Of these, some are mostly obsolete: GPT-4 and GPT-4 Turbo are worse than GPT-4o in both speed and capabilities. o1 is worse than o3-mini-high in most aspects.

Then, some are not available yet: o3 and o4-mini. GPT-4.1 I haven't played with enough to give you my opinion on.

Among the rest, it depends on what you're looking for:

Multi-modal: GPT-4o > everything else

Reasoning: o1-pro > o3-mini-high > o3-mini

Speed: GPT-4o > o3-mini > o3-mini-high > o1-pro

(My personal favorite is o3-mini-high for most things, as it has a good tradeoff between speed and reasoning. Although I use 4o for simpler queries.)

So where was o1-pro in the comparisons in OpenAI's article? I just don't trust any of these first party benchmarks any more.

Is 4.5 not strictly better than 4o?
