Introduction to DeepSeek-R1
DeepSeek-R1 represents one of the most ambitious AI models developed by DeepSeek. This model advances the concept of learning solely through reinforcement learning (RL), without the preliminary stage of supervised fine-tuning (SFT). The DeepSeek-R1 system achieves high performance comparable to OpenAI solutions in areas such as mathematics, coding, and general reasoning.
Advantages and Innovations of the DeepSeek-R1 Model
DeepSeek-R1 goes beyond standard training methods by using RL exclusively to stimulate reasoning. This has led to the emergence of such behavioral traits as self-verification, reflection, and the creation of long chains of thought. It is worth noting that DeepSeek-R1 is the first to demonstrate how reasoning capabilities can be developed purely through RL, without SFT. However, despite the outstanding results, the model has limitations: issues with repetition, readability, and language mixing.

DeepSeek-R1's Advantages Over Competitors
DeepSeek-R1 was enhanced compared to its predecessor, DeepSeek-R1-Zero. One of the key improvements was the addition of a cold-start phase before RL training, which significantly boosted the model’s reasoning abilities and resolved several limitations. The results showed that DeepSeek-R1 outperforms OpenAI on several metrics in tasks such as solving mathematical problems, coding, and general reasoning.
Note: DeepSeek-R1 opens new possibilities for AI applications, demonstrating comparable or even superior performance in several categories.
Challenges and Solutions of DeepSeek-R1
During the development process, DeepSeek encountered a number of limitations, including endless repetition and readability issues. However, the company developed an improved version of the model—DeepSeek-R1—that addressed these problems and significantly improved overall efficiency for real-world applications. Introducing pre-training in the form of a cold-start phase proved to be key to improving reasoning quality.
The Importance of Distillation for Performance Enhancement
DeepSeek actively employs the technique of distillation, which allows reasoning capabilities to be transferred from larger models to smaller, more efficient versions. This significantly improved results even for smaller models. For example, DeepSeek-R1-Distill-Qwen-32B delivered outstanding results, outperforming OpenAI’s o1-mini in several key benchmarks.
Note: Distillation enables the creation of faster and more compact versions of models, opening up new possibilities for their use in various applications.
The Importance of Open-Sourcing and Licensing
DeepSeek decided to open-source both DeepSeek-R1 and its predecessor DeepSeek-R1-Zero, allowing researchers and developers to take advantage of the model’s capabilities. The model is licensed under the MIT License, allowing commercial use and modifications for the creation of new solutions. However, users of some distilled models must comply with the licensing terms of the original base models.
