DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement knowing (RL) to improve reasoning ability. DeepSeek-R1 attains results on par with OpenAI's o1 design on several criteria, including MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mix of specialists (MoE) model just recently open-sourced by DeepSeek. This base model is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented variation of RL. The research study team also carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched several versions of each; these models surpass bigger designs, consisting of GPT-4, on math and coding benchmarks.

[DeepSeek-R1 is] the primary step towards enhancing language design thinking abilities using pure support knowing (RL). Our goal is to check out the potential of LLMs to establish thinking capabilities without any monitored data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a large range of tasks, including creative writing, basic question answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates impressive performance on tasks needing long-context understanding, substantially surpassing DeepSeek-V3 on long-context benchmarks.

To develop the design, DeepSeek started 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 also launched. This design exhibits strong reasoning performance, however" powerful reasoning habits, it deals with a number of issues. For example, DeepSeek-R1-Zero fights with challenges like bad readability and language blending."

To address this, the group utilized a short stage of SFT to prevent the "cold start" problem of RL. They gathered numerous thousand examples of chain-of-thought reasoning to use in SFT of DeepSeek-V3 before running RL. After the RL process assembled, wiki.dulovic.tech 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 design on a range of thinking, mathematics, and coding standards and compared it to other models, consisting of 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 revealed that DeepSeek-R1 was ranked # 3 overall in the arena and # 1 in coding and math. It was also connected for # 1 with o1 in "Hard Prompt with Style Control" category.

Django framework co-creator Simon Willison blogged about his explores one of the Llama models on his blog:

Each response starts with a ... pseudo-XML tag containing the chain of thought used to help produce the reaction. [Given the prompt] "a joke about a pelican and a walrus who run a tea space together" ... It then believed for 20 paragraphs before outputting the joke! ... [T] he joke is awful. But the procedure of getting there was such a fascinating insight into how these new models work.

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

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

The DeepSeek-R1 models are available on HuggingFace.
