Real-time avatars that run completely locally, off the internet.

What it is

Plans: Business & Enterprise.
Billing: credit-based, from 100,000 credits, metered on the machine.
Connectivity: no required reconnection.
Pack: prepaid offline credit, bound to one machine.

Buy a pack in the console (how), or contact sales for Enterprise terms.

Fully offline. Offline license is only available to Business and Enterprise clients who want to run realtime avatars completely locally, off the internet — e.g. kiosks, trade shows, ATM machines, embedded screens. Linux and macOS computers (Apple silicon); bought in the console or through sales. The avatar renders on the machine and usage is metered there, with no required reconnection. Models: Essence 2, Expression 2 and Essence 1 now.

Creating the avatar from a portrait happens in the bitHuman cloud; the finished avatar model then runs on your machines.

Speed

An offline machine is a Linux PC or a Mac with Apple silicon. How fast each model renders on a Linux PC with no GPU is on CPU only (no GPU).

Price

From 100,000 credits, credit-based and metered on the machine. Business & Enterprise; bought in the console or through sales.

Limits

Essence 1 runs fully offline today on Linux (x86_64 and ARM64) and on macOS with Apple silicon. Essence 2 and Expression 2 run fully offline on Linux x86_64 (bitHuman 2.11.17 or later). On Linux, the Python package and the bitHuman CLI (2.8.4 or later) both run offline packs; on a Mac, the Python package. Expression 1 runs in the bitHuman cloud only.

Phones and browsers stay online: the Swift package, the Android SDK and the web embed check your credential when a session starts.
Creation is online: you create the avatar from a portrait in the bitHuman cloud before it runs offline.
One model per process: a pack meters everything its process renders, so run each model (Essence 1, Essence 2, Expression 2) in its own process.
File rendering: without a pack, bithuman render and Python’s render() sign in online and bill your account. With an installed pack that covers the avatar, they render with no network and no API secret, and spend the pack.

First command

Buy a pack for the offline license in the console (Developer → Offline licenses), choosing the model and the platform it will run on. A pack is at least 100,000 credits at the self-hosted rate. You can cancel it for a full refund until a machine redeems it. Through the API: POST /v1/offline/entitlements with "platform": "linux-x86_64", "linux-aarch64" or "macos-arm64".
Redeem it once, on the machine that will run it, while it is online, with your account’s API secret and bitHuman 2.11.16 or later on Linux (2.11.17 or later on a Mac):
```
pip install -U "bithuman>=2.11.17"
export BITHUMAN_API_SECRET=...
python -m bithuman pack redeem
```
For Expression 2, install "bithuman[expression-2]>=2.11.17" instead. With the bitHuman CLI on Linux (2.8.4 or later), bithuman pack redeem with BITHUMAN_API_SECRET set does the same.

This binds the pack to this machine and installs it; on a Mac it is sealed with the Mac’s Secure Enclave. If the install step fails, python -m bithuman pack redeem --file <pack> retries it from the copy kept in ~/.bithuman/packs/, with no connection and no second charge.
Prepare the machine once while online. Render your avatar once before you disconnect (python -m bithuman render <avatar> <audio>), or with the CLI run bithuman pull <avatar>. This downloads the avatar and the engine files its model needs; a render is metered by the pack like any other.
Run offline. The machine now renders with no network and no API secret until the pack’s credits are spent. Credits are metered on the machine, at the self-hosted rate for active session time. It never has to reconnect.
