Running MiniMax Video Model on RTX 5090 Uses Only 20GB VRAM
BoredHobbes · reddit · 2026-08-14
A developer running MiniMax's video generation model locally on an RTX 5090 (32GB VRAM) noticed that regardless of settings, the model maxes out at 20GB VRAM, whereas the LTX model utilizes 30GB. The included logs indicate that the ComfyUI environment has enabled async weight offloading and pinned memory optimizations, which likely explains the unusually low VRAM footprint.
