DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement knowing (RL) to improve reasoning capability. DeepSeek-R1 attains results on par with OpenAI's o1 model on several criteria, including MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mix of experts (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 group likewise carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and released several versions of each; these models surpass larger models, including GPT-4, on mathematics and coding benchmarks.

[DeepSeek-R1 is] the initial step toward enhancing language model thinking capabilities utilizing pure support learning (RL). Our objective is to explore the capacity of LLMs to develop thinking abilities without any data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a wide variety of tasks, consisting of imaginative writing, basic concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional efficiency on jobs needing long-context understanding, significantly surpassing DeepSeek-V3 on long-context standards.

To establish the design, DeepSeek started with DeepSeek-V3 as a base. They first tried fine-tuning it only with RL, and with no monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have also released. This design displays strong thinking performance, however" powerful thinking behaviors, it faces a number of concerns. For instance, DeepSeek-R1-Zero battles with obstacles like bad readability and language mixing."

To address this, the team used a short phase of SFT to avoid the "cold start" issue of RL. They gathered a number of thousand examples of chain-of-thought reasoning to utilize in SFT of DeepSeek-V3 before running RL. After the RL procedure converged, they then collected more SFT information using rejection tasting, leading to a dataset of 800k samples. This dataset was utilized for further fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek assessed their design on a range of reasoning, mathematics, and coding standards and compared it to other designs, 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 couple of days of its release, the LMArena announced that DeepSeek-R1 was ranked # 3 general in the arena and bytes-the-dust.com # 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 blogged about his experiments with one of the DeepSeek distilled Llama models on his blog:

Each action begins with a ... pseudo-XML tag containing the chain of idea utilized to assist generate the action. [Given the prompt] "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 awful. But the process of arriving was such a fascinating insight into how these brand-new models work.

Andrew Ng's newsletter The Batch discussed DeepSeek-R1:

DeepSeek is rapidly emerging as a strong home builder of open designs. Not only are these models great entertainers, but their license permits use of their outputs for distillation, possibly pressing forward the state of the art for language designs (and multimodal models) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
