DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to enhance thinking 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 on DeepSeek-V3, a mix of specialists (MoE) design 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 likewise performed understanding distillation from DeepSeek-R1 to open-source Qwen and Llama models and released several variations of each; these models outshine larger models, including GPT-4, on math and coding standards.

[DeepSeek-R1 is] the primary step toward improving language model thinking abilities using pure reinforcement learning (RL). Our goal is to explore the capacity of LLMs to develop reasoning capabilities with no supervised data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a vast array of jobs, consisting of creative writing, general concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional performance on jobs needing long-context understanding, substantially exceeding DeepSeek-V3 on long-context standards.

To establish the model, DeepSeek started with DeepSeek-V3 as a base. They initially attempted fine-tuning it only with RL, 89u89.com and with no supervised fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have actually also launched. This model exhibits strong reasoning performance, but" effective thinking behaviors, it faces a number of problems. For example, DeepSeek-R1-Zero fights with difficulties like poor readability and language blending."

To resolve this, the group used a short phase of SFT to avoid the "cold start" issue of RL. They gathered numerous thousand examples of chain-of-thought thinking to use in SFT of DeepSeek-V3 before running RL. After the RL procedure assembled, they then gathered more SFT data utilizing rejection tasting, 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 examined their design on a variety of thinking, math, and coding criteria and compared it to other designs, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed all of them on numerous of the standards, including AIME 2024 and MATH-500.

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

Django framework co-creator Simon Willison discussed his try outs one of the DeepSeek distilled Llama models on his blog:

Each reaction starts with a ... pseudo-XML tag containing the chain of thought utilized to help produce the reaction. [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 terrible. But the procedure of arriving was such an intriguing insight into how these brand-new models work.

newsletter The Batch discussed DeepSeek-R1:

DeepSeek is rapidly emerging as a strong home builder of open models. Not just are these designs fantastic entertainers, however their license permits use of their outputs for distillation, potentially pushing forward the state of the art for language designs (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
