Designing Fast, Delightful UX With LLMs for Mobile Frontends

Tuesday Nov 18 / 02:45PM PST, Pacific DEKJ at Hyatt Regency, San Francisco

Abstract

Delivering AI-powered features in mobile apps is not just about calling an LLM API. It is about crafting fast, reliable, and engaging user experiences. In this talk, I’ll share practical lessons from designing and scaling LLM-driven experiences in mobile apps, where frontend architecture and UX design played an important role.

We’ll explore how to architect for speed and interactivity, when to use on-device LLMs versus backend inference, and how to design interfaces that gracefully handle latency. We'll also examine the trade-offs that shape responsive, cost-effective, and scalable AI features.

Whether you're experimenting with LLMs in your product or already in production, you’ll leave with insights to make your AI-powered experiences feel fast, native, and user-first.
