Talents would refer to several skills and abilities, rather than to the persons possessing them. Talent can be a singular noun, referring to a person or people who are talented. From the dictionary, i know if talent refers to sexually attractive people, it is uncountable.

I probably hear and read at more than any other preposition after the adjective talented:
There are lots of talent (s) in the pop music field in korea.
As you've noted, for is the ordinary preposition to use after.
