ReWorld: An Interactive World Model with Long-Horizon Memory
arXiv cs.AI · Published · 3 min read

- What happened
- ReWorld is an interactive world model that maintains long-horizon memory while responding to user actions in real time, streaming photorealistic video across multiple environments.
- Why it matters
- Relevant for engineers building interactive simulations, game engines, or video generation systems requiring both responsive control and persistent scene memory.
- Watch out
- The approach uses a fixed 12-chunk KV cache with pose-indexed retrieval, which may not scale to arbitrarily large or complex environments beyond the tested scenarios.
