bitHuman Avatar SDK

Private, real-time lip-synced avatar SDK. Runs fully on-device on any CPU (including Raspberry Pi), NVIDIA GPU, or Apple Silicon — data never leaves your hardware; self-host or deploy on-prem and air-gapped. Two models: Essence (CPU, pre-built .imx) and Expression (GPU/M3+, any face image). Python SDK (pip install bithuman), Swift SDK (SwiftPM), REST API, CLI.
