It's a different model and designed to 'think very hard' about issues. It's basically a 'very extended thinking mixed with research' type of solution.

While the 'research' solutions tend to go very wide and come back with a 'paper' the Pro model seems to do an exhaustive amount of thinking combined with research, and tries to integrate findings. I think it goes down a lot of rabbit holes.

I find it's by far the best way to find solutions to hard problems, but it typically does require a 'hard problem' in order to shine.

And it takes an enormous amount of time. Ito could be essentially a form of 'saturating the problem with tokens'. It's OAI's most expensive model by far. A prompt usually costs me $1-3 if paying per token.
