DeepSeek-R1 is] the initial step towards design reasoning abilities using pure reinforcement knowing (RL). Our objective is to explore the capacity of LLMs to develop thinking capabilities without any supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of tasks, consisting of imaginative writing, general question answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates impressive performance on tasks requiring long-context understanding, considerably surpassing DeepSeek-V3 on long-context criteria.

To establish the design, DeepSeek began with DeepSeek-V3 as a base. They initially tried 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 released. This design shows strong thinking performance, but" effective reasoning habits, it faces numerous issues. For instance, DeepSeek-R1-Zero struggles with challenges like poor readability and language mixing."

To address this, the team used a brief phase of SFT to prevent the "cold start" problem of RL. They gathered numerous thousand examples of chain-of-thought thinking to use in SFT of DeepSeek-V3 before running RL. After the RL procedure assembled, they then collected more SFT information 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, math, 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 benchmarks, 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 math. It was also tied for # 1 with o1 in "Hard Prompt with Style Control" category.

Django framework co-creator Simon Willison blogged about his try outs among the DeepSeek distilled Llama designs on his blog:

Each action begins with a ... pseudo-XML tag containing the chain of thought utilized to assist generate the reaction. [Given the prompt] "a joke about a pelican and a walrus who run a tea room together" ... It then thought for 20 paragraphs before outputting the joke! ... [T] he joke is dreadful. But the procedure of arriving was such an intriguing insight into how these brand-new designs work.

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

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

The DeepSeek-R1 models are available on HuggingFace.
