DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support learning (RL) to improve thinking ability. DeepSeek-R1 attains outcomes 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 mixture 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 group also carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched several variations of each; these models surpass bigger models, including GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the primary step towards enhancing language model thinking abilities utilizing pure support learning (RL). Our objective is to explore the potential of LLMs to establish thinking capabilities with no supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a large range of tasks, consisting of innovative writing, basic question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding efficiency on jobs requiring long-context understanding, considerably outshining DeepSeek-V3 on long-context standards.

To establish the design, DeepSeek started with DeepSeek-V3 as a base. They first tried fine-tuning it only with RL, and with no monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, it-viking.ch which they have also launched. This model exhibits strong reasoning performance, however" effective thinking habits, it deals with several issues. For instance, DeepSeek-R1-Zero has problem with challenges like poor readability and language blending."

To address this, the group used a short stage of SFT to avoid the "cold start" problem of RL. They gathered a number of thousand examples of chain-of-thought thinking to use in SFT of DeepSeek-V3 before running RL. After the RL process assembled, they then collected more SFT data using rejection tasting, leading to a dataset of 800k samples. This dataset was used for additional fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek examined their model on a range of reasoning, math, and coding benchmarks and compared it to other designs, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed all of them on numerous of the criteria, including AIME 2024 and MATH-500.

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

Django structure 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 help produce the response. [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 horrible. But the process of arriving was such an interesting insight into how these new designs work.

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

DeepSeek is quickly becoming a strong home builder of open designs. Not only are these designs fantastic entertainers, but their license allows use of their outputs for distillation, possibly pushing forward the state of the art for language designs (and models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
