AcFlow: Controlling Text-to-Image Diffusion Transformers via Learned Conditional Activation Flow
AcFlow is introduced, an inference-time controller that transports intermediate layer image-token activations through a learned concept-conditioned velocity field while keeping the base DiT frozen, and supports the learned velocity field as an adaptive control mechanism.
