English-only ChatGPT pilot for Korean secondary-city travel recommendations
ChatGPT (gpt-5-mini) · April 30, 2026 · no-web-search fast mode
We asked ChatGPT six English-language travel questions about Korean cities on April 30, 2026: three open discovery prompts and three Busan-specific prompts. Busan ranked #1 in the "best secondary cities" answer, appeared prominently in the "weekend trips from Seoul" answer, and was referenced as the mainstream contrast point in the "hidden gems" framing (which positions hidden gems as places "without Busan crowds" and surfaces Gyeongju, Jeonju, Andong and Tongyeong instead). All three Busan-specific probes described the city accurately. The strongest AI associations were beaches, seafood, port-city identity, BIFF, and Gamcheon Culture Village. AI's most-mentioned Busan asset, Haeundae Beach, matches Busan's officially-promoted #1 asset. The pilot also surfaces a useful gap: BIFF, port identity, and food culture are prominent in AI answers but are not currently tracked as priority assets. This is a small sample — six calls, English only, single engine — so it proves the workflow, not the final market conclusion.
We asked ChatGPT 6 English-language questions: 3 open discovery prompt(s) and 3 Busan-specific probe(s). All answered cleanly. The cycle parsed, exported, and validated with 0 error envelope(s).
Citations are absent because this pilot intentionally disabled web search to test the fast live path.
