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

DeepSeek-R1 is based upon DeepSeek-V3, a mix of professionals (MoE) model recently open-sourced by DeepSeek. This base model is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented variation of RL. The research team also performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched a number of variations of each; these designs surpass larger designs, consisting of GPT-4, on math and coding standards.

[DeepSeek-R1 is] the primary step toward enhancing language model thinking abilities using pure reinforcement learning (RL). Our objective is to explore the capacity of LLMs to develop reasoning capabilities without any monitored information, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of tasks, including imaginative writing, general concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding efficiency on tasks needing long-context understanding, substantially outperforming DeepSeek-V3 on long-context benchmarks.

To establish the model, 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 design called DeepSeek-R1-Zero, which they have also launched. This design shows strong reasoning efficiency, however" effective reasoning behaviors, it faces a number of problems. For instance, DeepSeek-R1-Zero battles with challenges like bad readability and language mixing."

To resolve this, the team utilized a brief phase of SFT to prevent the "cold start" issue 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 data utilizing rejection sampling, 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 design on a variety of thinking, math, and coding benchmarks and compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined all of them on several of the benchmarks, consisting of 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 engel-und-waisen.de mathematics. It was likewise connected for # 1 with o1 in "Hard Prompt with Style Control" classification.

Django framework co-creator Simon Willison composed about his explores one of the DeepSeek distilled Llama designs on his blog site:

Each action begins with a ... pseudo-XML tag containing the chain of thought utilized to assist generate the action. [Given the timely] "a joke about a pelican and a walrus who run a tea room together" ... It then believed for 20 paragraphs before outputting the joke! ... [T] he joke is terrible. But the process of getting there was such an intriguing insight into how these new designs work.

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

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

The DeepSeek-R1 models are available on HuggingFace.
