This talk introduces three architectural patterns for bridging that gap: (1) a versioned rendering contract that tells the model which UI components are available on the client, so it picks from a fixed menu rather than inventing new ones; (2) streaming typed UI components instead of raw text, shifting the key metric from total latency to time-to-first-chunk; and (3) a Backend-for-Frontend (BFF) layer that hydrates model output into platform-specific, action-aware UI elements, keeping the client 'dumb and safe.' The approach is especially important for mobile apps where client patches are impractical and crashes persist across unupdated installs. The concept now has a name — Generative UI — and an open spec (A2UI from Google), making it easier for teams to build on shared vocabulary rather than solving the problem from scratch each time. ## Full article daily.dev links to this article rather than hosting it.
