Unified Progressive Frequency Bridging

Lumos-Nexus: Efficient Frequency Bridging for Reasoning-Driven Video Generation

Lumos-Nexus is a training-efficient unified video generation framework that decouples training and inference to achieve high visual fidelity without prohibitive compute costs. During training, a lightweight generator is aligned with an understanding block; at inference, Unified Progressive Frequency Bridging (UPFB) hands off generation to a high-capacity pretrained generator in a shared latent space for coarse-to-fine refinement. The authors also introduce VR-Bench, a new benchmark for evaluating reasoning-driven video generation. Code and models are publicly released.
