Your Vercel AI SDK app is missing a session layer

The integration of Ably AI Transport with Vercel's AI SDK enhances the useChat feature by introducing advanced capabilities such as resumable streams, cross-device and multi-user synchronization, conversation branching, history compaction, and stop-and-approve controls. By swapping the default transport of useChat for Ably AI Transport, conversations can now be resumed after interruptions, synchronized across multiple devices and users, and managed with branching and compaction features that streamline the stored conversation history. This setup allows for a collaborative environment where multiple users can engage in a shared session and see the full conversation history, with the ability to approve or stop actions before they are executed. The demo illustrates these capabilities, showing how the new transport maintains session durability and enhances the chat experience without altering the Next.js app's model, tools, or message components.
