What bitHuman is today

• Real-time talking avatars from one portrait. Essence 2 renders a photoreal person; Expression 2 renders any character (people, animals, cartoons).
• Renders on the device: iPhone, iPad and Mac (Swift package), Android arm64 (Android SDK), macOS and Linux (CLI, Python), Windows 11 x86_64 (Python), and in a browser tab with WebGPU. Both models also run live on a standard Linux PC with no GPU. Or use the bitHuman cloud (REST API, web embed, LiveKit).

• API and SDK use requires the Creator plan or higher.
