It’s not… why do I need to translate from Latin (or wherever these come from) to understand them? Opus, Sonnet, and Haiku do the same thing, and are widely known words. Not to mention all LLMs do is generate tokens; I prefer the homage to writing over a space reference.

Not a lot, but occasionally. I was familiar with the words.

It really doesn't.
The one real weakness of Anthropic's naming is that Fable doesn't fit. A fable is typically a fairly short story whereas I think of an opus (if a written work) as being at least a long book and maybe a whole collection of books.
I find Luna vs Terra more clear. I know what a haiku is only because it hss some sort of hype factor among certain crowds. But I have no idea what a sonnet is, I heard of the word but never seen or written one. Opus vaguely reminds me of something in Greek mythology but also no idea what that, let alone the apparent implication that it's supposed to be longer than a sonnet.
haiku (the model family) was not inherently inferior to its larger, more expensive siblings. Sometimes you prefer a cheap, fast model, just like how sometimes you prefer a shorter poem.
