I have been playing around with various GPTs lately by getting them to help me with my management consulting work. Usually analyzing docs and merging them or two me what the overlap is, etc.

My experience with Gemini pro is that it often completely and spectacularly misunderstands the ask. No other GPT comes close to getting it that wrong. As a result, I don't have a high level of confidence in it.

I find Mixtral to be quite impressive. It is by far the fastest and gives me good output. At least for big documents kind of work.
