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

DeepSeek-R1 is based on DeepSeek-V3, a mixture of specialists (MoE) model just 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 study team likewise performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and released a number of versions of each; these designs exceed bigger models, consisting of GPT-4, on mathematics and coding standards.

[DeepSeek-R1 is] the primary step toward enhancing language model thinking capabilities utilizing pure reinforcement learning (RL). Our goal is to check out the potential of LLMs to establish thinking capabilities with no supervised data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a large range of jobs, including creative writing, general question answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding performance on jobs needing long-context understanding, considerably outshining DeepSeek-V3 on long-context benchmarks.

To establish the model, DeepSeek began with DeepSeek-V3 as a base. They initially attempted fine-tuning it only with RL, and with no monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have likewise launched. This model exhibits strong performance, but" powerful thinking behaviors, it faces numerous problems. For instance, DeepSeek-R1-Zero deals with challenges like bad readability and language mixing."

To resolve this, the team utilized a short phase of SFT to avoid the "cold start" problem of RL. They gathered several thousand examples of chain-of-thought reasoning to use in SFT of DeepSeek-V3 before running RL. After the RL procedure converged, they then gathered more SFT data using rejection tasting, resulting in a dataset of 800k samples. This dataset was used for more fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek assessed their design on a variety of reasoning, math, and coding criteria and compared it to other models, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed all of them on numerous of the standards, consisting of AIME 2024 and MATH-500.

Within a few days of its release, the LMArena revealed that DeepSeek-R1 was ranked # 3 general 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 blogged about his experiments with among the DeepSeek distilled Llama designs on his blog site:

Each action starts with a ... pseudo-XML tag containing the chain of idea used to assist create the reaction. [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 terrible. But the process of getting there was such an interesting insight into how these brand-new designs work.

Andrew Ng's newsletter The Batch wrote about DeepSeek-R1:

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

The DeepSeek-R1 designs are available on HuggingFace.
