PIXIO Report: Doubles Open Video Model Speed on Single 96GB GPU
tsi_org · x · 2026-08-10
PIXIO Research released a technical report demonstrating how engineering optimizations doubled the speed of open-weight video generation models.
- Model: MiniMax H3 (open-weights video model with native stereo audio)
- Hardware: Single 96GB workstation GPU
- Performance: 15-second clip render time reduced from 8.2 to 5.6 minutes (32% faster); 5-second clips take 1 minute; 30-second clips reduced from 21 to 10 minutes (2.1x faster).
- Mechanism: Optimizations target the attention cost, which grows quadratically with sequence length, achieving gains while maintaining the exact same weights and quality bar.
