Ably AI Transport is now available

The key shift: sessions become channels

In a connection-oriented setup, the “session” effectively lives inside the streaming pipe. When the pipe breaks, continuity becomes a headache.

With AI Transport, the session is created once and represented as a durable channel. Agents and clients can join independently. Refresh becomes reattach and hydrate. Device switching becomes another subscriber joining the same session. Multi-device behaviour becomes fan-out rather than custom routing. Agents and humans become truly connected over a transport designed for AI bi-directional low latency conversations.

Concrete examples

Multi-device copilots: A user starts a long-running answer on desktop, switches to mobile mid-response, and the session continues without restarting. Steering and approvals apply to the same session regardless of device.

Getting started (low friction)

You can get a basic session running in minutes:

js

import Ably from 'ably';



// Initialize Ably Realtime client

const realtime = new Ably.Realtime({ key: 'API_KEY' });



// Create a channel for publishing streamed AI responses

const channel = realtime.channels.get('my-channel');



// Publish initial message and capture the serial for appending tokens

const { serials: [msgSerial] } = await channel.publish('response', { data: '' });



// Example: stream returns events like { type: 'token', text: 'Hello' }

for await (const event of stream) {

  // Append each token as it arrives

  if (event.type === 'token') {

    channel.appendMessage(msgSerial, event.text);

  }

}
