About ReWorld
An interactive world model that streams explorable 704 × 1280 video while you drive the camera with keyboard and mouse. A window-split training scheme decouples precise action following from long-horizon memory, and inference pairs a bounded KV cache with a pose-indexed landmark bank so GPU memory stays constant while revisited places retrieve the right past views. The 5B model is distilled to four denoising steps and trained on metric-aligned multi-source data before streaming chunks back to the player.
Key features
Releases training and inference code plus pretrained checkpoints on Hugging Face and ModelScope. The design explicitly targets constant-memory long rollouts with camera revisits rather than short demo loops.
Getting started
Create the documented Python 3.10 and PyTorch CUDA environment, download the ReWorld-5B checkpoint, then run the supplied inference script and steer the camera with keyboard and mouse.
Real-time interaction
A window-split training scheme decouples precise action following from long-horizon memory, and inference pairs a bounded KV cache with a pose-indexed landmark bank so GPU memory stays constant while revisited places retrieve the right past views. The 5B model is distilled to four denoising steps and trained on metric-aligned multi-source data before streaming chunks back to the player.
Pricing
CC BY-NC-SA 4.0 code; self-hosted compute costs extra Repository code is published under CC BY-NC-SA 4.0. Confirm separate model, dataset and dependency terms before reuse. No hosted price is inferred. Budget for the documented GPU, storage and setup requirements.
Limitations
The licence is CC BY-NC-SA 4.0, which blocks commercial reuse and keeps the project out of permissive open-source groupings. Real-time streaming is a maintainer claim; the README does not publish a full latency distribution or the tested GPU tier for the released checkpoint.
EDITORIAL VIEW
Editor's Verdict
ReWorld is included as a source-available implementation relevant to real-time generative video or interactive world systems.
Run the supplied example on representative hardware and review every linked licence before production use.

Technical notes & official performance
Official Performance Data
- The README states ReWorld streams 704 × 1280 video in real time after four-step distillation. This is an author claim; Video Runtime has not benchmarked it.
Technical Notes
- Training and inference code were released in August 2026 and the checkpoints in September 2026; the paper is on arXiv (2608.23565).
