Two insights from LeapAlign: 1. Gradient descent, rather than GRPO, is native to diffusion post-training. 2. Early generation steps should be trained, such that image layout can be better optimized. Thanks @hillbig for posting this work.
Across 21 recent diffusion methods, improvements on ImageNet did not predict text-to-image improvements under identical DiffusionBench settings
Diffusion is differentiable. LLMs aren't. So why is the diffusion community copying RL methods (GRPO etc.) from LLMs? The native post-training for diffusion is gradient descent such as ReFL and LeapAlign. Paper: http:// arxiv.org/abs/260
