On-policy distillation offers dense, per-token supervision for training reasoning models; however, it remains unclear under which conditions this signal is beneficial and under which it is detrimental. Which teacher model should be used, and in the case of self-distillation, which specific context should serve as the supervisory signal? Does the optimal choice vary from one token to the next? At present, addressing these questions typically requires costly training runs whose aggregate performance metrics obscure the dynamics at the level of individual tokens. We introduce a training-free…
The proliferation of reasoning models and the inherent complexity of their training necessitate more efficient and effective distillation techniques, making this research timely for improving AI development.
Understanding the precise conditions under which on-policy distillation is beneficial or detrimental is critical for optimizing the training of advanced AI models, impacting efficiency and performance.
The ability to unmask the internal dynamics of on-policy distillation 'without costly training runs' could significantly accelerate AI research and model development by providing a clearer feedback mechanism.
