This is the most important class of models to keep watch. These are the ones that are going be to workhorses in the post-tokenmaxxing clarity

jrflo 31 minutes ago | parent

Disagree, Opus-tier models are the workhorses. You can get a ton done with them on a $100 subscription.

vallerie 28 minutes ago | parent

And for those on API billing? Opus is still quite pricy for what you're getting done with it.

> And for those on API billing?

Opus-tier on open models and local hardware.

XCSme 19 minutes ago | parent

Why stay on API billing? A $200 monthly subscription has a crazy amount of usage and more than enough for a couple of concurrent projects.

demibabs 18 minutes ago | parent

Enterprises with more than 150 seats have to pay API costs.

sz4kerto 15 minutes ago | parent

Because you can't get subscription if your company has more than 150 users.

jrflo 17 minutes ago | parent

If you're on API billing then presumably you're a business, and $1,000 a month is still reasonable for that quality of work

szatkus 7 minutes ago | parent

Those subscriptions won't be subsidized forever. At least not as much as they are today.

raincole 25 minutes ago | parent

Assuming the price would converge to the subscription price, not the API price.

demibabs 19 minutes ago | parent

For users who pay subscription costs, 100% right.

But for enterprises, who have to pay API costs with no discounts, no way.

I like that you gave an argument and careful reasoning instead of just a vague claim based on common meme about ejaculation.

How is tokenmaxxing like ejaculating exactly? I don't follow the analogy.

ezrabuenk 15 minutes ago | parent

I think he's just saying tokenmaxxing is a temporary hype lol, probably fueled by subsidized subscriptions. When that's over, these cheaper models might get more usage.

pixelready 5 minutes ago | parent

Why is this exchange reminding me of that You Can See Everything documentary?

The analogy made sense to me: Tokenmaxxing policies were the result of an irrational drive by execs who just craved an, ahem, explosion of metrics due to the excitement over new technology. Now that cost sensitivities are setting in, there’s a growing sense of unease that maybe they were in an altered state when they created the mess and now that the excitement has passed they have to clean it up.

james2doyle 38 minutes ago | parent

Their naming scheme seems a bit tough to follow. But it does seem like they finally learned their lesson and announced something at the same time it's actually available!

hodder 38 minutes ago | parent

Maybe I'm not on the latest models (I do actually pay the min plan), but just this week I tried Gemini again. It still doesn't even get the current date/time of day correct. If it cant do that, I cant trust any output from it. I have no idea how Google fumbled so badly, but benchmark scores don't mean a thing if you cant even get your LLM to output the current date and time correctly.

You could vibe code a better LLM with Fable than what they have delivered. It is embarassing.

iamdelirium 35 minutes ago | parent

What? I just asked it what time it was in my Gemini app and it told me.

What is your prompt?

sergiotapia 37 minutes ago | parent

Aren't Google leaders embarrassed that the first thing I think of when I see their models drop is: I will see if I can call it from openrouter?

Why are there 7 different ways to call this model from Google? Which one should I use?

Is no one at the wheel calling the shots at Google and it's a PIP every man for himself? I want to try them out, don't know how.

mattlondon 35 minutes ago | parent

It's in the second paragraph of the article.

sergiotapia 35 minutes ago | parent

"for all tiers of Google AI Studio, the Gemini API, Gemini for business, the Gemini app, Google Search, and paid Google AI Pro and Ultra subscribers in Google Antigravity."

So which one of these six options is the one I should use?

mattlondon 30 minutes ago | parent

Whichever one suits your needs.

AI studio if you want to just try it out for some code things (think of it as a web IDE)

API if you want it to use it as an API.

For business if you are an enterprise.

Antigravity

Or just you know - just go to Google.com and search for something. It's really not hard.

This instapost "wah I don't know how to use it wah" from anyone as soon as Google release a model is getting tiring - change the record please.

qlte 19 minutes ago | parent

Same question as whether you should be using the latest Claude Opus model from Claude Chat, Claude App, Claude Code (via Claude Pro/Max/Ultra subscription), Claude Code (via API), Claude Platform, Claude on AWS Bedrock, Claude on Azure Foundry, Claude Managed Agents, Claude Cowork, etc?

JacobAsmuth 8 minutes ago | parent

When you call it through OpenRouter you're using the API.

You know how Claude Code is like a little program that your computer can run which lets you talk to Claude? Well Gemini is actually really similar! If that's more your speed, you should use Antigravity.

But if all of this is feeling really overwhelming and you just want something simple, I would recommend just Googling it! Hydrogen will be the one generating the response :)

thereitgoes456 37 minutes ago | parent

Is this a replacement for Flash-Lite? Because it’s being used to serve answers for Search.

