DeepSeek-R1 vs. OpenAI’s o1: A New Step in Open Source and Proprietary Models

AI has entered an era of the rise of competitive and groundbreaking large language models and multimodal models. The development has two sides, one with open source and the other being propriety models. DeepSeek-R1, an open-source AI model developed by DeepSeek-AI, a Chinese research company, exemplifies this trend. Its emergence has challenged the dominance of proprietary models such as OpenAI’s o1, sparking discussions on cost efficiency, open-source innovation, and global technological leadership in AI. Let’s delve into the development, capabilities, and implications of DeepSeek-R1 while comparing it with OpenAI’s o1 system, considering the contributions of both spaces.

DeepSeek-R1 is the great output of DeepSeek-AI’s innovative efforts in open-source LLMs to enhance reasoning capabilities through reinforcement learning (RL). The model’s development significantly departs from traditional AI training methods that rely heavily on supervised fine-tuning (SFT). Instead, DeepSeek-R1 employs a multi-stage pipeline combining cold-start, RL, and supervised data to create a model capable of advanced reasoning.

The Development Process

DeepSeek-R1 leverages a unique multi-stage training process to achieve advanced reasoning capabilities. It builds on its predecessor, DeepSeek-R1-Zero, which employed pure RL without relying on SFT. While DeepSeek-R1-Zero demonstrated remarkable capabilities in reasoning benchmarks, it faced challenges such as poor readability and language inconsistencies. DeepSeek-R1 adopted a more structured approach to address these limitations, integrating cold-start data, reasoning-oriented RL, and SFT.

The development began with collecting thousands of high-quality examples of long Chains of Thought (CoT), a foundation for fine-tuning the DeepSeek-V3-Base model. This cold-start phase emphasized readability and coherence, ensuring outputs were user-friendly. The model was then subjected to 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 using a dataset of approximately 800,000 samples, including reasoning and non-reasoning tasks. This process broadened the model’s general-purpose capabilities and enhanced its performance across benchmarks. Also, the reasoning capabilities were distilled into smaller models, such as Qwen and Llama, enabling the deployment of high-performance AI in computationally efficient forms.

Technical Excellence and Benchmark Performance

DeepSeek-R1 has established itself as a formidable AI model, excelling in benchmarks across multiple domains. Some of its key performance highlights include:

• Cost Efficiency: DeepSeek-R1 is reported to deliver performance comparable to OpenAI’s o1 at approximately 95% lower cost, which could significantly alter the economic landscape of AI development and deployment.

OpenAI’s o1 models are known for their state-of-the-art reasoning and problem-solving abilities. They were developed by focusing on large-scale SFT and RL to refine their reasoning capabilities. The o1 series excels at CoT reasoning, which involves breaking down complex and detailed tasks into manageable steps. This approach has led to exceptional mathematics, coding, and scientific reasoning performance.

A main strength of the o1 series is its focus on safety and compliance. OpenAI has implemented rigorous safety protocols, including external red-teaming exercises and ethical evaluations, to minimize risks associated with harmful outputs. These measures ensure the models align with ethical guidelines, making them suitable for high-stakes applications. Also, the o1 series is highly adaptable, excelling in diverse applications ranging from creative writing and conversational AI to multi-step problem-solving.
