DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with reinforcement knowing (RL) to enhance thinking 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 on DeepSeek-V3, a mixture of experts (MoE) model recently open-sourced by DeepSeek. This base model is fine-tuned utilizing Group Relative Policy Optimization (GRPO), a reasoning-oriented version of RL. The research group likewise performed knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama models and launched numerous versions of each; these designs outperform bigger designs, consisting of GPT-4, on mathematics and coding criteria.

[DeepSeek-R1 is] the primary step toward improving language model thinking abilities utilizing pure support knowing (RL). Our goal is to check out the potential of LLMs to establish thinking abilities with no monitored information, concentrating on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of tasks, including imaginative writing, basic concern answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional efficiency on tasks requiring long-context understanding, substantially surpassing DeepSeek-V3 on long-context standards.

To establish the design, DeepSeek began with DeepSeek-V3 as a base. They first tried fine-tuning it just with RL, and with no monitored fine-tuning (SFT), producing a design called DeepSeek-R1-Zero, which they have actually likewise launched. This design displays strong reasoning performance, but" effective thinking behaviors, it deals with a number of issues. For example, DeepSeek-R1-Zero struggles with challenges like bad readability and language blending."

To resolve this, the team utilized a short stage of SFT to prevent the "cold start" problem of RL. They collected a number of thousand examples of chain-of-thought reasoning to use in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then gathered more SFT data utilizing rejection tasting, leading to a dataset of 800k samples. This dataset was utilized 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, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 surpassed all of them on numerous of the benchmarks, including AIME 2024 and MATH-500.

Within a few days of its release, wakewiki.de the LMArena announced that DeepSeek-R1 was ranked # 3 overall in the arena and # 1 in coding and mathematics. It was also tied for # 1 with o1 in "Hard Prompt with Style Control" category.

Django framework co-creator Simon Willison blogged about his experiments with one of the DeepSeek distilled Llama designs on his blog site:

Each reaction begins with a ... pseudo-XML tag containing the chain of idea utilized to assist generate the action. [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 awful. But the procedure of arriving was such a fascinating insight into how these designs 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 excellent entertainers, but their license permits use of their outputs for distillation, potentially pressing forward the cutting-edge for language models (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