The new naming scheme seems shockingly poor though, “Pro” and “Flash” made intuitive sense to me, and Anthropic and OpenAI kept a sense of scale. Nobody is going to intuitively understand “Oh yes, Hydrogen is smaller than Carbon”, even though it is.

cflewis 33 minutes ago | parent

I don't believe so. From my use I think it is a Flash model through and through.

I have found it a good subagent workhorse for code implementation, with some higher level model doing the spec and review.

npn 30 minutes ago | parent

No. It has the same price with 3.8 flash (with no introduction price it seems)

JacobAsmuth 37 minutes ago | parent

I think a new default free model for AI Mode being so close to the frontier will be a massive jump in perceived AI intelligence by the general public.

redox99 23 minutes ago | parent

It will be the same as these smaller models from OAI and Ant. Strong in benchmarks but pretty bad in real world use.

I've read this same comment every time a new Luna came out, and the difference between free GPT (Luna) and paid (Sol and Astra) is still outrageous for general use.

WarmWash 19 minutes ago | parent

3.8 flash was easily the best general everyday person model yet though

notatoad 10 minutes ago | parent

3.8 flash was never served to free users on google though?

JacobAsmuth 7 minutes ago | parent

3.8 Flash was served to free users in AI Mode IIRC

JacobAsmuth 18 minutes ago | parent

I think this is a completely different class from Luna and is much more akin to 6.1 Sol in terms of capabilities and general intelligence.

jawns 36 minutes ago | parent

The naming of these Gemini 4 models is ridiculous.

In order of sophistication and cost, the models are Hydrogen -> Argon -> Carbon.

What kind of ordering is that?!?

With the introduction of Hydrogen, it's no longer ordered alphabetically. That would be Argon → Carbon → Hydrogen.

And it never was ordered by atomic mass, which is arguably the best ordering if you're going to name your model classes after chemical elements. That would be Hydrogen → Carbon → Argon.

It's also not ordered by prevalence in the universe. That ordering would also be Hydrogen → Carbon → Argon.

It's not ordered by electronegativity, boiling point, melting point, or any other remotely defensible chemical property I can think of.

It's not even ordered by letter count, Scrabble score, or NFPA 704 Flammability Rating, all of which would be Argon → Carbon → Hydrogen.

InsideOutSanta 29 minutes ago | parent

I know some people are still a bit confused by astra, sol, terra, and luna, but at least you can explain the reasoning and it makes sense. Google's new naming scheme is just pure luna...cy.

Iolaum 28 minutes ago | parent

I don't know why but this post reminded me of the show(books) Altered Carbon.

Also totally agree. What a bad way to name models...

gpm 28 minutes ago | parent

Density at standard temperature and pressure? Carbon admittedly has a number of forms at STP but they're all solid and thus heavier than argon gas.

daemonologist 27 minutes ago | parent

Density of the most common (on Earth) allotropes at STP, perhaps?

Or maybe they just pick them out of a hat.

jrflo 26 minutes ago | parent

The choice is really odd. Hydrogen and Carbon could have an organic chemistry theme going if they chose Oxygen, but then they go with Argon? Anthropic and Open AI have the names figured out in terms of obvious size: Luna->Terra->Sol->Astra and Haiku->Sonnet->Opus->Fable->Mythos makes intuitive sense. I have no idea how the Google model size class works.

aquariusDue 24 minutes ago | parent

Yeah, they really fumbled the naming scheme for this batch of models.

At this point even using Starbucks sizes would be better.

wry_xy 23 minutes ago | parent

We'll know they've achieved super intelligence when tech companies suddenly have sensible product names.

amanda4 23 minutes ago | parent

Per Business Insider[0], Argon and Carbon were part of an alphabetical lineup:

> An internal document shows that Google has tested a series of Gemini 4 models, internally named Argon, Barium, and Carbon.

Then I suppose they tacked on Hydrogen since it's supposed to be a "light" model and hydrogen is the lightest element. I agree that it's super confusing though.

nodejs release names

alphabetical skipping the weird names

next would be iron krypton and lithium

mattlondon 16 minutes ago | parent

+1 to this the naming is totally opaque and ridiculous.

There is no hint of what each one does. I get that these were internal code names, fine, but to everyone outside Google it's not helpful to have these meaningless names.

ChatGPT and Claude aren't much better - there is still quite a lot of assumed knowledge there assuming you know what e.g. a sonnet is and what an opus is - but at least if you squint there is something there.

Google's names just seem to be randomly generated.

