Agentic apps that go beyond chat

What this post added

This post details the integration of Ably AI Transport with the Vercel AI SDK to build collaborative AI applications. It showcases how Ably's durable sessions, LiveObjects, and Presence provide a unified layer for handling real-time events, shared state (itinerary, budget), and collaborator awareness, eliminating the need for separate stream stores, sync layers, or presence services. Key technical aspects include using Ably's custom transport for `useChat`, server-side streaming of model output to Ably channels, conflict-free updates via LiveObjects, and presence management for multi-user visibility.
