Sol-H3: MiniMax-H3 video generation faster than playback at 1.653s per 5s clip on 8x B300
MiniMax_AI · x · 2026-09-08
NVIDIA's Sol team and MiniMax released Sol-H3, their fastest end-to-end MiniMax-H3 inference stack. On a single 8x B300 Blackwell system it generates 5 seconds of 1344x768 video with stereo audio in 1.653 seconds — faster than playback. Versus 50-step Base H3 Dense on the same system: 5s clips go 18.250s→1.653s (11.04x), 10s 50.660s→3.732s (13.57x), 15s 99.513s→6.612s (15.05x). It scales across GPU counts (4x B300: 2.918/6.993/12.542s for 5/10/15s), reaching up to 15.54x speedup. Fully open-sourced and available via the Reactor API sandbox.
