DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement learning (RL) to improve thinking capability. DeepSeek-R1 attains results 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 mix of specialists (MoE) design just recently open-sourced by DeepSeek. This base design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), pipewiki.org a reasoning-oriented version of RL. The research study group also carried out 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 standards.

[DeepSeek-R1 is] the primary step toward enhancing language design reasoning capabilities using pure reinforcement knowing (RL). Our goal is to check out the capacity of LLMs to establish reasoning capabilities without any monitored information, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a large range of jobs, including creative writing, general concern answering, modifying, summarization, and more. Additionally, DeepSeek-R1 shows exceptional performance on tasks needing long-context understanding, considerably exceeding DeepSeek-V3 on long-context criteria.

To establish the design, DeepSeek started with DeepSeek-V3 as a base. They first tried fine-tuning it only with RL, and without any monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have likewise launched. This model shows strong thinking efficiency, however" powerful reasoning habits, it deals with several concerns. For example, DeepSeek-R1-Zero deals with obstacles like bad readability and language mixing."

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

DeepSeek examined their design on a range of reasoning, math, systemcheck-wiki.de and coding standards and compared it to other designs, consisting of 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 couple of days of its release, the LMArena announced that DeepSeek-R1 was ranked # 3 general 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 structure co-creator Simon Willison blogged about his try outs among the DeepSeek distilled Llama designs on his blog:

Each action starts with a ... pseudo-XML tag containing the chain of thought used to assist produce the action. [Given the prompt] "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 horrible. But the process of arriving was such an intriguing 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 designs. Not just are these models great entertainers, setiathome.berkeley.edu but their license permits use of their outputs for distillation, possibly pushing forward the state of the art for language models (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
