We introduce Diffusion Controller, a lightweight "steering damper" network that precisely steers image generation to achieve significantly better prompt alignment. It seamlessly attaches to even access-restricted, closed-source models, boosting image quality without breaking baseline stability. Quick links The rapid advancement of text-to-image AI models, such as Nano Banana , Stable Diffusion and Flux , has fundamentally transformed creative design, allowing anyone to synthesize photorealistic, high-fidelity images from textual descriptions. However, steering these massive models to meet precise user intent, downstream goals, or strict visual constraints remains a delicate and unpredictable balancing act. For example, imagine prompting a model for "a lizard wearing sunglasses". The model might generate a realistic lizard that's not wearing sunglasses. Alternatively, forcing the model to include the sunglasses might distort the lizard's face, ruining the image quality. Existing methodologies that guide or fine-tune image generation are very disconnected. …
