4. Performance Comparison: DeepSeek vs ChatGPT

  • 4-1. Results on critical reasoning benchmarks

  • In a recent study published on June 20, 2025, DeepSeek's R1-0528 model was shown to outperform ChatGPT on critical reasoning benchmarks, particularly those requiring logical inference and mathematical problem-solving. DeepSeek achieved an impressive accuracy of 90.8% on the Massive Multitask Language Understanding (MMLU) benchmark, surpassing ChatGPT's accuracy of 86.4%. This indicates that DeepSeek's architecture, which utilizes a Mixture of Experts (MoE) framework, is more attuned to structured reasoning tasks. While ChatGPT excels in general-purpose applications, DeepSeek has solidified its position as a leader in reasoning-heavy scenarios. This contrasts with the broader capabilities of ChatGPT, which is designed for a wider range of uses but with relatively less focus on pure reasoning tasks.

  • 4-2. Analysis of operational cost differences

  • The operational costs associated with using DeepSeek are significantly lower than those for ChatGPT. According to the same study, the cost of inference for DeepSeek is approximately $2.19 per million tokens, which starkly contrasts with ChatGPT's $15 per million tokens. This cost efficiency is primarily attributed to DeepSeek's innovative training approach, which reported a development expenditure of around $6 million, compared to the over $100 million incurred by OpenAI for ChatGPT. The substantial differences in cost make DeepSeek a favorable option for enterprises and organizations that require high reasoning capabilities without the accompanying financial burden that ChatGPT entails.

  • 4-3. Assessment of conversational fluency limitations

  • Despite its strengths in reasoning and cost efficiency, DeepSeek's R1-0528 model faces challenges in conversational fluency. While it is engineered to tackle logical reasoning tasks and can deliver accurate outputs in specific domains, it struggles to match the engaging conversational style and adaptability of ChatGPT. ChatGPT has established a reputation for its ability to produce coherent, contextually aware responses across a variety of topics, making it the preferred choice for general chat functionalities and creative tasks. The study highlights that while DeepSeek is adept in its specialized areas, it may require users to adopt a more structured approach to inputs, which could limit its accessibility compared to ChatGPT's more user-friendly interface.
