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

DeepSeek-R1 is based upon DeepSeek-V3, a mix of experts (MoE) design recently open-sourced by DeepSeek. This base design is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research study group also performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and released several variations of each; these designs exceed larger models, consisting of GPT-4, on math and coding standards.

[DeepSeek-R1 is] the very first action toward enhancing language model thinking capabilities using pure support knowing (RL). Our objective is to check out the potential of LLMs to develop reasoning capabilities without any monitored information, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of jobs, including innovative writing, basic question answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional performance on jobs needing long-context understanding, considerably exceeding DeepSeek-V3 on long-context benchmarks.

To develop the design, DeepSeek started with DeepSeek-V3 as a base. They first tried fine-tuning it just with RL, and with no monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have likewise released. This model shows strong thinking performance, but" powerful reasoning behaviors, it deals with several issues. For example, DeepSeek-R1-Zero deals with challenges like bad readability and language blending."

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

DeepSeek evaluated their design on a range of reasoning, math, and coding benchmarks and compared it to other designs, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 exceeded all of them on numerous 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 general in the arena and # 1 in coding and math. It was also connected for # 1 with o1 in "Hard Prompt with Style Control" classification.

Django framework co-creator Simon Willison composed about his try outs one of the DeepSeek distilled Llama models on his blog:

Each reaction begins with a ... pseudo-XML tag containing the chain of thought used to help produce the action. [Given the timely] "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 awful. But the process of getting there was such a fascinating insight into how these new models work.

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

DeepSeek is rapidly becoming a strong builder of open designs. Not just are these models fantastic entertainers, however their license allows use of their outputs for gratisafhalen.be distillation, potentially pushing forward the state of the art for language models (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
