A 33-billion-parameter model from Chinese AI firm MiniMax has taken the top spot in the Video Edit Arena on arena.ai, scoring 1390 points and opening a 32-point gap over its closest competitors, Dreamina Seedance 2.0 and Gemini Omni Flash. The model, called MiniMax-H3, launched on July 31, 2026, and needed roughly two weeks to climb to the number one position.
It’s also the first open-weight model to dominate a video editing category on the Artificial Analysis leaderboards. The weights are hosted on Hugging Face, though access is restricted for US individuals and certain other users.
What MiniMax-H3 actually does
MiniMax-H3 is what the industry calls an “omni-modal” video generation model. You feed it text, images, videos, audio, or some combination of all four, and it produces 2K-resolution video clips ranging from 4 to 15 seconds with synchronized stereo sound baked in.
A single prompt can reference up to 9 images, 3 videos, and 3 audio files simultaneously. That level of multi-input flexibility is a big part of why the model excels at instruction-based editing tasks like subject replacement and relighting.
