#3Error messages matching Z.ai GLM I think are the simplest/most compelling. I had Opus 4.8 poke it and it came back with a couple different errors than the article mentions.
Matching the tokenizer is interesting tho

#4Another strong hint is that the uptime graph of GLM-5.3 by Z.ai is very similar to that of Ox Alpha:

#5Can someone explain why people care about that?
Both as in "Why is there a stealth launch like that in the first place?" but also "Why does it matter? Is it very good in something?"

Stealth launch: builds hype, allows them to collect user preference data and see where the model fails.
Why people care: it's free, decent, and people love a good mystery.

Aaah, free inference. Yeah that checks out and fits very well with weird Internet hype.
Okay, fair enough. Thanks!

I think the stranger thing is that people spend tens of hours doing analysis like this to hit an inevitably-expiring hype cycle that will give us a definitive answer shortly.

It's fun! Also it's an interesting commentary on where the AI industry is as a whole.
