MiniMax H3 Fast Master: Gold Standard Execution Skill

Questa skill definisce la formula ingegneristica d'oro per la generazione video con MiniMax H3 / H3-Max su Apple Silicon M5 Max, testata e validata come la massima combinazione di qualità fotorealistica (macro ottica 8k) e velocità estrema (Denoise GPU in 6-10s su 1s e 36-44s su 4s).
