DeepSeek open-sourced DeepSeek-R1, an LLM fine-tuned with support knowing (RL) to enhance thinking 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 experts (MoE) model just recently open-sourced by DeepSeek. This base design is fine-tuned using Group Relative Policy Optimization (GRPO), a reasoning-oriented variation of RL. The research study group also carried out knowledge distillation from DeepSeek-R1 to open-source Qwen and Llama designs and released several variations of each; these designs exceed larger designs, including GPT-4, on mathematics and coding benchmarks.

[DeepSeek-R1 is] the first action toward enhancing language model reasoning abilities utilizing pure reinforcement learning (RL). Our objective is to explore the potential of LLMs to establish reasoning capabilities without any monitored data, focusing on their self-evolution through a pure RL process...DeepSeek-R1 ... excels in a large range of jobs, consisting of creative writing, general question answering, modifying, summarization, and more. Additionally, DeepSeek-R1 demonstrates exceptional efficiency on tasks requiring long-context understanding, substantially surpassing DeepSeek-V3 on long-context benchmarks.

To develop the model, DeepSeek began with DeepSeek-V3 as a base. They first attempted fine-tuning it just with RL, and with no monitored fine-tuning (SFT), producing a model called DeepSeek-R1-Zero, which they have also launched. This model displays strong reasoning performance, however" effective reasoning behaviors, it deals with numerous issues. For instance, DeepSeek-R1-Zero fights with obstacles like poor readability and language mixing."

To resolve this, the team utilized a brief stage of SFT to avoid the "cold start" problem of RL. They collected several thousand examples of chain-of-thought reasoning to use in SFT of DeepSeek-V3 before running RL. After the RL process converged, they then collected more SFT data utilizing rejection sampling, resulting in a dataset of 800k samples. This dataset was used for additional fine-tuning and to produce the distilled designs from Llama and Qwen.

DeepSeek assessed their design on a range of reasoning, mathematics, and coding standards and compared it to other models, including Claude-3.5- Sonnet, GPT-4o, and o1. DeepSeek-R1 surpassed 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 overall 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 structure Simon Willison blogged about his explores one of the DeepSeek distilled Llama models on his blog site:

Each reaction starts with a ... pseudo-XML tag containing the chain of idea used to help create the reaction. [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 awful. But the procedure of arriving was such an intriguing insight into how these brand-new designs work.

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

DeepSeek is rapidly emerging as a strong builder of open designs. Not just are these models fantastic entertainers, but their license allows usage of their outputs for distillation, potentially pressing forward the state of the art for language designs (and multimodal models) of all sizes.

The DeepSeek-R1 designs are available on HuggingFace.
