FAQs

How is avatar quality so high at a low price?
Protoface uses newer, more efficient models instead of the lower-quality Gaussian-style models most cheap avatar APIs rely on. Until now, low-cost real-time avatars usually meant sacrificing realism. Protoface makes premium-quality avatars available at the same price point.
