DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to improve thinking capability. 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 experts (MoE) design 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 team also carried out understanding distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched a number of variations of each; these designs outshine bigger designs, including GPT-4, on math and coding criteria.

[DeepSeek-R1 is] the very first step toward improving language model thinking capabilities using pure support learning (RL). Our goal is to check out the potential of LLMs to establish thinking capabilities with no monitored data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a vast array of tasks, consisting of creative writing, basic concern answering, modifying, summarization, and more. Additionally, DeepSeek-R1 shows impressive performance on tasks needing long-context understanding, considerably surpassing DeepSeek-V3 on long-context benchmarks.

To establish the design, DeepSeek started with DeepSeek-V3 as a base. They first attempted fine-tuning it only with RL, and with no supervised fine-tuning (SFT), disgaeawiki.info producing a design called DeepSeek-R1-Zero, which they have actually likewise launched. This design exhibits strong reasoning efficiency, but" powerful thinking habits, it faces numerous problems. For example, DeepSeek-R1-Zero has problem with challenges like bad readability and language blending."

To resolve this, the group used a brief stage 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 information utilizing rejection sampling, leading to a dataset of 800k samples. This dataset was utilized for additional fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek assessed their model on a variety 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, the LMArena announced that DeepSeek-R1 was ranked # 3 total in the arena and # 1 in coding and math. It was also connected for # 1 with o1 in "Hard Prompt with Style Control" classification.

Django structure co-creator Simon Willison blogged about his experiments with one of the DeepSeek distilled Llama designs on his blog:

Each action begins with a ... pseudo-XML tag containing the chain of thought used to help produce the action. [Given the timely] "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 dreadful. But the procedure of getting there was such a fascinating insight into how these brand-new designs work.

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

DeepSeek is rapidly becoming a strong builder of open models. Not only are these models great entertainers, but their license allows usage of their outputs for distillation, possibly pushing forward the state of the art for (and multimodal designs) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
