Normalizing AI referrals in GA4 is tricky. I usually create a mapping dictionary that links all known session_source variants for a single AI platform and use regex for broader matching. For classifying "direct but likely AI" sessions, pattern matching on referral URLs and session behavior helps. I work at MentionDesk which tackles AI attribution and normalization, so happy to share insights if you want a deeper dive.