Maybe they were worried that the 3.1 Pro model being around for so lunch ruined the brand? But 3.8 Flash was pretty decent I thought so it's not like "flash" was burnt. I dunno.

prodigycorp 36 minutes ago | parent

Google team: these names are an embarrassment

The naming scheme alone has no rhyme or reason. Model names should not be a source of cognitive load.

mv4 33 minutes ago | parent

Indeed. That's why when I had to name my product I named it after a cat.

medler 31 minutes ago | parent

It is no more confusing than the naming schemes used by OpenAI and Anthropic

jug 24 minutes ago | parent

OpenAI is at least arranged by size of celestial feature. Anthropic did arrange them by size of a written work. But I think Fable and Mythos made it a little weird. As for Google, no idea other than Hydrogen is small so at least that kind of tracks.

Having said this, I don't defend this trend at all and also think a model picker ought to be good enough with at most three tiers rather than five or so with sometimes like five effort levels each for 25 combos. I refuse to believe we need this granularity.

techmunky 12 minutes ago | parent

OpenAI - Celestial body size.

Anthropic - Literary scale.

Google - random elements with no clear relation to model value/capacity.

yewenjie 34 minutes ago | parent

Honestly I cannot keep up with the naming conventions that keep changing every month.

Argon, Carbon, Hydrogen?

Luna, Terra, Sol, Astra, Betelgeuse?

modeless 34 minutes ago | parent

This is a good blog post because of the graphs comparing directly to Terra and Sonnet for both wall-clock time and cost per task. This is the exact information I'm looking for.

My TL;DR is: seems like a better choice than Sonnet in areas outside of coding, and at high reasoning it's smarter than Terra but somewhat more expensive.

WarmWash 33 minutes ago | parent

I really hope hydrogen keeps the excellent conversational ability of 3.8 flash. For brainstorming or even decoding the dense output of the powerhouse models, flash was a real delight to use. Its the first non-SOTA model that I would actually go to often over the larger models, it was fast, plenty smart enough, and generally wrote really well. Here's to hoping hydrogen keeps that up

onlyrealcuzzo 32 minutes ago | parent

Pretty big Gemini fan, but my initial results with Hydrogen and Carbon are disappointing.

They are trading improvements on pass@1 pointless benchmarks for worse disasters at p90/99 that you're going to hit every week in agentic workflows (if not daily):

overreach (doing more than asked), overwork (when it should have failed fast), harm (doing the opposite of what was asked), orthogonal work (doing something completely unrelated to what was asked), etc.

Google doesn't seem to be the only lab making this trade...

The set of benchmarks they released are disappointing. 10 mostly random benchmarks. Really?

ComputerGuru 26 minutes ago | parent

No one on HN seems to get that agentic workflows are not the only name in the game. Everyone doing agentic development is either on a plan or with a custom enterprise offering, either way using higher-performing models. These entry level models are (also) for building apps on top of while you are paying API prices.

theplumber 32 minutes ago | parent

So a pretty mediocre model at best on par with the open Chinese models. At least the Chinese models have a coherent naming

iamdelirium 23 minutes ago | parent

Looks like they are releasing these... periodically!

ComputerGuru 29 minutes ago | parent

As this is a) being served in Search, b) supposed to be 2.5x faster than 3.8 Flash, c) the element with lowest atomic weight; I deduce that, despite being more capable than 3.8 Flash, now the “entry level” model set to replace 3.5 Flash Lite.

But it is priced the same as the non-discounted 3.8 Flash, considerably higher than what anyone is paying today for 3.8 Flash or 3.5 Flash Lite or the deprecated 3.0/2.x Gemini models. How does this work? Is Google abandoning the “fast and cheap” tier? That seems like a mistake since plenty of workflows are absolutely price inelastic, meaning when the 3.8 Flash discount ends at EOY, lots of current enterprise Gemini customers would have to take their business to another shop??

pqdbr 24 minutes ago | parent

Same impression here. If this is Google's strategy we'll have to migrate to Luna, because costs are already high for our workload on 3.8 Flash (which in itself was already a 40% increase compared to 3.7 flash due to being more verbose and thinking more) and this now doubles cost once again.

amarcheschi 23 minutes ago | parent

Isn't something open weight cheaper (and probably better as well)?

ComputerGuru 20 minutes ago | parent

Depends on your needs. Gemini Flash has best bang for your buck on visual tasks and best multilingual support/intelligence for non-Western/non-East-Asian languages; better than paid or OSS alternatives.

amarcheschi 14 minutes ago | parent

Yes I gave for granted textual tasks but they're not the only ones. If I remember correctly, mistral large should be good as well on image tasks while being cheap(er). I never had to do anything with less common languages tho

ComputerGuru 22 minutes ago | parent

Yeah, and they rug-pulled 3.7 very quickly, silently redirecting to 3.8 Flash. Raised our prices and broke some workflows.

netrem 19 minutes ago | parent

In the Gemini app it's replaced Flash. Lite is still there.

irthomasthomas 14 minutes ago | parent

But that's an old model, and if they replace it they have no smaller element to use for it's name. I guess it would have to be Hydrogen Light.

egeozcan 8 minutes ago | parent

I suppose they could name it proton or hydron.

agildehaus 6 minutes ago | parent

Quark/Neutrino/Axion/Tachyon.

iamdelirium 14 minutes ago | parent

The fact that there is still a flash lite dropdown in Gemini points to them keeping the flash lite model family.

irthomasthomas 13 minutes ago | parent

So all models will be named after elements except Flash Light? Or maybe the next version will be named Hydrogen Light?

