AI-powered features are rapidly becoming a standard expectation in modern applications but integrating them into frontend experiences introduces a new class of engineering and UX challenges. From increased latency and streaming complexity to unpredictable responses and overloaded interfaces, many “smart” features quietly make applications feel slower and less enjoyable to use.

In this talk, we’ll explore the real-world lessons learned from shipping AI-powered frontend experiences in production. We’ll examine the hidden trade-offs behind AI integrations, why responsiveness often matters more than intelligence, and how frontend architecture must evolve to support probabilistic, long-running interactions.

The session will cover practical strategies for handling streaming responses, managing UI state, reducing perceived latency, structuring frontend/backend responsibilities, and building resilient user experiences around AI systems.

Attendees will leave with a clearer understanding of how to design AI-powered applications that feel fast, responsive, and reliable without sacrificing user experience in the process.
