01 / THE DEVELOPER EXPERIENCE

A face in
5 lines of code.

Keep your models, prompts, and tools.
Send audio. Get synchronized video.
That’s the whole idea.

Read the quickstart

First, start the GPU service.
Then connect your existing agent.

$ pip install openspline

from openspline import Openspline

client = Openspline()

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

02 / PLUG INTO YOUR STACK

Integrate with your existing voice AI

Keep your voice, tools, and prompts.
Add an avatar where your audio already flows.

$ pip install openspline 'livekit-agents[openai]==1.8.3'

from openspline import Openspline
from openspline.integrations.livekit import AvatarSession

avatar = AvatarSession(
    "portrait.jpg", client=Openspline(quality="low")
)
await avatar.start(agent_session, room=ctx.room)
await agent_session.start(room=ctx.room, agent=agent)

# Your LiveKit room carries the synchronized audio and video.

03 / Use Cases

Make your agents more human.

For the moments when a voice
could use a face.

Tutors that connect.

Build a language partner, a patient teacher, or a guide for that first day.

LEARNING & TRAINING

Characters with character.

Give your game NPCs, digital companions, and interactive stories a voice and a face.

GAMES & COMPANIONS

A friendlier front door.

Put a face to your support agent, product guide, or welcome-screen assistant.
