It either came installed on my S24 or was part of the recent UI update. I got my S24 a month ago and I thought it asked me when I got it if I wanted to switch to Gemini. It asked me again the other day after using Google assistant to set a timer for me and I ended up switching to Gemini. I have not looked into the features yet. I see since I switched it now shows Galaxy AI below connected devices in settings.
