What you can build

• Real-time avatars — Audio in, lip-synced animated face out at 25 FPS.
• Talking avatar videos — Generate scripted videos with any face image.
• Illustrated multimedia books — Combine characters, narration, and imagery.
• Shareable multi-avatar apps — Embed bitHuman agents anywhere.

Runs everywhere

Python SDK (pip install bithuman), Swift SDK for Apple devices, REST API, and a no-code web dashboard. Essence model runs on any CPU. Expression model runs on NVIDIA GPU or Apple Silicon M3+. All inference is on-device — the only network call is a 1-request-per-minute billing heartbeat.

Private, on-prem, and cost-effective

Because every avatar renders on-device, your audio, video, and prompts never leave your hardware — private by design, with no cloud round-trip. Deploy self-hosted, on-premise, or fully air-gapped for regulated, offline, and privacy-sensitive environments. And because there is no per-request cloud inference, bitHuman is the most cost-effective real-time avatar platform — from 1 credit per minute self-hosted.
