DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to capability. DeepSeek-R1 attains outcomes on par with OpenAI's o1 model on several standards, consisting of 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 design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research study team also performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and released numerous variations of each; these designs outperform larger designs, consisting of GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the primary step toward enhancing language design reasoning capabilities utilizing pure reinforcement knowing (RL). Our objective is to explore the potential of LLMs to develop thinking capabilities with no supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a broad variety of tasks, consisting of innovative writing, basic question answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional efficiency on tasks requiring long-context understanding, considerably surpassing DeepSeek-V3 on long-context benchmarks.

To establish the design, DeepSeek started with DeepSeek-V3 as a base. They initially attempted fine-tuning it just with RL, and without any supervised fine-tuning (SFT), hb9lc.org producing a model called DeepSeek-R1-Zero, it-viking.ch which they have also released. This model shows strong thinking performance, but" powerful reasoning behaviors, it faces several problems. For circumstances, DeepSeek-R1-Zero struggles with difficulties like bad readability and language mixing."

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

DeepSeek assessed their design on a variety of thinking, math, and coding criteria and compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed 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 total in the arena and # 1 in coding and mathematics. It was likewise connected for # 1 with o1 in "Hard Prompt with Style Control" classification.

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

Each response 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 believed for 20 paragraphs before outputting the joke! ... [T] he joke is awful. But the process of getting there was such an interesting insight into how these brand-new models work.

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

DeepSeek is rapidly becoming a strong contractor of open designs. Not just are these models excellent entertainers, but their license allows use of their outputs for distillation, potentially pushing forward the cutting-edge for language designs (and multimodal models) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
