- 12026-08-04[Benchmark] Running MiniMax-H3 on one RTX 5090: four files, 31.7 GB, 175s per talking clip
Beginner walkthrough for MiniMax-H3, the 33B model that generates video and stereo audio in one pass. Full precision is 115 GB; quantized it fits one RTX 5090. What to download, where it goes, how to prompt it.
- 22026-08-06[Benchmark] Twice as Fast: MiniMax-H3 on an RTX 5090, 625s Down to 314s
Three stacked changes took a 15-second 1080p MiniMax-H3 render from 625s to 314s on one RTX 5090: 14 steps, SageAttention 2.2.0, and RTX VSR replacing Real-ESRGAN.
- 32026-08-23[Benchmark] MiniMax-H3 1080p Isn't Unsupported, It's Three and a Half Hours
Three mistakes shooting a wuxia scene in MiniMax-H3: a 502 that wasn't a rejection, blur upscaling can't fix, and a prompt that described a face instead of naming one.
- 42026-08-31[Benchmark] Ten effect embeddings for MiniMax-H3 — 10 MB that buys you bullet time, fire breath and a full year of seasons
Ten community effect embeddings for MiniMax-H3, tested at native 1344x768 on one RTX 5090. What each one actually does, the prompt shape that lets them work, and the placement rule that decides whether they fire at all.
- 52026-09-03[Benchmark] From OOM to 8.6 minutes: a MiniMax-H3 config stack for one RTX 5090
MiniMax-H3 at native 1344x768 on a single RTX 5090: 15 seconds of video in 518 s. What KJNodes chunking, torch cu130 and the NVFP4 kernels are each worth.
