o1-pro is "o1 on steroids" and was the first selling point of the $200/month Pro subscription but they later also added "Deep Research" and Operator to the Pro subscription.
For me I was sold on the consistency. o1 does really great at several programming problems, but o1-pro does great on these problems 4 of 4 tries. I get a good answer more often with o1-pro than with just o1, or even o3-mini-high.
o1-pro is indeed pretty great, but I find that I can iterate several times with Gemini 2.0 Pro Experimental (or whatever their latest reasoning model is called these days) between o1-pro's responses. It's almost too slow for interactive use cases.
