New On-Policy Delta Distillation method enhances LLM reasoning capabilities

By PulseAugur Editorial · [2 sources] ·

Researchers have introduced a novel method called On-Policy Delta Distillation (OPD^2) to improve the transfer of reasoning capabilities in large language models. This technique utilizes a "delta signal," which represents the difference between a teacher model and its base model before instruction tuning, to provide more direct supervision. Experiments across mathematics, science, and code-reasoning tasks show that OPD^2 significantly outperforms conventional on-policy distillation, enabling LLMs to achieve strong reasoning performance with minimal post-training.
