As if 3 different preview versions of the same model is not confusing enough, the last two dates are 05-06 and 06-05. They could have held off for a day:)
In Canada, a third of the dates we see are British, and another third are American, so it’s really confusing. Thankfully y-m-d is now a legal format and seems to be gaining ground.
06-06 is unambiguously after 05-06 regardless of date format.
they are clearly trolling OpenAI's 4o and o4 models.
It makes you look even more stupid.
