An AI filmmaker benchmarked Sage Attention across multiple video models on an RTX 4060 Ti 16GB setup.
- MiniMax H3: Render time dropped from 15m 01s to 9m 22s, a 38% speedup. This makes H3, which excels at natural movement, practical for hero shots.
- Krea 2: Render time went from 63.42s to 61.44s, only a 3% improvement.
- LTX2.3: Showed no advantage or even slight slowdown with Sage Attention.
Based on the results, the author established a new workflow: using LTX2.3 for fast establishing shots and coverage, and MiniMax H3 for hero shots requiring natural acting.
