GOOGLE APPEARS TO BE WORKING ON AN ‘ADVANCED’ VERSION OF BARD THAT YOU HAVE TO PAY FOR

Summary from the TLDR newsletter

Bard Advanced is an upgraded version of Bard that may soon be available through a paid subscription to Google One. It appears to be powered by Gemini Ultra, an upgrade over the current version of Bard which runs the mid-tier Gemini Pro. There may be a feature that allows users to create custom bots, but it is unclear whether users will be able to share these bots. It is unknown when or if the feature will become official.
