Facts checked September 4, 2026
Quick take
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.
Hedra's audio-driven character model for creating talking videos from one image, one to four speakers, and optional performance direction.
Credit units are not dollars, and a ten-minute 1080p render can consume substantial capacity. Verify generation time, moderation, identity consent, storage, and the credit package behind the account.
