Today, a developer who wants a lifelike, real-time avatar in their product has to stitch together a streaming pipeline, a rendering layer, an agent, and a set of hard real-time problems - latency, interruption handling, listening behavior, expressiveness, consistency across sessions, most of which have nothing to do with the product they're actually trying to build. Interactive Avatars is in closed beta today, and the teams building on it are pushing it into places we didn't expect - AI sales reps, always-on support agents, interactive trainers, onboarding guides.
