DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to enhance reasoning ability. DeepSeek-R1 attains results on par with OpenAI's o1 model on numerous criteria, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based on DeepSeek-V3, a mix of specialists (MoE) design just 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 understanding distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched several versions of each; these models outperform larger designs, consisting of GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the first action towards enhancing language model thinking capabilities utilizing pure support knowing (RL). Our objective is to explore the capacity of LLMs to develop thinking abilities without any supervised data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a vast array of jobs, consisting of innovative writing, basic question answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates on tasks needing long-context understanding, considerably outperforming DeepSeek-V3 on long-context criteria.

To establish the model, DeepSeek began with DeepSeek-V3 as a base. They first attempted fine-tuning it just with RL, wiki.dulovic.tech and with no monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have likewise launched. This model exhibits strong thinking performance, however" powerful thinking behaviors, it faces a number of concerns. For example, DeepSeek-R1-Zero has problem with challenges like poor readability and language mixing."

To address this, the group utilized a brief stage of SFT to avoid the "cold start" problem of RL. They gathered 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 collected more SFT data using rejection tasting, leading to a dataset of 800k samples. This dataset was utilized for further fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek assessed their design on a range of thinking, math, and coding criteria and compared it to other models, consisting of 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" category.

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

Each reaction begins with a ... pseudo-XML tag containing the chain of idea used to assist create the action. [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 awful. But the process of arriving was such an intriguing insight into how these brand-new designs work.

Andrew Ng's newsletter The Batch discussed DeepSeek-R1:

DeepSeek is quickly emerging as a strong home builder of open designs. Not just are these models great entertainers, but their license allows use of their outputs for distillation, potentially pushing forward the state of the art for language models (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
