DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to enhance reasoning capability. DeepSeek-R1 attains outcomes on par with OpenAI's o1 model on numerous benchmarks, consisting of 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 design is fine-tuned using Group Relative Policy Optimization (GRPO), wiki.snooze-hotelsoftware.de a reasoning-oriented variant of RL. The research team likewise performed understanding distillation from DeepSeek-R1 to open-source Qwen and Llama designs and released a number of variations of each; these models outperform larger designs, including GPT-4, on math and coding standards.

[DeepSeek-R1 is] the primary step toward enhancing language design reasoning capabilities using pure reinforcement learning (RL). Our objective is to explore the capacity of LLMs to develop thinking abilities with no supervised data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of jobs, consisting of innovative writing, basic concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates impressive performance on jobs needing long-context understanding, considerably surpassing DeepSeek-V3 on long-context criteria.

To develop the model, DeepSeek began with DeepSeek-V3 as a base. They first tried fine-tuning it just with RL, and without any monitored fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have also launched. This design shows strong reasoning performance, but" effective thinking habits, it faces several issues. For instance, DeepSeek-R1-Zero has problem with difficulties like bad readability and language mixing."

To address this, the group used a brief phase of SFT to avoid the "cold start" problem of RL. They collected several thousand examples of chain-of-thought thinking to use in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then more SFT information using rejection tasting, leading to a dataset of 800k samples. This dataset was used for additional fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek evaluated their model on a range of thinking, mathematics, garagesale.es and disgaeawiki.info coding benchmarks and compared it to other designs, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined 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 general in the arena and # 1 in coding and mathematics. It was also connected for # 1 with o1 in "Hard Prompt with Style Control" category.

Django structure co-creator Simon Willison blogged about his try outs among the DeepSeek distilled Llama designs on his blog site:

Each response starts with a ... pseudo-XML tag containing the chain of thought used to assist produce the response. [Given the timely] "a joke about a pelican and a walrus who run a tea space together" ... It then thought for 20 paragraphs before outputting the joke! ... [T] he joke is horrible. But the process of arriving was such an intriguing insight into how these brand-new designs work.

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

DeepSeek is quickly becoming a strong builder of open models. Not only are these models terrific entertainers, however 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.
