That's what I thought but there's slightly more than that.
The writer tried to trick ChatGPT 5, saying Vermont has no R in it. ChatGPT did say "wait, it does". But then when pushed it said, "oh right there is no R in Vermont".
I mean... the inability to know what it knows or not is a real problem for most use cases...
I don't think this is true, although maybe in some places.
For example, the more gas a business uses in the Netherlands, the less they generally pay per unit. This is terrible for our carbon footprint, where we basically subsidize the worst emitters. ๐
