Call for Participation in Generative UI Community Group

The Generative UI Community Group has been launched:

Background

Recent progress in large language models and agent-based systems has enabled Generative UI, in which user interfaces are synthesized at runtime based on intent, context, and user needs rather than being pre-authored. As noted in the Web & AI Interest Group(Issue #3), this evolution raises new questions for the Web around interoperability, performance, accessibility, and alignment with existing concepts of the Web platform, motivating exploratory work within W3C to scope and better understand the associated design space.

Scope

The Generative UI Community Group will conduct exploratory work in the following areas:

• Evaluation and performance: Explore how latency, responsiveness, and output quality of Generative UI can be characterized and assessed in Web-based environments, and identify potential gaps in existing W3C work.
• Validation and testing: Study validation and testing approaches for Generative UI that go beyond traditional end-to-end testing, including the use of structured test cases and reference implementations.
• Intermediate representations: Investigate the potential value of lightweight, cross-vendor intermediate representations or protocols for Generative UI to improve interoperability and model compatibility.
• Alignment with the Web platform: Examine whether Generative UI systems benefit from a constrained or lightweight subset of Web technologies aligned with existing Web principles.

This group may publish Specifications.

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2026-01-29 by Ruoxi Ran. The following people supported its creation: Raphaël Troncy, Chunming Hu, Xiaoqian Wu, Ruoxi Ran and Hai Rao. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group on social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at site-comments@w3.org

Thank you,
W3C Community Development Team
