Running MiniMax Video Model Locally: M3 Ultra Takes 2.6 Hours for 10s Video

cocktailpeanut · x · 2026-08-05

A developer has successfully run MiniMax's video generation model locally on a Mac powered by an M3 Ultra chip.

Test Parameters: Resolution set to 1280x768, 20 inference steps, generating a 10-second video.
Performance: The entire generation process took approximately 2 hours and 39 minutes.
Outlook: The author noted that while future M5 Max chips might offer speed improvements via NAX, the reduction in core count (from 80 to 40) means overall performance gains may be limited.
