Fragmented guidance methods hinder principled optimization
Current inference-time guidance and fine-tuning techniques—such as classifier-free diffusion guidance, LoRA, reward-weighted regression, and policy gradients—are used in isolation. This fragmentation has prevented development of a unified mathematical framework for controlling generative models, leaving engineers to balance prompt alignment and image quality through trial and error.

How Diffusion Controller unifies and simplifies AI image generation
Original excerpt
Because these tools have historically been treated as distinct and unrelated fixes, the field has lacked a single, principled mathematical language to unify, analyze, and optimize how we control generative models. This fragmented approach often forces engineers to rely on guesswork when balancing user preference alignment against image quality.
