Ably AI Transport is now in early access. It gives your AI the continuity, awareness, and multi-device reliability users actually expect. Drop it in, keep your existing stack, and start shipping Gen-2 AI right away.
The AI Transport that you need…but won’t build
Models have leapt forward, but the infrastructure around them hasn’t. LLMs can reason, retrieve, plan, and coordinate - yet most apps still deliver them through short-lived, one-way HTTP requests.
This mismatch is now the bottleneck.
Teams building AI assistants want them to stay aware, survive interruptions, understand device changes, stay in sync, but the underlying transport simply wasn’t designed for long-lived, stateful AI.
GEN 1 AI UX | GEN 2 AI UX | |
INTERACTION MODEL | Single prompt → answer | Continuous conversation with streaming |
CONTINUITY | Tab-scoped session | Resumable across devices/sessions |
PROGRESS VISIBILITY | Limited / none | Live tokens, steps, ETA, thinking communicated |
CONTROL | Restart | Barge-in, redirect, pause/resume |
BACKGROUND WORK | Not supported | Runs after you leave (decoupled from app/browser session), notifies on completion |
COLLABORATION | Limited advisor | Agent assistant and multi-user |
NOTIFICATIONS | Inline with request | Push updates (in-app, mobile, live activity panel) |
The problem, AI that breaks the experience
When real users show up, the cracks appear immediately. A tab reloads and the thread disappears. A network drops and the stream resets. Two agents respond at once and confuse the user. A human joins the conversation with no shared context. Switching devices means starting over.
Teams try to patch this together with HTTP streams, polling, and custom glue code - tools never meant for long-running, multi-party, stateful AI. It slows delivery, introduces fragility, and makes shipping reliable agentic AI harder than it should be.
The solution, a realtime foundation built for AI
Ably AI Transport closes that gap. It’s the realtime foundation that sits beneath any model or agent framework and gives you continuity, control, and shared state without replacing your stack.
Under the hood is a global WebSocket platform, the same platform that already powers billions of messages each day. It keeps conversations, state, and agents in sync at all times. Streams stay alive through reloads, state hydrates instantly when a user returns, and multiple agents can collaborate in the same shared context. Tool calls arrive exactly when an agent needs them, and a human can step into the same thread with full visibility rather than starting cold.
“Ably gives us the reliable, low-latency AI transport we need for Messenger and Fin. No polling, no dropped messages, just a platform we can finally build next-generation AI experiences on.” Colin Kennedy, Principal Product Engineer, Intercom
You do not have to change how you call your model. Ably AI Transport is the realtime layer that carries state and continuity between your AI, your users, and your agents. It works with any LLM or framework, and it evolves with your stack as you adopt new models or agent runtimes. The transport remains stable, even as everything above it changes.
“Everyone wants AI that feels intelligent, but almost no one wants to build the infrastructure that makes that possible,” said Matt O’Riordan, CEO of Ably. “Models are improving fast, but the experience around them still breaks in basic ways. Ably AI Transport gives teams the missing layer that makes AI feel continuous and reliable, without forcing them to rebuild their whole stack.”
