On November 11, Google announced the official release of version 1.0 of A2UI, an open protocol for generative UI, with the official documentation now listing v1.0 as the current version. In its official blog, Google stated that this is the first stable release of the protocol, enabling AI agents to respond not only with text but also with interactive native interfaces—such as confirmation forms or charts. The blog likened the current state of user-agent interaction to the terminal era of computing: capable enough, but almost entirely text-based.
