OpenWAM-Alpha-Sim-RoboDojo

OpenWAM-α applies the recipe selected by the OpenWAM study: a Wan2.2-TI2V-5B video backbone with its native Wan-VAE encoder, a Dual-System Joint Self-Attention architecture, and a mutual attention mask. It is pretrained on 518.5M frames (about 6,400 hours), mixing robot data (70%: 40% real-world, 30% simulation) with egocentric human data (30%).

Finetuned on the RoboDojo simulation track.
