In order of sophistication and cost, the models are Hydrogen -> Argon -> Carbon.

What kind of ordering is that?!?

With the introduction of Hydrogen, it's no longer ordered alphabetically. That would be Argon → Carbon → Hydrogen.

And it never was ordered by atomic mass, which is arguably the best ordering if you're going to name your model classes after chemical elements. That would be Hydrogen → Carbon → Argon.

It's also not ordered by prevalence in the universe. That ordering would also be Hydrogen → Carbon → Argon.

It's not ordered by electronegativity, boiling point, melting point, or any other remotely defensible chemical property I can think of.

It's not even ordered by letter count, Scrabble score, or NFPA 704 Flammability Rating, all of which would be Argon → Carbon → Hydrogen.

Billions of people will now be exposed to a model that crushes sonnet 5.5 on benchmarks (in google ai search suggestions).

I kinda miss dumb ai in a way actually, was a certain charm to it
