Sounds like things are moving forward on a possible Gemini-powered Siri. Mark Gurman reports on an agreement between Google and Apple for testing, and a bunch more about Apple’s plans and new Siri architecture:

Apple is rebuilding Siri around three core components: a planner, the search systems for the web and devices, and a summarizer. The planner interprets voice or text input and decides how to respond; the search system scans the web or user data; and the summarizer pulls it all together into an answer.
