A realtime avatar model that can animate a person, illustration, or nonhuman character from one image and connect to an existing voice-agent stack.
Treat the provider's avatar latency as one part of the conversation loop. Confirm output resolution, concurrency, minute accounting, regional processing, and contractual zero-retention before committing.
Anam's expressive realtime digital-person model for live conversations with image-based avatars, emotion direction, and bring-your-own AI components.
Default recording and enterprise zero-retention are different configurations. Confirm consent, biometric handling, storage duration, concurrency, and the full end-to-end latency before exposing an avatar to customers.
