Self-Distillation Zero: Self-Revision Turns Binary Rewards into Dense Supervision

Researchers have introduced Self-Distillation Zero (SD-Zero), a method that enhances model training efficiency by converting binary rewards into dense token-level supervision without needing an external teacher or high-quality demonstrations. This technique, tested on math and code reasoning benchmarks, outperforms existing methods like Rejection Fine-Tuning and GRPO, offering significant performance improvements for developers working with limited training data.
