Researchers have developed HACHIMI, a novel multi-agent framework designed to generate scalable and controllable student personas for educational large language models. This system addresses limitations in prior methods by aligning persona generation with educational theory and enabling control over population distributions. The framework produces a corpus of 1 million personas, HACHIMI-1M, which has been evaluated for schema validity, quota accuracy, and diversity, showing strong alignment in math and curiosity constructs but moderate alignment in classroom climate and well-being.
