There is generally something about the Gemini models which feels a bit different than Claude, ChatGPT or Mistral.
I always have the feeling that I'm chatting with a model oriented towards engineering tasks. The seriousness, lack of interest of being humorous or cool.
I don't know if this is because I interact with Gemini only through AI Studio, and it may have different system instructions (apart from those one can add oneself, which I never do) than the one at gemini.google.com.
I never use gemini.google.com because of the lack of a simple export feature. And it's not even possible to save one chat to disk (well, neither do the others), I just wish it did.
AI Studio saving to Google Drive is really useful. I lets you download the chat, strip it of verbose things like the thinking process, and reuse it in a new chat.
I wish gemini.google.com had a "Save as Markdown" per answer and for the complete chat (with a toggle to include/exclude the thinking process). Then it would be a no brainer for me.
It's the same as if Google Docs would not have an "Download.." menu entry but you could only "save" the documents via Takeout.
