It's reasonable to ask for sources when an opinion is phrased as a fact, as GGP did. I don't see how you got that it was _unmistakably_ an opinion from that comment.
There is no way to deduce by intuition alone that GPT-5 == GPT-4o. So either that person has some information the rest of us aren't privy to, or it's an opinion phrased as a fact. In either case, it deserves clarification.
On a second read I see that the comment notes that it is intended as speculation, but still it seems rather confident in its own accuracy and I am not even sure it's wrong, but just looking for something that warrants the confidence.
I wrote my comment that way, based on my personal memories of the news cycle between gpt-4 and gpt-4o, and the claims raised by OpenAI about gpt-4o. The hype before 4o release was overwhelming, people have expected the same step up as between 3 and 4, and there were constant "leaks" from supposed insiders that gpt-5 is just at the horizon and will come out soon. And then they release 4o, which was a big standalone release, not some fine tuning like turbo or whatever else they made before.
Looking at the benchmarks it was also very expected in my opinion. Sure, the absolute results are/were sky high, but results relative to the previous gen were not exponential now, they were comparatively smaller than between 2 and 3, or 3 and 4. So I'm guessing that they have invested and worked for 2023-2024 on a brand new model, and branded it according to the model results.
That was clearly phrased like a fact, which may or may not be correct. If it had been phrased like an opinion we wouldn't be having this conversation...
The problem is once you believe their fact is wrong, just say "I think you're wrong <insert rest of comment>". Innocently asking for a source as if you're still on the fence is just performative and leads to these conversations where both sides just end up talking past each other:
A source for one underpinning of the incorrect fact comes up, then "well but that only proves X part of it, can you prove Y" and so on.
tl;dr I just find the quality of discourse is much higher when people are direct.
> I just find the quality of discourse is much higher when people are direct.
Well this certainly is a lot of work to make a mountain out of a mole hill, and I'm not sure it increases the quality of discussion either.
In any case, I think saying bold shit followed up with "it's speculation, but it's OBVIOUS speculation" is worth asking for some evidence. Obvious speculation implies it's sourced from something other than personal gut feeling.
To echo a sibling comment:
> Every time someone says their speculation is "obvious" it rings every possible alarm bell for someone who has completely lost grasp of the ability to distinguish between facts and speculation.
