arXiv:2605.24998v1 Announce Type: new Abstract: Self-improvement training enables the large reasoning models (LRMs) to improve themselves by self-generating reasoning trajectories as training data without external supervision. However, we find that this method often falls short in complex reasoning tasks and even leads to model collapse. Through a series of preliminary analyses, we reveal two problems: (1) data imbalance, where most training samples are simple, but the challenging yet crucial samples are scarce; (2) overthinking, where many undesired samples with redundant reasoning steps are
The rapid advancement and deployment of large reasoning models necessitate continuous improvement strategies, leading researchers to identify and address bottlenecks in self-improvement methods.
Improving the self-improvement capabilities of AI models is crucial for their scalability, autonomy, and ability to handle complex, real-world problems without constant human oversight.
The understanding of critical limitations in current self-improvement training for large reasoning models changes expectations for their immediate autonomous capabilities and points towards necessary research directions for more robust AI agents.
