We identify the Flow Moment, a new confident reasoning format in LLM reasoning, and we explore the influence of this format on On-Policy Self-Distillation (OPSD). We propose Aha-Flow Distillation, a dual-mode extension of OPSD that combines Aha branch and Flow branch to distill the student model. This training on Qwen3-8B model only takes ~30 minutes on 8×H20 and peaks within 100 steps.