TacticalCoder 29 minutes ago | parent

Are we going to talk about naming and confusing ways to access it, or are we going to discuss how capable the model is?

Every single time a Google model comes out, an army of Anthropic shills sidetrack the discussion.

Can we look at what the model does and discuss whether Google is still in the game or not? (naming models and whether you need to access it by clicking a drop-down menu or making a prayer ain't really relevant)

dvaplima 26 minutes ago | parent

Argon, Carbon, now Hydrogen. If Google keeps climbing the periodic table, the roadmap writes itself: Californium finds gold in your codebase (enterprise only)

whinvik 26 minutes ago | parent

The pricing on these models make really little sense. This is $1.5. Argon is $2. Carbon is also $2 for now.

Feel like this pricing only makes sense for a product where you don't even select the model. Maybe Antigravity is like that.

iamdelirium 13 minutes ago | parent

Isn't $2 the intro price for Argon and Carbon?

JV00 25 minutes ago | parent

Personally I found my usage of llms bimodal, I only have uses for the top frontier models (for research and development) or for the cheapest and fastest ones (to use in production for consolidated, simple flows). I am curious what people find the mid tier models useful for.

XCSme 18 minutes ago | parent

Same, I either use xhigh on best model, or use cheapest and fastest models (mercury/jev/haiku/luna)

XCSme 16 minutes ago | parent

I feel like people use medium models thinking they are saving money, but in the end, it ends up wasting more time and tokens theough the increased rate of issues/bugs.

If the highest tier model makes even one or two fewer mistakes that require human intervantion, that almost makes it a no-brainer choice for production.

harryVic 25 minutes ago | parent

Their super smart recursively improving ASI models didn't tell them this naming is absolutely terrible?

zetazzed 23 minutes ago | parent

Terrible naming convention on the low-end, because what do you do if you make something smaller than Hydrogen next? Gemini 5 Electron?

On the high-end, I feel like there is an implicit promise that if they keep releasing larger models and go past Oganesson (118), they are on the hook for AI-discovering a new stable element, so that is fair at least.

jeremyjjj 19 minutes ago | parent

Good they are able to replace Flash. And cool this is available to everyone via search. But I still don’t understand Googles strategy with these new models.

For pro sub, Argon is still very limited and Carbon is only available on Ultra. This is not competitive at all. To say nothing of also being locked into Antigravity.

aizk 18 minutes ago | parent

krmmalik 12 minutes ago | parent

I'm really enjoying all these Gemini releases. I know a lot of people keep saying Google is too far behind in the race and that they dropped the ball to early but I don't feel that way at all. I had both Opus and Fable try to find a discreet bug in my codebase and both models assured me I had nothing to worry about and was probably overthinking. Argon was the only model that got to the bottom of the matter and developed the fix for me. I constantly find the Gemini models perform better in the real world as compared to the other frontier models and I also find they have less of the AI-isms that many of us have now come to associate with ChatGPT and Claude. Gemini feels like you're speaking to a comrade. Claude feels like you're speaking to a friend and it's an important distinction I feel.

vander_elst 9 minutes ago | parent

Can anyone understand the logic behind the names? Argon, hydrogen, carbon, what is the mental model one should use to understand where they fit, or what comes before/after?

Haiku, sonnet, opus.. is ok

terra, Luna, Sol... is also ok..

but this?

wds 8 minutes ago | parent

This was rolled out RIGHT away, as when I just went to use Gemini, seeing 3.8 Flash be replaced with "4 Hydrogen" was less hype and more a thought along the line of "What [on Earth] is Gemini Hydrogen???", then me going here to figure it out.

This model naming scheme works for separate products, but using elements, molecules, etc. for products you're supposed to compare with each other... Not very helpful.

If anything, my intuition would say that Hydrogen is more powerful than Argon... I don't know. Not liking this naming scheme trend.

lbarrow 6 minutes ago | parent

The naming of this stuff is so bad. Hydrogen (1) is dumber than Carbon (6), sure. But Carbon (6) is smarter than Argon (18)!

The labs use a pretty clear progression: Luna -> Terra -> Sol -> Astra; Haiku -> Sonnet -> Opus -> Fable/Mythos. Google doesn't make it easy.
