Sol-H3 runs MiniMax video gen faster than playback: 5s video in 1.653s on 8× B300
teortaxesTex · x · 2026-09-08
Sol-H3, a new end-to-end inference stack for MiniMax-H3 built with NVIDIA, generates 5 seconds of 1344×768 video with stereo audio in 1.653 seconds on a single 8× NVIDIA B300 Blackwell system — faster than playback.
- vs. 50-step Base H3 Dense on 8× B300: 5s clip 18.250s→1.653s (11.04×), 10s 50.660s→3.732s (13.57×), 15s 99.513s→6.612s (15.05×)
- Scales across GPUs: 4× B300 does 5s/10s/15s in 2.918s/6.993s/12.542s; speedups up to 15.54×
A four-step sampling profile replaces the 50-step baseline. NVIDIA-affiliated commenters hail it as proof of the OSS flywheel: release a model, and the community returns a 10x speedup within weeks.
