Model releases, technical reports, and open weights from the Viggle research team.
JST-2 Character: 3D characters with motion built in
One image in, a complete full-body 3D character out, ready to animate without separate rigging and skinning steps.
JST-2 Motion: full-body 3D motion from text or video
Full-body 3D motion from text or video, applied directly to JST-2 characters without a separate retargeting step.
Meridian: A new perspective on space and time
A geometry-guided video model for authoring new observations of existing events: revisit a recorded moment from a new viewpoint, retime the action, and move the camera along a path you choose.
Viggle-Animate: Character Replacement in Video from a Single Repainted Frame
Open weights for a model that replaces the character in a video using one of its own frames, repainted. No pose skeleton, mask or prompt at video inference — 124 frames in 26 seconds on one GPU.
