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

DeepSeek-R1 is based upon DeepSeek-V3, a mix of professionals (MoE) model just 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 group 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 exceed bigger designs, including GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the primary step toward enhancing language design thinking capabilities utilizing pure reinforcement learning (RL). Our objective is to explore the potential of LLMs to establish reasoning capabilities with no supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a large range of tasks, consisting of imaginative writing, basic question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates impressive efficiency on tasks requiring long-context understanding, significantly surpassing DeepSeek-V3 on long-context benchmarks.

To develop the model, DeepSeek began 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 model displays strong reasoning efficiency, however" effective thinking habits, it deals with a number of problems. For example, DeepSeek-R1-Zero battles with difficulties like poor readability and language mixing."

To address this, the team used a short phase of SFT to prevent the "cold start" issue 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 procedure converged, they then gathered more SFT data using rejection tasting, resulting in a dataset of 800k samples. This dataset was used for more fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek evaluated their model on a range of reasoning, mathematics, and coding standards and compared it to other models, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined all of them on numerous of the standards, including AIME 2024 and MATH-500.

Within a couple of days of its release, pediascape.science the LMArena announced that DeepSeek-R1 was ranked # 3 overall in the arena and # 1 in coding and math. It was likewise tied for # 1 with o1 in "Hard Prompt with Style Control" category.

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

Each action starts with a ... pseudo-XML tag containing the chain of idea utilized to help generate 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 the joke! ... [T] he joke is terrible. But the process of getting there was such an interesting insight into how these brand-new designs work.

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

DeepSeek is quickly becoming a strong home builder of open models. Not just are these models fantastic entertainers, however their license allows usage 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.
