A zero-cost curvature proxy predicts Euler step error for flow matching, but per-sample step control adds nothing over a static grid (Anima, 12 units; related to CAT-Flow) [R]
Question. A multistep sampler has consecutive velocity evaluations for free. Is the angle between them a usable curvature signal for adaptive stepping, and does using it online beat a fixed grid? Setup. Anima (flow model, bf16), 576x768, CFG 5, 4 prompts x 3 seeds = 12 units. Reference: Adams-Bashf…
