HeyGen has just unveiled the Avatar IV API, their most advanced image-to-video avatar technology yet. This update makes it easier than ever for developers and product teams to bring realistic talking avatars into their apps, platforms, and services.
With just a single photo and a script, the Avatar IV API can generate studio-quality avatar videos featuring clean lip-sync, natural facial expressions, and even hand gestures—all without cameras, actors, or production crews.

The result is video content that feels authentic, engaging, and emotionally connected.
