OpenUI 1.0: Giving Agents an Interface, Not a Paragraph
Thesys's 90-second launch film for OpenUI 1.0, an open-source (MIT) generative-UI framework that lets AI agents respond with live, interactive interfaces instead of text. Built on a compact streaming-first language (OpenUI Lang, ~67% fewer tokens than JSON) with runtimes for React, Vue, Svelte and Angular. The core design stance: you choose the components, the model decides what the user needs, OpenUI renders it — not freestyle. Notes the naming collision with Weights & Biases' wandb/openui, and flags the '6M downloads' figure as a vendor claim.
