Diffusion Controller: steering damper for AI image generation
Google Research introduces Diffusion Controller, a lightweight steering-damper side network that steers image generation and can attach to closed-source models to improve prompt alignment.
What changed
Introduced Diffusion Controller: a lightweight steering-damper side network attachable to closed-source models; evaluated on Stable Diffusion v1.4 with HPS-v2; white-box fine-tuned version recorded a 90% win rate over the baseline.
Why it matters
Developers can steer outputs toward user intent without modifying large pretrained backbones; creators and researchers can control closed-source models and adjust guidance at inference time.

Worth trying
Maybe — Depends on access to model internals or ability to attach a side network.
