I usually use English to talk to Gemini, but the other day I wanted to try and find out the original band of a Siberian punk song that I have carried around in my music collection since time immemorial. Problem is the tags are all over the place in this genre and there are situations where "Foo-Bar" and "Foobar" are two completely different bands. Gemini was clearly trained on some genre forums from late 90s which are... shall I say non-PC by any stretch of the term.
In the middle of the conversation it randomly switched from English to Russian and clearly struggled to maintain the tone imposed by the built-in prompt.
