MiniMax Claims Its Open-Source Video Model Nearly Matches Closed-Source Physics

MiniMax H3 is positioned as the best open-source video world model for physics consistency, closing the gap with proprietary systems on a notoriously hard problem.

Physics remains the hardest thing for generative video to get right, which is exactly why MiniMax is claiming ground there. @MiniMax_AI touted its H3 model as the best open-source video world model for physics, saying it's "almost on par with closed-source sota." Physical consistency — objects that fall, collide, and move the way real ones do — is where generative video most visibly breaks down, so it's a meaningful benchmark to compete on.
