In the rapidly evolving world of artificial intelligence, the user experience (UX) of AI-powered applications is often a point of friction. Mike Christensen, a staff engineer at Ably, delivered a compelling presentation at AI Engineer Europe titled “Why Your AI UX Is Broken (and It’s Not the Model’s Fault).” Christensen argued that the common perception of AI UX issues stemming from flawed models is often a misdiagnosis, with the real culprits lying in the fundamental architecture and implementation of these systems.

AI UX is Broken, Not the Model — from AI Engineer

Visual TL;DR. AI UX is Broken is Not Model Fault. Not Model Fault due to Default Architecture. Default Architecture has HTTP Streaming Problems. HTTP Streaming Problems solved by Decoupling & Durable Sessions. Decoupling & Durable Sessions example Ably’s AI Transport. Decoupling & Durable Sessions enables Improved AI UX.

1. AI UX is Broken: user experience issues in AI applications are common and frustrating
2. Not Model Fault: problems stem from infrastructure, not the AI models themselves
3. Default Architecture: common pattern uses HTTP streaming for AI chat applications
4. HTTP Streaming Problems: single point-to-point connection creates issues with AI event streams
5. Decoupling & Durable Sessions: solution involves separating components and maintaining persistent connections
6. Ably’s AI Transport: real-world implementation of the proposed durable session architecture
7. Improved AI UX: fixing infrastructure leads to better user experiences with AI
