Two new papers explore advanced self-distillation techniques for large language models, aiming to improve reasoning and efficiency. The first paper introduces "Power Distribution Bridges," which connects sampling, self-reward RL, and self-distillation, showing that the power distribution can optimize KL-regularized RL and enable a new form of offline distillation. The second paper proposes "Preference-Based Self-Distillation" (PBSD), moving beyond simple KL matching to a reward-regularized objective that optimizes preference gaps, leading to improved training stability and performance on reasoning and tool-use benchmarks.
