Preventing Curriculum Collapse in Self-Evolving Reasoning Systems

Researchers introduce Prism, a new self-evolving AI reasoning system that prevents diversity collapse in problem generation by maintaining semantic coverage across mathematical problem spaces. The system achieved significant accuracy improvements over existing methods on mathematical reasoning benchmarks and generated 100k diverse mathematical questions.

Where does output diversity collapse in post-training?

Researchers discover that post-trained language models experience systematic output diversity collapse, where fine-tuning methods reduce the variety of generated responses compared to base models. This collapse is determined during training by data composition choices and cannot be fixed through inference-time adjustments, with implications for scaling methods and creative AI applications.
