CAT-Flow: Curvature-Adaptive sTeps for Flow Matching
Two lightweight, training-free algorithms are proposed, CAT-OV and CAT-OT that adapt step-sizes at inference time based on a novel connection between Flow Matching sampling and gradient flow that outperform existing step-size heuristics in image quality metrics across four text- to-image Flow Matching models.
