By Matt O'Riordan, CEO and Co-Founder Across AI infrastructure right now, one word is doing a lot of work: durable. It is attached to execution. To agents. To workflows. To sessions. To streams. To transports. To memory. Every few weeks, another product ships with "durable" in the name. This is not branding noise. The underlying observation is the same in every case. AI systems are long-lived. They can fail at any layer. They need infrastructure that assumes failure rather than hopes against it.

Python dominates AI development. It's where teams build their agents, orchestration layers, and the backend systems that turn LLM calls into products people actually use. Over the past year, those systems have matured rapidly. What used to live in notebooks and prototypes is now running in production, serving real users with real expectations around reliability and performance. That maturity brings infrastructure requirements. Tokens need to stream in order.

Over the past year, I've spoken to more than 40 engineering teams building production AI agents. Different companies, different frameworks, different use cases. The same conversation kept happening.

By Amber Dawson
You start a research task on your laptop, the network drops during a meeting, and when you open your phone to continue, the conversation is gone – you re-prompt, get partial duplicate results, and lose 30 minutes of work. The delivery layer dropped it. That's one of the most consistent problems teams hit when building AI applications. It's particularly acute in customer support, where a session belongs to the conversation - not to any single device, connection, or participant.

Most teams building AI agents start with HTTP streaming. It's the right starting point. Every major agent framework defaults to it, it gets tokens on screen fast, and for a single-user prompt-response interaction it works well. The question is when it stops being enough - and how to recognise that before it turns into user experience problems, engineering waste, and technical debt that constrains what your product can do.
|
By Matthew O'Riordan
HTTP streaming – the default transport underneath every major agent framework – was never designed for sessions that survive a tab close or hand off cleanly between participants. Two failures surface consistently in production CX products because of this. Both generate support tickets about conversation state and prompt quality. Both trace to the transport layer. The scenario that illustrates them: a customer contacts support about an order that's partially shipped and partially stuck.

Every major layer of the AI stack now has a name. Model providers - OpenAI, Anthropic, Google - handle inference. Agent frameworks - Vercel AI SDK, LangGraph, CrewAI - handle orchestration. Durable execution platforms like Temporal make backend workflows crash-proof.

There’s no shortage of noise in AI right now. New frameworks, protocols, demos, and acronyms appear almost weekly. But when you speak directly to the teams actually shipping AI to users at scale, a different picture emerges. This is what we've learned over the last few months from speaking to CTOs, AI engineering leads, and product leaders from unicorns, public companies, and fast-growing platforms across industries where humans interact directly with AI.

Shared state is a hard problem. Not hard in the abstract, computer-science sense (the concepts are well understood). Hard in the someone has to actually build this sense, where every team that wants a live leaderboard, a shared config panel, or a poll that updates in real time ends up reinventing the same wheels: conflict resolution, reconnection handling, state recovery. Most teams do not want to spend their time building and maintaining that layer. They want to ship the feature that depends on it.
|
By Amber Dawson
Most AI applications start the same way: wire up an LLM, stream tokens to the browser, ship. That works for simple request-response. It breaks when sessions outlast a connection, when users switch devices, or when an agent needs to hand off to a human. The cracks appear in the delivery layer, not the model. Every serious production team discovers this independently and builds their own workaround. Those workarounds don't hold once users start hitting them in production.

How do you deliver token streams, sync conversation state across devices, and let users interrupt an agent mid-response -- without rebuilding your stack every time you switch frameworks? Mike Christensen demonstrates Ably AI Transport in action, walking through the key primitives every production AI application needs and showcasing a multi-agent holiday planning app built on those primitives. Topics covered.

React Server Components (RSCs) seem to be everywhere lately, but what problem do they really solve? In this video, Alex Booker from Ably (@CodeCast) explores RSCs from scratch, revealing the motivation and benefits behind them. You might be surprised to learn - they're not merely a React feature, but a fundamentally new model for building full-stack React applications with meta frameworks like Next 13.4 by Vercel.

Tom Camp, DevRel Engineer at Ably takes you through a tutorial of adding an avatar stack to your application using Ably's latest product, Spaces. An avatar stack is a visual representation of a user’s presence - showing them as online and connected. They are the most common way of showing the online status of members in an application by displaying an avatar for each member. Events are emitted whenever a member enters or leaves a space, or updates their profile data.

In this WebSocket tutorial, Alex Booker from Ably (@CodeCast) teaches you how to implement realtime updates in your React applications. Here, we use React on the frontend and Node on the back to build a live cursors feature from scratch, but the fundamental WebSocket lessons can be applied to any manner of realtime application. WebSockets are a bidirectional full-duplex communication protocol used to enable realtime updates such as chat, multiplayer collaboration, notifications, and other live updates in your React applications.

Online gamers have the most demanding realtime expectations. Mobile gaming now the largest sector of app store purchases, accounting for 42% of a $109 billion marketplace. It's vital that game developers offer a level of mobile performance that delivers an optimum realtime experience for every user. This white paper highlights some of the UX issues that can undermine your company's ability to do this effectively.

I watch sports for a living. I couldn't tell you the last time I watched a baseball game from beginning to end. Data is one of the most valuable resources around. But data is no longer something that languishes in a database to be looked at later. Like sports events, data is now live. The sports industry can reap and build on innovations in the realtime data space. But this is no long a nice-to-have. Driven by changing fan behaviour this is now a commercial imperative.

Sports and gaming app users demand an uninterrupted, true realtime experience. Almost 90% of US adults now use a mobile device while watching sports. In competitive arenas with similar offerings, like betting or sports, then you absolutely cannot afford to deliver poor mobile experiences. Customer experience is the new competitive battleground and realtime mobile experiences are an essential part of that.
