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

DeepSeek-R1 is based upon DeepSeek-V3, a mix of specialists (MoE) model just 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 group likewise performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and launched a number of variations of each; these models surpass bigger designs, consisting of GPT-4, on math and coding benchmarks.

[DeepSeek-R1 is] the initial step towards enhancing language design thinking abilities using pure reinforcement knowing (RL). Our goal is to explore the potential of LLMs to establish reasoning capabilities without any monitored data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a broad range of jobs, consisting of imaginative writing, basic concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional efficiency on jobs needing long-context understanding, considerably outshining DeepSeek-V3 on long-context standards.

To establish the model, DeepSeek began with DeepSeek-V3 as a base. They first attempted fine-tuning it just with RL, and without any monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have likewise launched. This model displays strong reasoning performance, however" effective reasoning habits, it deals with several problems. For example, DeepSeek-R1-Zero has problem with challenges like poor readability and language mixing."

To address this, the group utilized a short stage of SFT to avoid the "cold start" issue of RL. They collected several thousand of chain-of-thought thinking to utilize in SFT of DeepSeek-V3 before running RL. After the RL procedure converged, they then collected more SFT data utilizing rejection tasting, resulting in a dataset of 800k samples. This dataset was utilized for further fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek evaluated their design on a variety of reasoning, mathematics, and coding standards and compared it to other designs, engel-und-waisen.de including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outshined all of them on several of the criteria, consisting of 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 connected for # 1 with o1 in "Hard Prompt with Style Control" classification.

Django structure co-creator Simon Willison composed about his explores among the DeepSeek distilled Llama designs on his blog:

Each response begins with a ... pseudo-XML tag containing the chain of thought used to help generate the action. [Given the prompt] "a joke about a pelican and a walrus who run a tea space together" ... It then believed for 20 paragraphs before outputting the joke! ... [T] he joke is terrible. But the procedure of getting there was such a fascinating 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 designs terrific entertainers, however their license allows usage of their outputs for distillation, possibly pressing forward the cutting-edge for language models (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
