Questioning the Questions: Sustaining Self-Evolution in Reasoning Models

Jinyuan Li, Chengsong Huang, Langlin Huang et al.1 min readHugging FaceOct 3, 2026

Key Takeaway for Students

Self-evolving reasoning models learn from their own generated questions, yet repeated self-training can lead to performance collapse. In this paper, we investigate why performance deteriorates over successive rounds and how to sustain self-evolution. Our analysis identifies two recurring quality problems in self-generated questions: invalid questions and repeated variants of th

Why it matters

This research is crucial for ML engineers working on self-improving AI systems, as it highlights common pitfalls in self-training loops that can lead to performance degradation. Understanding these issues is vital for building robust and continuously evolving reasoning models, preventing the accumulation of low-quality data. It provides insights into sustaining model performance over long-term self-evolution, which is key for developing more autonomous and reliable AI agents.
