Pilot finding

Busan is strongly visible in this small English-only ChatGPT pilot. AI's most-mentioned Busan asset, Haeundae Beach, matches Busan's officially-promoted #1 asset. AI also surfaces BIFF, port identity, and food culture as prominent associations — none of which are currently tracked as priority assets, suggesting a coverage gap in the official asset definition.
