Thesys releases OpenUI 1.0, an open-source UI framework
Summary
Thesys has announced the release of OpenUI 1.0, an open-source framework that enables developers to create dynamic user interfaces within applications. This new version introduces custom actions that allow buttons in generated responses to trigger an app's own code, working seamlessly with various web frameworks, including React, Vue, and Angular. In comparative benchmarks, OpenUI demonstrated significant efficiency, using 58% fewer output tokens than Vercel's json-render and 52% fewer than Google's A2UI. The framework is designed to be compatible with both open and closed model providers such as OpenAI and Anthropic, enhancing its versatility for developers across different environments.
