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

DeepSeek-R1 is based upon DeepSeek-V3, a mixture of specialists (MoE) model just recently open-sourced by DeepSeek. This base model is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented variant of RL. The research group likewise performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and released several variations of each; these models exceed larger designs, including GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the step toward enhancing language model thinking capabilities using pure support learning (RL). Our objective is to check out the capacity of LLMs to develop thinking capabilities with no monitored information, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... master a wide variety of tasks, including imaginative writing, basic question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates outstanding performance on tasks requiring long-context understanding, substantially exceeding DeepSeek-V3 on long-context benchmarks.

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

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

DeepSeek examined their model on a range of reasoning, mathematics, and coding criteria and compared it to other designs, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined all of them on numerous of the standards, consisting of 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 likewise connected for # 1 with o1 in "Hard Prompt with Style Control" classification.

Django framework co-creator Simon Willison discussed his try outs among the DeepSeek distilled Llama models on his blog:

Each response starts with a ... pseudo-XML tag containing the chain of thought used to help generate the response. [Given the timely] "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 terrible. But the procedure of getting there was such an interesting insight into how these new models work.

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

DeepSeek is quickly emerging as a strong contractor of open designs. Not just are these designs terrific entertainers, however their license permits usage of their outputs for distillation, possibly pushing forward the cutting-edge for language designs (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
