It's a quick way to say that the emperor still has no clothes.
We're boiling the oceans to train the models, and these are well-publicised failure modes. If they haven't fixed it, it seems to suggest they CAN'T fix it with the tools and architecture they have. So what other problems is it whiffing on that aren't trivially checkable?
If marketing boxed in the product and said "it does these ten things well", we might be willing to forgive limitations when we leave its wheelhouse. Nobody kvetches that Microsoft Word is an awful IDE, after all. But that would require a retreat from a public that's been promised Lt. Cmdr. Data in your pocket, and investors that have priced it as such.
OpenAI, because GPT-5 has only improved in terms of coding so as not to fall behind Anthropic. In addition, it does not consume more resources than its previous models.
In other aspects, there has been no improvement, it has declined slightly, or the improvement has been minimal. Does this mean that OpenAI and the sector are going to collapse?
Probably not, because there were only problems with the launch of this model. In the coming months, they will launch another model that solves this, although it may not.
It may not consume more resources, but the older models were already consuming way too many resources to pump out their bullshit machines
