bitHuman cloud

bitHuman renders the avatar on its servers and streams it to you.

What it is

The fewest moving parts: bitHuman renders the avatar in the cloud and streams its video and audio to a web page, an app or a LiveKit room. You provision no GPU and install nothing.

Where it renders

Question	bitHuman cloud
Where the avatar renders	on bitHuman's servers, in the US
Where the conversation runs	on bitHuman's voice service, or with your own provider keys
What reaches bitHuman	the session's audio and conversation, to run it
Network	required for the whole session

bitHuman cloud. In the bitHuman cloud the avatar renders on bitHuman's servers, in the US, and the conversation runs on bitHuman's voice service or with the provider keys you connect. The browser or app sends the microphone and shows the video. Your API secret stays on your server; browsers get scoped embed tokens.

A managed agent’s conversation runs on bitHuman’s voice service with your persona, or with the voice and language providers whose keys you connect (Voices, Providers). Traffic is encrypted in transit: HTTPS, and WebRTC media over DTLS-SRTP.

Speed

bitHuman picks the server for each session, and every server type renders faster than real time:

Configuration	Essence 2	Expression 2
NVIDIA RTX 4090 Cloud API · GPU	4.1× real time NVIDIA RTX 4090 · cloud API · measured 2026-09-27	17.0× real time NVIDIA RTX 4090 · cloud API · measured 2026-09-23
Apple M4 Max Cloud API · Apple silicon	2.8× real time Apple M4 Max · cloud API · measured 2026-09-26	5.5× real time Apple M4 Max · cloud API · measured 2026-09-23
x86 server CPU Cloud API · CPU CPU only (no GPU)	1.1× real time x86 server CPU, CPU only (no GPU) · cloud API · measured 2026-09-25	1.3× real time x86 server CPU, CPU only (no GPU) · cloud API · measured 2026-09-24

Times real time: seconds of avatar video rendered per second. At 1.0× or more, an avatar holds a live conversation. Select a figure for its release and date. All configurations and how we measure.

Price

4 credits per minute of active session time for Essence 2 and Expression 2, about $0.04 a minute at the top-up rate of $1 = 100 credits. A managed agent's voice chat bills 10 credits per minute, all-inclusive: the avatar is part of it. Real-time usage bills active session time, talking or idle, to the second. Every rate: Pricing and credits.

Limits

bitHuman cloud sessions are limited per plan: Creator 3, Pro 10, Business 50, Enterprise 200 concurrent sessions. On-device and self-hosted sessions are limited by credits (plans).

A session over your plan’s limit is refused with 403 CONCURRENCY_LIMIT_REACHED (Rate limits). The network is needed for the whole session.

First command

Web embed

<iframe src="https://www.bithuman.ai/embed/A23WJF0199" allow="microphone *"
        style="width:100%;height:600px;border:0"></iframe>

REST API

curl -s -X POST https://api.bithuman.ai/v1/video/generate \
  -H "api-secret: $BITHUMAN_API_SECRET" -H "Content-Type: application/json" \
  -d '{"model": "expression-2", "agent_code": "A23WJF0199", "input": {"type": "audio", "audio_url": "https://docs.bithuman.ai/samples/speech-16k-short.wav"}}'
# → {"success": true, "job_id": "vid_…", "status": "processing"}; poll GET /v1/video/{job_id} for video_url

LiveKit

pip install "livekit-agents[openai,silero]" livekit-plugins-bithuman python-dotenv
# then pass avatar_id= to bithuman.AvatarSession: /platforms/livekit

Next steps: Web, REST API, LiveKit, or a cloud avatar in your own room without the plugin.
