给 AI 一张陶罐碎片图，它能还原破裂过程吗？Minimax H3 vs Seedance 2.0 Fast 实测

TL;DR - A hands-on comparison tests MiniMax H3 and Seedance 2.0 Fast on reconstructing a pottery-breaking sequence from a final-state image. Seedance delivered faster, more realistic physics, while H3 demonstrated the research and customization value of locally deployable open weights.

• H3 generated a coherent causal sequence using reference-image conditioning, text instructions, and joint audio-video generation.
• Seedance completed a 10-second video in 3m23s versus H3’s 54m04s on an RTX A6000, though hardware and optimization differences limit direct performance comparisons.
• Seedance showed clearer contact, falling, fragmentation, and settling; H3’s key collision and audio details were less convincing.
• H3 is not fully open source: some modules remain unavailable locally and require MiniMax’s API for complete capabilities.
