Rectified Flow: Straightening Paths Toward 1-Step Generation
Flow Matching still too slow? Reflow straightens trajectories for 1-step generation. The core technique behind SD3 and FLUX.
Rectified Flow: Straightening Paths Toward 1-Step Generation
Flow Matching still too slow? Reflow straightens trajectories to enable 1-step generation.
TL;DR
- Rectified Flow: Iteratively "straightens" Flow Matching trajectories
- Reflow: Generate (noise, data) pairs with learned model, then retrain on straight-line paths
