DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to enhance thinking capability. DeepSeek-R1 attains results on par with OpenAI's o1 model on a number of standards, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mixture of experts (MoE) model just recently open-sourced by DeepSeek. This base model 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 designs outperform larger models, including GPT-4, on math and coding standards.

[DeepSeek-R1 is] the initial step towards enhancing language model reasoning capabilities using pure support knowing (RL). Our goal is to explore the capacity of LLMs to establish reasoning abilities with no monitored information, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a wide variety of tasks, consisting of creative writing, general question answering, editing, summarization, and more. Additionally, DeepSeek-R1 shows exceptional efficiency on tasks needing long-context understanding, substantially outshining DeepSeek-V3 on long-context benchmarks.

To develop 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), forum.batman.gainedge.org producing a design called DeepSeek-R1-Zero, which they have also launched. This model shows strong reasoning efficiency, however" effective reasoning behaviors, it faces numerous problems. For circumstances, DeepSeek-R1-Zero has problem with obstacles like bad readability and language blending."

To resolve this, the group used a short stage of SFT to prevent the "cold start" issue of RL. They gathered numerous thousand examples of chain-of-thought thinking to utilize in SFT of DeepSeek-V3 before running RL. After the RL process assembled, they then gathered more SFT information utilizing rejection tasting, resulting in a dataset of 800k samples. This dataset was used for additional fine-tuning and to produce the distilled models from Llama and setiathome.berkeley.edu Qwen.

DeepSeek assessed their model on a range of reasoning, math, pipewiki.org and coding criteria and compared it to other designs, demo.qkseo.in including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 exceeded all of them on several of the benchmarks, including 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 math. It was likewise tied for # 1 with o1 in "Hard Prompt with Style Control" classification.

Django structure co-creator Simon Willison wrote about his explores one of the DeepSeek distilled Llama models on his blog:

Each action starts with a ... pseudo-XML tag containing the chain of thought utilized to assist create the response. [Given the prompt] "a joke about a pelican and a walrus who run a tea space together" ... It then believed for larsaluarna.se 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 wrote about DeepSeek-R1:

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

The DeepSeek-R1 models are available on HuggingFace.
