I've been using o1 almost exclusively for the past couple months and have been impressed to the point where I don't feel the need to "upgrade" for a better model.
Are there benchmarks showing o3-mini performing better than o1?

You just have to use the models yourself and see. In my experience o3-mini is much worse than o1.
The fact they would exclude it from their benchmarks seems biased/desperate and makes me trust them less. They probably thought it was clever to leave o1 out, something like "o3 is the newest model lets just compare against that", but I think for anyone paying attention that decision will backfire.
