Fal Engineer Criticizes 'Fake' Video Model Speedups: Quality Ignored
jfischoff · x · 2026-08-29
A Fal engineer criticized community practices that prioritize speed over quality, noting some optimizations claim massive speedups while producing outputs unrelated to the original model—essentially generating random pixels. He emphasized that image/video models are notoriously hard to optimize, and his team spends 2-3x more time on evals than on kernel engineering to ensure validity. The context involves the release of MiniMax/Haoai's FastH3 v1, which sparked debate over sacrificing quality for speed.
