The only production API delivering genuinely real-time interactive generative video — MirageLSD transforms live streams frame-by-frame at ~25fps with sub-100ms latency and unlimited duration, and the Oasis line demonstrated fully playable model-generated worlds; near-tie with Sora 2 on this list, ranked below it only because Decart's fidelity and generality are narrower.
Where Decart falls short, per the models
- Claude Focused on real-time style transformation and game-like demos at modest resolution — it won't generate arbitrary high-fidelity environments or exportable 3D geometry.
