# LingBot-World 2.0

LingBot-World 2.0 extends Robbyant's world model to longer rollouts and richer interactions, in 1.3B and 14B sizes. Its weights are licensed for non-commercial use only (CC BY-NC-SA 4.0); check the license before building on a hosted version.

Organization: Robbyant (Ant Group). Released: July 2026. Kind: Explorable world.

## What you control

- A starting image
- Camera poses (4×4 pose control)
- Movement and interaction inputs

No. CC BY-NC-SA 4.0 allows non-commercial use only, and anything built from the weights must carry the same license.

## Real-time

Real-time, per authors. A distilled real-time variant drives 720p streams at 60 fps.

## How to run it
