Researchers have developed two novel frameworks, DIDR and RTDMD, to improve the alignment of text-to-image generation models with human preferences. DIDR, or Diff-Instruct with Diffused Reward, is a data-free framework that optimizes reward across all noise levels in diffusion trajectories, enhancing image fidelity. RTDMD, a two-stage approach, combines distribution matching distillation with reward-guided reinforcement learning for few-step generators. Both methods demonstrate significant improvements in preference, aesthetic, and compositional metrics, with RTDMD achieving state-of-the-art results on models like SD3, SD3.5, and FLUX.2 using only a few inference steps.
