I tested it immediately, but it is disappointing. At least here in Switzerland, it is not able to generate images, and a simple "look up this website and summarise the content" does not work either (can't access the website, but its a public website without any crawling limitations). I don't understand why Google is launching a product like this.
It's confusing because the name Bard and the UI also got an upgrade today, so I thought I was using Gemini Ultra but it turns out I'm not: https://imgur.com/a/3UriYpn — showing that Gemini Advanced is not what I'm using, unless I pay and upgrade. (If you cannot generate images you're likely not using Gemini Advanced.)
I have different levels of access to Bard through different accounts, and the feature set varies wildly. Generating images and summarizing websites is enabled in _some_ configurations, but I have no idea what the rules are.
The feature set also seems to depend on other factors: The account that is images-enabled only does so if I ask in English, but not when asking in any other language I tried.
