Building applications for the web has evolved over the years. With new technologies and frameworks promising different things, browsers have also gotten smarter. Across board, we still prioritize creating a fast, seamless and accessible experience for users. This talk will be focused on simplifying some of the steps we can start practicing, to optimize for performance in web applications.

Performant Architecture for a Fast Gen AI User Experience

More and more developers are being asked to build Generative AI experiences into their web applications everywhere. However, the user's experience with Generative AI can sometimes be slow and frustrating. It’s been years since we would gladly wait over 10 seconds for a response to anything online. As AI processing gets faster, there are new limiting factors that could be negatively affecting your AI user experience.

In this talk, we will cover different ways to minimise laggy experiences in web applications when interacting with third-party Generative AI tools. We’ll be using a practical demonstration to show how you can reduce latency as we build one of my favourite sci fi gadgets, the babel fish.

Performance optimization is critical to delivering fast and seamless user experiences in the ever-evolving web development landscape. This talk delves into the innovative use of speculation rules to enhance web loading times and overall performance. Attendees will gain insights into the principles and mechanisms behind speculation rules, learn how they predict and pre-fetch resources, and explore real-world applications and case studies demonstrating their impact.
