Reactor LingBot-World-2
LingBot-World-2 is Reactor's newest real-time world model and the successor to the open-source LingBot-World. Built on Wan2.2, it generates diverse, high-fidelity environments — from photoreal to scientific and cartoon styles — and stays interactive at 16 fps with sub-1-second latency, holding minute-scale horizons with long-term contextual consistency.
Overview
| Status | Live in Roamscape |
|---|---|
| Access | Runnable in Roamscape |
| Released | 2026 |
| Inputs | reference image, text prompt, control signals (camera / action) |
| Outputs | real-time navigable video stream (1664×960 @ 48 fps) |
| Best for | minute-scale live worlds, camera + action controlled exploration, high-fidelity real-time worlds, content creation & gaming, robot-learning simulation |
Why it matters
It narrows the gap between open and closed real-time world models, with explicit camera-pose and action control that makes live exploration feel genuinely navigable — a strong fit for content creation, gaming and robot-learning.
Roamscape use
Live in Roamscape as a paid real-time navigable world model session at /live.
Strengths
- 48 fps, 1664×960, sub-second latency
- two-axis WASD movement + directed camera poses
- live prompt hot-swap mid-stream (no restart)
- diverse styles, realism to cartoon
- built on Wan2.2, typed SDK available
Limitations
- live stream rather than an exportable 3D asset
- bills per GPU session-second (~$11.88/hour)
- needs a reference image + prompt to anchor
- commands apply at the next chunk boundary
