DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support knowing (RL) to enhance thinking capability. DeepSeek-R1 attains outcomes on par with OpenAI's o1 design on a number of benchmarks, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mixture of experts (MoE) model recently open-sourced by DeepSeek. This base design is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research team likewise performed understanding distillation from DeepSeek-R1 to open-source Qwen and Llama models and released a number of variations of each; these models surpass bigger models, consisting of GPT-4, pipewiki.org on math and coding standards.

[DeepSeek-R1 is] the primary step towards enhancing language model reasoning abilities using pure reinforcement learning (RL). Our objective is to explore the capacity of LLMs to establish thinking capabilities without any supervised information, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a wide variety of jobs, including innovative writing, general question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding performance on jobs requiring long-context understanding, pipewiki.org significantly outperforming DeepSeek-V3 on long-context benchmarks.

To develop the design, DeepSeek started with DeepSeek-V3 as a base. They first tried fine-tuning it only with RL, and with no supervised fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have also launched. This model shows strong reasoning performance, however" powerful thinking behaviors, it deals with several problems. For example, DeepSeek-R1-Zero fights with challenges like bad readability and language mixing."

To address this, the group used a brief stage of SFT to prevent the "cold start" issue of RL. They collected numerous thousand examples of chain-of-thought thinking to utilize in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then collected more SFT information utilizing rejection tasting, it-viking.ch resulting in a dataset of 800k samples. This dataset was utilized for more fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek examined their design on a variety of reasoning, mathematics, and coding criteria and compared it to other models, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 exceeded all of them on numerous of the criteria, 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 mathematics. It was also tied for # 1 with o1 in "Hard Prompt with Style Control" category.

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

Each action begins with a ... pseudo-XML tag containing the chain of idea utilized to help produce the reaction. [Given the prompt] "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 awful. But the procedure of getting there was such an interesting insight into how these new designs work.

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

DeepSeek is quickly becoming a strong builder of open models. Not just are these models fantastic entertainers, but their license permits usage of their outputs for distillation, possibly pressing forward the cutting-edge for language models (and yewiki.org multimodal models) of all sizes.

The DeepSeek-R1 models are available on HuggingFace.
