SGF+: Decoupling Gradient Flows for Autoregressive Video Generation

Zihan Su, Junhao Zhuang, Yaowei Li وآخرون · 2026

Autoregressive video generation requires denoising the current frames while writing their key-value representations as context for future predictions. However, these two roles typically share parameters, and we find that their gradients exhibit distinct patterns and systematic negative alignment, hindering the joint op …

Shallow Queries, Mature Values: Depth-Asynchronous Self-Speculation for Looped Transformers

Guanghao Li, Zihan Su, Hao Yu وآخرون · 2026

Looped Transformers reuse a shared block across recurrent depths, making autoregressive decoding expensive because every generated token requires many sequential recurrent passes. Self-speculative decoders reduce this cost by drafting at an early depth and verifying at full depth, but typically bind draft computation t …

Where and When to Force: Routed Forcing for Streaming Avatars

Zihan Su, Siwen Lu, Junhao Zhuang وآخرون · 2026

Audio-driven streaming avatar generation requires real-time synthesis of speech-synchronized videos with dynamic and diverse motion. Self Forcing uses Distribution Matching Distillation (DMD) to distill bidirectional video diffusion models into causal, few-step generators for real-time streaming. However, DMD minimizes …
