AvatarForcing is a **one-step streaming diffusion** framework for talking avatars. It generates video from **one reference image + speech audio + (optional) text prompt**, using **local-future sliding-window denoising** with **heterogeneous noise levels** and **dual-anchor temporal forcing** for long-form stability. For method details, see: https://arxiv.org/abs/2603.14331

|
| 31 |
+
- `ode_audio_init.pt`: stage-1 **ODE** initialization weights
|
| 32 |
+
- `model.pt`: stage-2 **DMD** weights
