Key points
- It performs real-time 720p generation at 24 fps using LTX-2.3 fine-tuning, with four denoising steps per chunk for about one second of video.
- Prompt switching updates the text condition at chunk boundaries to support open-ended actions.
- A 3D cache plus history compression preserves spatial consistency and demonstrates leave-and-return consistency.
- The error bank stabilizes long-horizon generation by reusing residual artifacts accumulated during rollout as structured perturbations.
- Few-step DMD distillation minimizes visual latency, while short chunks minimize semantic latency.
- The full stack, from data preparation to training, inference acceleration, and deployment, is modularized and planned for open-source release.
