Either it can demo some pretty clever, but still limited, features resulting in math skills OR it's literally the best search engine ever invented.

Both are precisely true. It is a better search engine than anything else -- which, while true, is something you won't realize unless you've used the non-free 'pro research' features from Google and/or OpenAI. And it can perform limited but increasingly-capable reasoning about what it finds before presenting the results to the user.

Note that no online Web search or tool usage at all was involved in the recent IMO results. I think a lot of people missed that little detail.
