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

DeepSeek-R1 is based on DeepSeek-V3, a mix of (MoE) model 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 launched several variations of each; these models exceed bigger models, consisting of GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the initial step toward improving language model reasoning capabilities utilizing pure reinforcement learning (RL). Our goal is to explore the capacity of LLMs to develop reasoning capabilities with no supervised data, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... master a vast array of tasks, including creative writing, general concern answering, editing, summarization, and more. Additionally, DeepSeek-R1 shows outstanding performance on tasks requiring long-context understanding, substantially outperforming DeepSeek-V3 on long-context benchmarks.

To develop the design, DeepSeek began with DeepSeek-V3 as a base. They first tried fine-tuning it only with RL, and without any supervised fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have also launched. This model exhibits strong thinking efficiency, but" powerful thinking behaviors, it deals with a number of concerns. For instance, DeepSeek-R1-Zero deals with difficulties like bad readability and language mixing."

To resolve this, the group utilized a brief phase of SFT to prevent the "cold start" issue of RL. They gathered several thousand examples of chain-of-thought reasoning to utilize in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then gathered more SFT information utilizing rejection sampling, leading to a dataset of 800k samples. This dataset was used for additional fine-tuning and to produce the distilled models from Llama and Qwen.

DeepSeek evaluated their design on a variety of reasoning, mathematics, and coding criteria and compared it to other designs, consisting of Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 outperformed all of them on several of the criteria, consisting of AIME 2024 and MATH-500.

Within a few 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 tied for # 1 with o1 in "Hard Prompt with Style Control" category.

Django structure co-creator Simon Willison composed about his experiments with among the DeepSeek distilled Llama models on his blog site:

Each action starts with a ... pseudo-XML tag containing the chain of idea utilized to help create the response. [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 terrible. But the procedure of arriving was such an interesting 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 only are these designs excellent entertainers, but their license allows use of their outputs for distillation, potentially pressing forward the state of the art for yewiki.org language models (and wiki.eqoarevival.com multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
