DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to improve thinking ability. DeepSeek-R1 attains outcomes on par with OpenAI's o1 model on several benchmarks, consisting of MATH-500 and SWE-bench.

DeepSeek-R1 is based upon DeepSeek-V3, a mixture of experts (MoE) design recently open-sourced by DeepSeek. This base design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented variant of RL. The research study team also performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched several versions of each; these designs surpass larger models, including GPT-4, on mathematics and coding benchmarks.

[DeepSeek-R1 is] the very first step towards improving language model reasoning abilities utilizing pure support learning (RL). Our objective is to explore the potential of LLMs to develop reasoning abilities with no supervised information, engel-und-waisen.de concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a wide variety of tasks, consisting of creative writing, general question answering, editing, summarization, and more. Additionally, DeepSeek-R1 shows exceptional performance on tasks needing long-context understanding, substantially exceeding DeepSeek-V3 on long-context benchmarks.

To develop the design, DeepSeek started with DeepSeek-V3 as a base. They first attempted fine-tuning it just with RL, and with no monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have also launched. This model displays strong thinking performance, but" effective thinking behaviors, it faces numerous issues. For circumstances, DeepSeek-R1-Zero fights with obstacles like bad readability and language blending."

To resolve this, the group utilized a brief phase of SFT to prevent the "cold start" issue of RL. They gathered numerous thousand examples of chain-of-thought reasoning to use in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then collected more SFT information using rejection sampling, leading to a dataset of 800k samples. This dataset was used for additional fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek examined their design on a variety of reasoning, mathematics, and coding benchmarks and compared it to other models, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 exceeded all of them on several of the criteria, mediawiki.hcah.in including AIME 2024 and MATH-500.

Within a couple of 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 also tied for larsaluarna.se # 1 with o1 in "Hard Prompt with Style Control" category.

Django framework co-creator Simon Willison composed 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 help produce the action. [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 arriving was such an intriguing insight into how these new models work.

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

DeepSeek is quickly becoming a strong home builder of open models. Not only are these models terrific entertainers, however their license permits use 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.
