Google's is just random.
They botched it.
A haiku is a short poem. A sonnet is a longer work. An opus is a great work. Mythos is a connected body of works.
As with Open AI, Luna --> Terra --> Sol --> Astra from smallest to largest. Very straightforward.
With Google it's totally incoherent. Hydrogen --> Argon --> Carbon!?
Hydrogen is small, but it's the most abundant element in the universe by far. Argon is >3x larger than carbon by molecular mass, though carbon is more abundant. It's impossible to determine what's supposed to be smaller and what's supposed to be larger.
Letters of the alphabet: Also makes no sense. There was a theory that Argon = A, that there was an unreleased B model (Bismuth or Barium or something), Carbon = C, etc. (Similar to Intel's MMORPG-inspired Alchemist --> Battlemage --> Celestial...) Hydrogen broke this notion.
It's just completely incoherent.
Also, the biggest being Astra is a bit confusing. Sol is also a star.
Furthermore, unless you know they’re supposed to be ordered by size you can’t know which is best.
I don't think these are as difficult as you're making them sound? I think the majority of people who will care what model they're using will know "lunar", "terrestrial", "solar", "astronomy" etc?
Ar - C - H - ?
Fable is essentially Mythos but with guard rails added.
I think OpenAI's names are clearest. In most people's understanding, moon < Earth < sun < stars.

Using constantly changing names for tiers is a bad idea. Unless the tiers are pre-existing (bronze, silver, gold).
Fables are short.
They should have used "saga" / "epic" / "cycle" / "series" / "universe".
My only real complaint with Google is they regularly change names for seemingly no reason. I'm still out here saying "Gemini" when I type "agy" and I don't bother saying "Anti gravity" because I assume that name won't exist in a year or two.
