Thinking Leakage: A Causal Audit of NoThink Post-Training in Hybrid Reasoning Models
arXiv:2609.28682v1 Announce Type: new Abstract: Post-training hybrid reasoning models in NoThink mode has attracted growing interest as a way to improve performance while keeping inference fast. However, these gains may draw on thinking behavior already accessible through the base model's Think mod…
