In my experience (currently my only mobile browser) it will remember last setting, prefer no ai if unknown userbase preference and if there’s a known userbase preference it will do either yours or userbase depending on settings and version. Search assist (ai search summary) is on by default but will not force a generated answer. All of these settings have been easy and intuitive for me to toggle, though it is chromium based. I have seen better filtering and results on some searches on ddg than google, but that bar is so low bing can sometimes clear it.
I don’t know offhand but I strongly suspect everything related to AI is defaulted to on.
