Real-Time Presence
Entanglement
She responds the instant you stop — live, and many at once.
Responsiveness is what people actually feel. Entanglement holds the avatar's expression, timing, and attention as a single correlated state with the live conversation — she and the person she's speaking with move as one. She knows the exact instant a thought is finished and answers in real time, and she does so live, at scale, with many conversations held coherent simultaneously.
Just as two entangled particles share one state across distance, the avatar and the visitor are bound into a single, unbroken, real-time exchange. This is the pillar that turns a sequence of models into a conversation.
The technology
A low-latency turn-taking model predicts end-of-utterance from fused acoustic and visual cues through a probability-scaled decision ladder, while a real-time synchronization layer keeps the rendered avatar in lockstep with the live exchange. A resource governor schedules many concurrent sessions on shared hardware, adapting render fidelity under load so responsiveness never degrades.
Why it matters
A perfect face that answers a beat too late is not present. Entanglement is the faculty of now — it is what lets a digital human hold a real conversation instead of taking turns with one.
