+# HyDRA: Out of Sight but Not Out of Mind: Hybrid Memory for Dynamic Video World Models
+
+This is the official Hugging Face model repository for **HyDRA** (Hybrid Memory for Dynamic Video World Models). 
+
+🔗 **GitHub Repository:** [H-EmbodVis/HyDRA](https://github.com/H-EmbodVis/HyDRA)
+📄 **Project Page:** [Hybrid-Memory-in-Video-World-Models](https://kj-chen666.github.io/Hybrid-Memory-in-Video-World-Models/)
+
+## 🔍 Overview
+
+While recent video world models excel at simulating static environments, they share a critical blind spot: the physical world is dynamic. When moving subjects exit the camera's field of view and later re-emerge, current models often lose track of them. 
+
+To bridge this gap, we introduce **Hybrid Memory**, a novel paradigm that requires models to simultaneously act as precise archivists for static backgrounds and vigilant trackers for dynamic subjects. **HyDRA** is a specialized memory architecture that compresses contexts into memory tokens and utilizes a spatiotemporal relevance-driven retrieval mechanism.
+
+## 🎯 Task & Capabilities
+- **Task:** Text-to-Video Generation / Video World Modeling
+- **Input:** Text prompts, camera poses, and initial video latents.
+- **Output:** High-fidelity video sequences maintaining both identity and motion continuity of dynamic subjects, even during out-of-view intervals.
