Why do they brag about not using a theorem prover? To me, whatever tool helps the model perform, go for it.
Besides, they still specialized Gemini for the IMO in other ways:

Because this highlights that Gemini actually reasoned independently of other tools. That is a massive quantum leap in AI/ML. Abstract reasoning is arguably the basis of cognition.
