Amazon makes AI chatbots respond faster with smart request routing
Amazon has released a new feature that speeds up how quickly AI language models answer your questions. By sending similar requests to the same computer, the system can reuse previous work and cut response times by more than half.
When you chat with an AI chatbot, there's usually a small delay before it starts typing its reply. Amazon just announced a way to cut that delay significantly using a technique called "prefix-aware routing."
Here's how it works in plain terms: imagine you're asking multiple questions that all start the same way — for example, "Tell me about the history of..." followed by different topics. Instead of treating each question separately, the new system recognizes this shared beginning and sends all these requests to the same computer. This lets the AI reuse information it already prepared, rather than starting from scratch each time.
In tests on a large AI model, this approach reduced the wait time for the first response by up to 77%. That's a huge improvement. For everyday users, this means chatbots and AI assistants will feel more responsive — less like they're thinking, more like they're already prepared to answer.
The feature is now available through Amazon SageMaker Inference, which is the platform Amazon provides for companies running AI models. It's particularly useful for scenarios where many people ask similar questions or where the same context is used repeatedly.
