Surely it's size based: Sun (Sol) > Earth (Terra) > Moon (Luna)

Similar to Anthropic's size/length based naming: Opus > Sonnet > Haiku

These names seem easy to understand to me, and much clearer than suffixes like -max and -plus.

I'd agree it is similar to Anthropic's naming scheme, which I'd argue shares the same problems as this. It improves marketability/googlability, but decreases actual comprehension.

You don't actually explain why or how these names are "easy to understand" just state that they simply are. That's great; to me, they aren't obvious or intuitive at all. May have well just start randomly pointing at dictionary words.

I collect roman coins, with latin legends, so the sun/earth/moon references jumped out at me, and partly based on the opus/sonnet/haiku precedent I assumed that these names were referring to different model sizes/prices in a way that mapped to the names (Sun > Earth > Moon).

I'll admit though that until recently I never really thought about Anthropic's naming scheme as having meaning (an Opus being longer than a Sonnet, being longer than a Haiku).

It's just the latin tripping people up. If they had named them sun/earth/moon it would be clearer for some.

Or something like dog/puppy/sperm.

This demonstrates the problem with an education that has no emphasis on the liberal arts, such as critical thinking. No justification is needed for why and how these names are easy to understand.
