They should at least tell us the atomic mass they're using.

If it's based on carbon-14 it will lose half its model weights in 5,730 years; if it's based on carbon-12, it's a stable release.

By the way things are going in the industry, I think Gemini 4 Carbon's lead will only persist for the half-life of Francium-223.
reply
Depends. If it is uranium, the lead will only continue to increase.

Followed naturally by Gemini Series S and Gemini Series X.

In all seriousness, if Google must continue gambling on pre-train runs, at least have a useful naming scheme. Like the month it was post-trained and the parameter count. At least that’d provide some insight.

How is this any different than terra, sol etc or leopard, yosemite etc, or model x, y, 3, s ..
reply
Don't know about the leopard and model x, but at least in the case of OpenAI luna > Terra > Sol > Astra is a pretty obvious size progression.

But I come from a latin language background, so maybe I'm a bit biased there.

reply
At the risk of taking a geocentric position, my gut feel is Terra -> Luna -> Sol -> Astra. Sorting algorithm is distance from observer.

Size wise Astra is not categorically bigger than Sol, both in absolute terms and the observed size.

reply
Astra is latin for "stars", so basically the Galaxy (or Universe as a whole) which is categorically bigger than Sol, the sun, a single star.

The naming makes perfect sense to me, the sorting algorithm is size, both for the names and for the models themselves. Smaller things represent smaller models, and vice versa.

reply
> the Galaxy (or Universe as a whole) which is categorically bigger than Sol, the sun, a single star.

I would need to be a complete moron to argue with this. Humor me, however. My Latin skills end at remembering "Romani Ite Domum" and English is not my first language.

My layman reading of the names: there is one Terra, one Luna and one Sol => "Astra" is singular.

Now that I googled it, I understand that "Astra" literally means the "Stars" category. I would not have thought that they called a single star "Astrum". On the other hand, I am not sure if it means "Galaxy" in modern sense, but we're entering Roman Astronomy territory, where I am even less knowledgeable than in the language.

Sol is a star, so having a dedicated Stars category on the naming scale makes less sense. Treating Astra as Stars set without Sol, the "distance from observer" argument still kind of makes sense.

reply
> My layman reading of the names: there is one Terra, one Luna and one Sol => "Astra" is singular.

That is incorrect. "Astra" is Latin for "stars" (plural). The singular would be "astrum".

reply
Ad Astra. To the stars.
reply
Size is by far the most obvious one, at least for me.
reply
Yeah, this was my initial thought as well... I guess they didn't ask anyone before choosing the new naming scheme. But that isn't particularly surprising.

It doesn't help that the moon and sun have roughly the same apparent size in the sky

I didnt know this but apparently Astra is the plural of astrum (latin for star).

In the multiverse version, the model isn’t any smarter, but it’s evil.

Astra > Sol > Terra > Luna seems clear enough to me

Leopard (10.5) and Yosemite (10.10) both came with clear version numbers

Model X and Model Y are siblings which do not have a clear hierarchical relationship

Gemini 4 Carbon and Gemini 4 Argon are rather difficult for me to tell at a glance

reply
Confusingly, Carbon is another model in the same size class as Argon. Every other lab would have just called it Gemini 4.1 Argon.
reply
AFAIK they are all (Barium, Argon, Carbon) different checkpoints of the same (ongoing) training run
reply
Luna/Terra/Sol/Astra make perfect sense, it indicates model tier/size with larger celestial body representing larger model.

Same for Anthropic, consistent model tier naming reused across model generations.

Those are just like i3/i5/i7 or M-series Pro/Max/Ultra.

But Carbon seems to be full replacement of Argon announced two weeks ago, they're same price. So Argon doesn't mean anything, they just picked random element.

reply
Both openai and anthropic names feel much more confusing than cpu names to me.

They'd be fine except every named model has multiple numbered versions, with no consistent relatioship between cost or capability corresponding to the version numbers going up or down.

He is extremely unserious. Did you miss the part where he cheated at Diablo to try to seem to be some kind of dedicated gamer? Or, y'know, the whole Cybertruck? Or the "pedo guy" comment after his harebrained submersible idea went nowhere and a regular diver saved a bunch of Thai kids?

