Generative AI Performance in Elite Japanese University Entrance Exams

Introduction

The AI company LifePrompt Inc. reported on April 27 that OpenAI's ChatGPT 5.2 Thinking model scored higher than the top human candidates in the 2026 entrance exams for the University of Tokyo and Kyoto University.

Main Body

To test the AI, the company converted exam questions into images. To ensure the essay answers were graded fairly, educators from the Kawai Juku preparatory school performed the evaluations. At the University of Tokyo, the model scored 503 out of 550 points in the Natural Sciences III medical track, beating the top human score of 453 by 50 points, and achieved a perfect score in mathematics. In the Humanities and Social Sciences exam, the AI scored 452 out of 550, which was higher than the top successful applicant's score of 434. Similarly, at Kyoto University, the model outperformed the top human scores in both the Faculty of Law and the Faculty of Medicine. However, the AI's performance varied depending on the subject. While it achieved a 90% accuracy rate in English, it only scored 25% on World History essay questions. These results show a major improvement in AI capabilities. Previous versions tested by LifePrompt in 2024 failed to pass, while the 2025 model was the first to reach the minimum passing score. Experts have different opinions on what these results mean for human intelligence and education. Satoshi Endo, head of LifePrompt, asserted that the rapid development of AI means businesses must change their long-term strategies over the next twenty years. On the other hand, Satoshi Kurihara, a professor at Keio University, criticized the comparison between humans and AI. He argued that because AI can absorb massive amounts of data, it is like a calculator. Consequently, he emphasized that universities should rethink exams that focus on memory and calculation rather than the ability to create original value.

Conclusion

In summary, while generative AI has outperformed humans in standardized tests and knowledge-based questions, it still faces challenges in specific areas of qualitative essay writing.
