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 design on numerous criteria, including MATH-500 and SWE-bench.

DeepSeek-R1 is based on DeepSeek-V3, a mix of professionals (MoE) design recently open-sourced by DeepSeek. This base design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research team also performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched numerous versions of each; these designs exceed larger models, consisting of GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the initial step towards enhancing language design reasoning abilities using pure reinforcement knowing (RL). Our goal is to check out the capacity of LLMs to establish thinking abilities with no monitored data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a wide variety of tasks, setiathome.berkeley.edu including creative writing, general question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding efficiency on jobs requiring long-context understanding, significantly outperforming DeepSeek-V3 on long-context benchmarks.

To develop the design, DeepSeek started with DeepSeek-V3 as a base. They initially attempted fine-tuning it just with RL, and with no supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have actually also launched. This model displays strong reasoning efficiency, however" effective thinking habits, it deals with numerous problems. For instance, DeepSeek-R1-Zero fights with obstacles like poor readability and language blending."

To resolve this, the group utilized a brief stage of SFT to prevent the "cold start" problem of RL. They collected numerous 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 utilizing rejection tasting, resulting in a dataset of 800k samples. This dataset was used for further fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek evaluated their model on a range of reasoning, mathematics, and coding benchmarks and compared it to other models, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 surpassed all of them on several 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 general in the arena and # 1 in coding and mathematics. It was also tied for # 1 with o1 in "Hard Prompt with Style Control" category.

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

Each response begins 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 space 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 discussed DeepSeek-R1:

DeepSeek is rapidly emerging as a strong home builder of open designs. Not only are these designs excellent entertainers, but their license permits usage of their outputs for distillation, potentially pressing forward the state of the art for language models (and multimodal designs) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
