Flow Matching & Rectified Flows
Diffusion models take 20-50 sampling steps because they walk a curved path from noise to data. Flow matching (Lipman et al., 2023) and rectified flow (Liu et al., 2022) trained straight paths. Straighter paths mean fewer steps mean faster inference. Stable Diffusion 3, Flux.1, and AudioCraft 2 all switched to flow matching in 2024.
Visual edition planned
This lesson isn’t interactive yet.
It is part of the curriculum and will get the same treatment as Phase 1 — a visual cover, hands-on labs, derivations with numeric checks and a quiz. Until then, the original lesson is the best place to read it:
