Abstract: Controllable face generation poses critical challenges in generative modeling
due to the intricate balance required between semantic controllability and
photorealism. While existing approaches struggle with disentangling semantic
controls from generation pipelines, we revisit the architectural potential of
Diffusion Transformers (DiTs) through the lens of expert specialization. This
paper introduces Face-MoGLE, a novel framework featuring: (1)
Semantic-decoupled latent modeling through mask-conditioned space
factorization, enabling precise attribute manipulation; (2) A mixture of global
and local experts that captures holistic structure and region-level semantics
for fine-grained controllability; (3) A dynamic gating network producing
time-dependent coefficients that evolve with diffusion steps and spatial
locations. Face-MoGLE provides a powerful and flexible solution for
high-quality, controllable face generation, with strong potential in generative
modeling and security applications. Extensive experiments demonstrate its
effectiveness in multimodal and monomodal face generation settings and its
robust zero-shot generalization capability. Project page is available at
