MiniMax-H3 4-Step LoRA (FlashGen)
4-step distilled LoRA for MiniMax-H3 text-to-video+audio (T2VA). Trained on Ascend NPU with data-free distillation; merge into the base model and inject base_schedule before vllm-omni / MindIE-SD deployment.

./minimax-h3-4step-flashgen
export MODEL=./minimax-h3-4step-flashgen/FL2VA
