The explosive growth of artificial intelligence has led to the development of diverse large language models (LLMs) and multimodal models, dividing the field into open-source and proprietary models. This dichotomy is exemplified by DeepSeek-R1 and OpenAI’s o1, respectively. DeepSeek-R1, an open-source model developed by the Chinese research company DeepSeek-AI, presents a significant challenge to proprietary models like OpenAI’s o1. This emergence has sparked discussions on cost efficiency, open-source innovation, and global leadership in AI technology. This analysis delves into DeepSeek-R1’s development, capabilities, and implications while comparing them with OpenAI’s o1 system.
The Development Process of DeepSeek-R1
DeepSeek-R1 adopts a unique multi-stage training process for advanced reasoning capabilities, building upon its predecessor, DeepSeek-R1-Zero. Unlike its successor, DeepSeek-R1-Zero used pure reinforcement learning (RL) without relying on supervised fine-tuning (SFT), and while it demonstrated remarkable capabilities in reasoning benchmarks, it faced challenges such as poor readability and language inconsistencies. To counter these limitations, DeepSeek-R1 integrated cold-start data, reasoning-oriented RL, and SFT.
The development began with the collection of thousands of high-quality examples of long Chains of Thought (CoT), which formed the foundation for fine-tuning the DeepSeek-V3-Base model. During this cold-start phase, readability and coherence were prioritized to ensure user-friendly outputs. Subsequently, the model underwent a reasoning-oriented RL process using Group Relative Policy Optimization (GRPO). This innovative algorithm enhances learning efficiency by estimating rewards based on group scores rather than using a traditional critic model. This stage significantly improved the model’s reasoning capabilities, particularly in math, coding, and logic-intensive tasks.
Following RL convergence, DeepSeek-R1 underwent SFT with a dataset of approximately 800,000 samples, including both reasoning and non-reasoning tasks, broadening the model’s general-purpose capabilities and enhancing its benchmark performance. Furthermore, its reasoning capabilities were distilled into smaller models, like Qwen and Llama, enabling high-performance AI deployment in computationally efficient forms.
Technical Excellence and Benchmark Performance
DeepSeek-R1 has proved itself as a formidable AI model, excelling across multiple domains. In mathematics, DeepSeek-R1 achieved a Pass@1 score of 97.3% on the MATH-500 benchmark, comparable to OpenAI’s o1-1217, underscoring its ability to handle complex problem-solving tasks. On the Codeforces platform, DeepSeek-R1 achieved an Elo rating of 2029, placing in the top percentile. It also outperformed other models in benchmarks like SWE Verified and LiveCodeBench, proving itself a reliable tool for software development.
In reasoning benchmarks, DeepSeek-R1 scored 71.5% on GPQA Diamond and 79.8% on AIME 2024, demonstrating advanced reasoning capabilities with novel CoT reasoning and RL. Excelling beyond technical domains, it achieved an 87.6% win rate on AlpacaEval 2.0 and 92.3% on ArenaHard. Key features of DeepSeek-R1 include its architecture, which utilizes a Mixture of Experts (MoE) design with 671 billion parameters, activating only 37 billion parameters per forward pass, allowing for efficient computation and scalability, making it suitable for consumer-grade hardware. Its training methodology employs an RL-based training approach instead of traditional models’ SFT, enabling autonomous development of advanced reasoning capabilities, including CoT reasoning and self-verification.
Additionally, DeepSeek-R1’s cost efficiency is another standout feature, offering performance comparable to OpenAI’s o1 at approximately 95% lower cost. This cost efficiency could potentially alter the economic landscape of AI development and deployment, making advanced AI capabilities more accessible to a wider range of users and organizations. The ability to distill its reasoning capabilities into smaller models also means that it can be deployed on less powerful hardware without sacrificing performance, which is a significant advantage for many use cases.
OpenAI’s o1: A Proprietary Powerhouse
OpenAI’s o1 models are renowned for their state-of-the-art reasoning and problem-solving abilities, developed through large-scale SFT and RL to refine their reasoning capabilities. The o1 series excels at CoT reasoning, which involves breaking complex tasks into manageable steps. This approach has led to exceptional mathematics, coding, and scientific reasoning performance. One of the main strengths of the o1 series is its focus on safety and compliance, implemented through rigorous protocols including external red-teaming exercises and ethical evaluations, ensuring alignment with ethical guidelines suitable for high-stakes applications. The o1 series is also highly adaptable across diverse applications, including creative writing, conversational AI, and multi-step problem-solving.
Key features of OpenAI’s o1 include its model variants, which include three versions: o1, o1-mini, and o1 pro mode. The o1 family includes the full version with advanced capabilities, a smaller, more efficient model optimized for speed while maintaining strong performance, and the most powerful variant, utilizing additional computing resources for enhanced performance. In terms of performance benchmarks, the o1 pro mode scored 86% on the American Invitational Mathematics Examination (AIME), significantly outperforming the standard o1, which scored 78%. In coding benchmarks such as Codeforces, o1 models achieved high rankings, indicating strong coding performance.
The o1 models also boast multimodal capabilities, handling text and image inputs to enable comprehensive analysis and interpretation of complex data. This makes them highly versatile across various applications. Additionally, features like self-fact-checking improve accuracy and reliability, particularly in technical domains like science and mathematics. Enhanced bias mitigation and improved content policy adherence ensure safe and appropriate responses, achieving a not-unsafe score of 0.92 on the Challenging Refusal Evaluation. These safety features make the o1 series a robust choice for high-stakes applications where reliability and ethical compliance are paramount.
A Comparative Analysis: DeepSeek-R1 vs. OpenAI o1

In contrast, OpenAI o1’s strength lies in its multimodal capabilities and advanced safety measures, which ensure reliable and ethical outcomes across various applications.
The Open-Source vs. Proprietary Debate
The emergence of DeepSeek-R1 has reignited the debate over the merits of open-source versus proprietary AI development. Proponents of open-source models argue they accelerate innovation by pooling collective expertise and resources. They also promote transparency, vital for ethical AI deployment. In contrast, proprietary models often claim superior performance due to their access to proprietary data and resources. This competition between the two paradigms represents broader challenges in the AI landscape: balancing innovation, cost management, accessibility, and ethical considerations.
Following DeepSeek-R1’s release, Marc Andreessen notably tweeted, “Deepseek R1 is one of the most amazing and impressive breakthroughs I’ve ever seen — and as open source, a profound gift to the world.” His words underscore the potential of open-source models to democratize access to advanced AI capabilities and drive innovation.
Proprietary models, however, argue that the resources and funding available exclusively to them enable the development of more advanced and reliable AI systems. They claim that the control over the data and training processes ensures higher performance and safety standards. This stance emphasizes the importance of funding and resource allocation in achieving state-of-the-art AI outcomes.
