summary

Company launches beta with over 300 customers using personas built from WebRTC → VAD → transcription → LLM → TTS → animation → renderer, claiming full‑pixel generation rather than lip‑dub. Engineering reports 744 ms average latency versus an 800 millisecond northstar and over 1,000 failed experiments tracked while targeting subsecond responsiveness. Demo attempts include a live browser embed that stumbles on audio and HTML errors, and a oneshot persona feature that hallucinates missing facial detail to produce smooth real‑time video.
