DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support knowing (RL) to improve reasoning capability. DeepSeek-R1 attains results on par with OpenAI's o1 design on numerous benchmarks, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based on DeepSeek-V3, a mixture 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 team also carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched a number of variations of each; these designs surpass bigger models, including GPT-4, on mathematics and coding benchmarks.

[DeepSeek-R1 is] the primary step towards enhancing language model thinking abilities utilizing pure support knowing (RL). Our goal is to check out the potential of LLMs to develop reasoning abilities with no supervised data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a large range of tasks, including imaginative writing, basic question answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding efficiency on jobs requiring long-context understanding, substantially exceeding DeepSeek-V3 on long-context standards.

To establish the model, DeepSeek started with DeepSeek-V3 as a base. They initially tried 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 design exhibits strong reasoning efficiency, but" powerful thinking habits, it faces numerous issues. For example, DeepSeek-R1-Zero has problem with challenges like poor readability and language mixing."

To resolve this, the group used a brief phase of SFT to prevent the "cold start" issue of RL. They collected numerous thousand examples of chain-of-thought reasoning to utilize in SFT of DeepSeek-V3 before running RL. After the RL procedure assembled, they then collected more SFT data utilizing rejection sampling, leading to a dataset of 800k samples. This dataset was utilized for further fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek evaluated their model on a range of reasoning, math, and coding standards and compared it to other designs, consisting of Claude-3.5- Sonnet, GPT-4o, and wavedream.wiki o1. DeepSeek-R1 outperformed all of them on several of the benchmarks, 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 mathematics. It was likewise connected for # 1 with o1 in "Hard Prompt with Style Control" classification.

Django framework co-creator Simon Willison wrote about his experiments with among the DeepSeek distilled Llama models on his blog:

Each reaction begins with a ... pseudo-XML tag containing the chain of thought used to help 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 getting there was such a fascinating insight into how these brand-new designs work.

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

DeepSeek is quickly emerging as a of open models. Not just are these models great 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 models are available on HuggingFace.
