Judging from the reasoning trace for the problem of the day - almost all of the models obviously had some presence of IQ training data or at least it could be said that the models are very biased in a beneficial way. From the beginning of the trace you kinda see that the model had already "figured it out" - the reasoning is done only for applying the basic arithmetics.

None of the models did actually "reason" about what the problem could possibly be - like none of them considered that more intricate patterns are possible in a 3x3 grid (having taken this kinds of test earlier in life, I still had a few seconds of indecision, thinking whether this is the same kind of test that I've seen and not some more elaborate one), and none of them tried solving the problem column-wise (it is still possible by the way) - personally, I think that indicates a strong bias present in the pretraining. For what it's worth, I would consider a model that would come up with at least a few different interpretations of the pattern while "reasoning" to be the most intelligent one - irrespective of the correctness of the answer.
