# About AI Transport

AI Transport is a drop-in durable session layer for AI applications. Conversations survive disconnects, span devices, and let any client signal any agent through the same session.

AI Transport gives your AI agents a session that outlives the connection. Tokens stream over a session, not a single HTTP request, so a client reconnects without losing the response. The same session is open to any device the user picks up. Any participant publishes to the session, so a stop button on the phone cancels a turn that started on the laptop.

It works with any AI model or framework: OpenAI, Anthropic, Vercel AI SDK, LangChain, or your own stack. AI Transport runs on Ably's [fault-tolerant](https://ably.com/docs/platform/architecture/fault-tolerance.md?source=llms.txt) global platform, with messaging at [low latency](https://ably.com/docs/platform/architecture/latency.md?source=llms.txt) across regions and [elastic scale](https://ably.com/docs/platform/architecture/platform-scalability.md?source=llms.txt).
