Run on your GPU

On Linux or WSL2 with an NVIDIA GPU:

curl -fsSL https://raw.githubusercontent.com/openspline/openspline/main/install.sh | sh
sh ~/.local/share/openspline/run.sh

Open http://localhost:7860 for the demo. Then use the same service from your agent:

pip install openspline

from openspline import Openspline

async with Openspline().avatar("portrait.jpg", quality="low") as avatar:
    print(avatar.viewer_url)
    await avatar.stream(agent.audio_stream(), sample_rate=24000)

Open the printed viewer URL. The default service URL is http://localhost:7860. PyTorch uses CUDA 12.8 for Blackwell and CUDA 12.6 for older NVIDIA GPUs. AMD and Apple GPUs are unsupported. See GPU workers for multiple GPUs and High quality.
