As software turns probabilistic, interfaces shift from defining features to narrowing possibilities
round · x · 2026-10-22
A forwarded observation on how AI changes software design:
- Classic deterministic software exposed a fixed set of interface states that signaled capability — the interface was the feature set
- With probabilistic software, capability is latent in models, no longer enumerated by the UI
- The interface's new role is to impose state on top, deliberately narrowing open-ended possibility into legible, dependable interaction
A crisp framing of the AI product design shift: the craft moves from implementing features to constraining latent model capability.
