History Forcing is a unified on-policy distillation framework for few-step autoregressive video generators. It uses the residual between teacher predictions with and without informative history to correct the score or velocity target used for distillation, improving long-video consistency and out-of-sight scene evolution.

Checkpoint	Model
opsd/model.pt	DreamX-World-5B
dmd/model.pt	Wan2.1-T2V-1.3B, raw and EMA
ar_teacher/model.pt	Wan2.1-T2V-1.3B AR teacher

The released DMD checkpoint was trained with a 1.3B bidirectional teacher and the 10-second AR teacher.

Inference and training are available in the code.
