Open-source library treats AI as a real-time UI participant, not just a backend service

The performative-ui library, published on GitHub by Nathaniel J. Smith (known for Python async infrastructure), ships with interactive component demos and a full catalog. It explores UI architectures where AI models actively shape interface behaviour and appearance at runtime, departing from the current mainstream pattern of bolting AI outputs onto static front-ends. The research-stage project signals an unsolved design problem worth hands-on investigation by frontend engineers building at the LLM-UI intersection.
