Running MiniMax H3 on RTX 4060Ti: 40 Minutes for a 5-Second Video
nortonanand · reddit · 2026-08-05
A user shared performance metrics for running the MiniMax H3 (FL2VA pruned bf16) video generation model locally on an RTX 4060Ti 16GB.
The test revealed that generating a 5-second video at 1920x1088 resolution took approximately 2,420 seconds (40 minutes), utilizing Spectrum and Sage Attention optimizations. This highlights the current computational cost of open-source video models on consumer hardware.
