⬤ Apple researchers published a study that shows a single attention layer turns frozen vision features into strong image generators. Their paper of 8 December 2025 presents a Feature Auto-Encoder that re uses existing visual encoders instead of training new ones.
⬤ The method addresses a core problem in generative modelling - the gap between understanding pictures and creating them. Standard diffusion models rely on deep, specialised networks that raise both training effort and compute cost.
⬤ FAE splits the task in two. A frozen encoder keeps its weights - a light decoder plus one attention layer handle reconstruction plus generation. The encoder structure stays intact - yet it now outputs images.
⬤ The team evaluated FAE on CIFAR-10 LSUN ImageNet and text-to-image tasks. With fewer training steps it matched or surpassed standard diffusion results indicating that future systems can recycle existing representations instead of growing ever larger.
