Overview

Agents Streams V2 is the streaming layer for Expressive Agents. It is built on LiveKit.

Note: V2 works only with Expressive Agents. Other agent types continue to use Agents Streams V1.

How It Works

flowchart LR
    App(["fa:fa-laptop Your App"]) --> Session(["fa:fa-key Session Credentials"])
    Session --> LiveKit(["fa:fa-signal LiveKit Room"])
    LiveKit -- "speak / chat" --> Agent(["fa:fa-circle-user Expressive Agent"])
    Agent -- "video + events" --> LiveKit
    LiveKit --> App

After you create a session, your app connects to a LiveKit room using the returned URL and token. All commands (speak, chat) and responses (video events, partial answers) flow through the LiveKit data channel — no separate HTTP calls once connected.
