WebSockets, standardized as RFC 6455 in 2011, structurally outperform Server-Sent Events (SSE) for AI streaming because SSE carries data one way from server to client and cannot deliver mid-stream can…
Ably, a realtime messaging platform, argues that raw WebSockets leave AI streaming developers to build and maintain four pieces of infrastructure—reconnection, cancellation, multi-device delivery, and…

McKinsey's 2025 State of AI survey finds only 39% of organizations report any EBIT impact from AI, despite 88% using AI in at least one business function. The article argues that measuring AI adoption…
Vercel AI SDK's useChat hook lacks a session layer for multi-device sync, multi-user conversations, and resumable streams. Ably AI Transport replaces the default transport to add these features, enabl…
Developers using the Vercel AI SDK are discovering that calling chat.stop() only closes the client connection, not the server-side generation, leading to continued billing. Fixing this requires a dedi…
Ably and Vercel released Wayfarer, an open-source demo of a collaborative AI travel-planning app that uses a durable session to synchronize real-time agent streams, shared state, and multi-user presen…
Ably released AI Transport v0.3.0, adding first-class support for presence and LiveObjects to AI sessions, enabling real-time visibility of online participants and synchronized shared state. The updat…
