Researchers have developed new methods for guiding generative models, particularly in text-to-image synthesis. One approach, Flow Map Reward Guidance (FMRG), reformulates guidance as an optimal control problem and uses a flow map for efficient, single-trajectory integration and guidance, achieving significant speedups and matching or surpassing existing methods with fewer steps. Another method, LeapAlign, addresses the computational challenges of fine-tuning flow matching models by shortening long trajectories into two leaps, enabling efficient and stable updates at any generation step and outperforming current state-of-the-art techniques in image quality and alignment. Additionally, a separate paper explores constraint-aware flow matching, proposing adaptations to penalize distance from constraint sets or use randomization for scenarios where constraint sets are only queryable.
