LTX 2 VBVR LoRA Video Reasoning LoRA fine tuned weights for LTX 2.3 22B on the VBVR (A Very Big Video Reasoning Suite) dataset. Training Data To ensure training quality, we preprocessed the full 1,000,000 videos from the official dataset and randomly sample during training to maintain data diversity. We adopt the official parameters with batch size=16 and rank=32 to prevent catastrophic forgetting caused by excessively large rank. The VBVR dataset contains 100 reasoning task categories, with ~10,000 variants per task, totaling ~1M videos. Main task types include: Object Trajectory : Objects moving to target positions Physical Reasoning : Rolling balls, collisions, gravity Causal Relationships : Conditional triggers, chain reactions Spatial Relationships : Relative positions, path planning Model Details Item Details Base Model ltx 2.3 22b dev Training Method LoRA Fine tuning LoRA Rank 32 Effective Batch Size 16 Mixed Precision BF16 TODO List Dataset Release Plan Dataset Videos Status VBVR 96K 96,000 ✅ Released VBVR 240K 240,000 ✅ Released VBVR reinforce 240K+150K ✅ Released LoRA Capabilities This LoRA adapter enhances the base LTX 2 model for production video generation workflows: E…
