Is Carbon the next version of Argon? My understanding was that Argon is the middle-tier model (somewhere between OpenAI's Terra and Sol in position) whereas Carbon is supposed to be like Astra. This is assuming they don't have an even higher tier model upcoming, in which case Argon ~ Terra, Carbon ~ Sol and Element X (Plutonium?) ~ Astra.

Wild guess: maybe they are going with how abundant the elements are to scale the models. I'm no chemist so I don't know reliably how the relative abundance of Argon and Carbon works out, but Hydrogen is "well-known" as the most abundant element in the universe, so maybe that's why its the base model. But, this is essentially a trend of one, so not a trend at all, unless someone can verify it still works for Argon and Carbon.

Also I intuitively get that a sonnet is "shorter" than an opus (although Fable is less clear) - I have no idea what i'm even supposed to be comparing with google elements... Atomic number? I know hydrogen is the lowest and i guess argon is bigger than carbon but am I expected to know that? Or is it by weight? Argon's a gas so it's lighter than Carbon?

The sol/terra/astra, haiku/sonnet/opus clicked without needing to be explained

> Carbon is the next version of Argon. But Hydrogen is supposed to coexist with Carbon. Also no idea where the scheme is coming from, what elements should we expect.

The problem with using elements names simultaneously as both version numbers and product tiers, is that inevitably you will face a confusing collision or you will exhaust the space.
