MiniMax-H3 — sampling steps vs cache stride · blind

13 categories × 3 arms. Every clip is 1344×768, 243 frames (10.1 s), seed 12345, SageAttention 2, FBCache 0.10, one RTX 5090 — the arms differ only in step count and cache stride. The arms diverge in content, not just quality: a different schedule walks a different path from the same seed, so clips show different actions. That is a free choice, not a defect — judge each clip on whether you would ship it, not on whether it matches the others. Order is shuffled per category and identities are hidden; pick first, then reveal.
