Light Origins open-sources 6B-parameter Light-O1-Preview whole-body model

Light Origins has open-sourced Light-O1-Preview, a roughly 6-billion-parameter whole-body action model released under Apache 2.0 on Hugging Face and GitHub. Pretrained on human actions recovered from video, it outputs whole-body motion at 20 fps and reached a 79.3% macro success rate across 24 RoboCasa GR-1 simulation tasks.

• The ~6B-parameter checkpoint is published under Apache 2.0 on Hugging Face and GitHub
• It outputs motion at 20 fps with a 138-value-per-frame layout, 22 joints and hand states
• Pretraining spanned 3.75B to 120B multimodal tokens, up to ~100,000 hours of human action
• RoboCasa GR-1 simulations hit 79.3% success on 24 tasks, but a separate controller is needed
