A query for "who is youyou cong?" correctly identifies the person in question - a professor at Tokyo Institute of Technology - but then the summary continues and says "His research includes ..." (Prof. Cong is a woman).
The search results without forcing an AI summary ("youyou cong") correctly point to her web page and include a snippet from it that answers the question well ("I am an assistant professor at ..."). It's just Claude hallucinating a gender in the AI summary.
Either get the gender right or don't invent one when it's not apparent from the source material. Probably, in this case, the latter - she doesn't list pronouns or gender on her web page, so avoiding having the AI summary make stuff up seems like the better solution.