He's always been deeply unserious.

Do both like OAI and Anthropic do.
reply
terra/sol or opus/haiku give an indication of size (the sun is bigger than the earth, opus is larger than a haiku). Carbon is smaller than argon (periodic table speaking), so that's no longer a helpful way of thinking about the model sizes...

It does more than merely being different, it also collides with the name of another Google project: the Carbon programming language.

Don't worry, the name was chosen as a reminder to everyone of the environmental impact.
reply
True. And if Carbon (6) is better than Argon (18), wouldn't that make Hydrogen (1) the ultimate Gemini model, or will the next model jump to another random element?

  O, B, Sc, U, Re?
  Ra, Nd?
reply
I cannot figure out how to use anything better than 3.1 pro even on a paying account. There’s 3.8 flash and 3.5 flashlight. I can’t figure out which one is better so I’ve given up trying. It’s just too confusing. there’s too much competition for this type of confusion for the customer.
reply
3.8 flash is probably the sweet spot for most of your use cases. I’ve tried argon once or twice, and haven’t noticed it being better than flash for my dev tasks. Likewise, DeepSeek 4.1 Flash still seems better than any Google model I have access to.
reply
Yeah...some people complain about OpenAI and Anthropic's model naming schemes but at least it's fairly obvious from the names how they scale, how is ordering for Argon and Carbon supposed to be interpreted? And there's the 3.x and 2.x models which I don't think have elemental names (at least not public ones). The obvious atomic number or standard weight approach doesn't work.
reply
i'm also confused. my speculation is they trained a lot of different versions/revisions of models. maybe they're different base architectures, maybe they're different pretraining sets, or maybe they're different RL/post training regimes, and we're just seeing a few of them. still not sure what the names would mean internally though even in that case

or I'm dumb and its just elements with names starting with A, B, C

reply
I am surprised there is no Gemini: will return in Avengers Doomsday.
reply
Argon - first version, Bismuth - internal, Carbon - second version for the public if I had to make a wild guess.
reply
Other sources say that what was publicly released as Argon was already the second version named Barium internally. So there was a separate internal Argon and public Argon was Barium. Not confusing at all for them! https://www.reddit.com/r/GeminiAI/comments/1x292ly/a_new_che...
reply
The internal joke was that we're even scaling the off-by-one errors; Gemini 4 was not the fourth major model version.
reply
Still better than Anthropic. If I create someday doomsday device, its turn off code will be to sort Anthropic models by strength given only their names, without access to the internet.
reply
Before Mythos/Fable they were simply size-ordered. A Haiku is a small poem of 3 lines, a Sonnet has 14 lines and an Opus is a larger work.

I suppose a Fable is seen as larger. But some of them can be quite short, and not generally considered poetry.

reply
I found Anthropic to be pretty intuitive.
reply
Clearly, Google has already fired their marketing department and Gemini sucks at this job.

Maybe it thought the names are clear and intuitive (for an LLM perhaps).

reply
Alphabetically sorting chemical elements sounds like something _only_ a marketing department could think of.
reply
Literally. If only elements came already presorted by some kind of a key already...
reply
Hmm..they did come up with Bard.
reply
This naming strategy is bizarre.

There are no good elements for D; Dysprosium is the only one, and it's a mouthful. There are no good elements for E; Europium is the only one and would seem political. Is Fluorine their next release? (And then Gallium or Gadolinium?)

After Carbon, they should just update to Gemini 4.1 or 4.5 or whatever, and drop the random unrelated elements.

I don't think calling a model europium will be seen as political if it is a clear line of alphabetical animals, but who knows what the fine president can cook up

What's so confusing? Gemini is a constellation. Constellations are likely made of carbon and sometimes are made out of flash. And sometimes there's argon involved. Seems to make perfect sense to me. ¯\_(ツ)_/¯
reply
I don't mind Carbon, Argon kind of throws me off because my brain autocompletes to Argonian... I still have no idea what the different ones from OpenAI mean. Can we just go back to "Silver, Gold, Platinum" for naming things? Something simple we've all understood, always.

Reading the Argonian reference made my brain immediately think “The Lusty Carbonian Maid”
