## Summary

Thesys has released OpenUI 1.0, an open-source framework that lets agents create working interfaces inside apps. On its own benchmark of 46 interface briefs across six models, OpenUI used 58% fewer output tokens than Vercel's json-render and 52% fewer than Google's A2UI.

## Why it matters

The source gives concrete token savings against two named alternatives on a stated benchmark, which helps readers compare agent UI frameworks on cost.

> OpenUI allows models to write a compact UI language that renders on screen while the answer is still being generated.

> It works with any model, including open-weight ones running on a team's own hardware.

> Version 1.0 adds custom actions, allowing buttons inside a generated answer to activate an app's own code.
