Researchers have identified a phenomenon called factual access failure in large language models after supervised fine-tuning (SFT). This occurs when models can still recognize correct answers in constrained evaluations but fail to generate them in open-ended tasks. To combat this, a new method called Recall-Anchored Distillation (RAD) has been introduced. RAD uses a base-anchored self-distillation objective to maintain out-of-distribution generation behavior by aligning the adapted model with the original base model's soft continuation distribution on unlabeled text.
