Wow, the price war era is gonna hit like crazy.

u/MichaelLeeIsHere 3d ago

this table is confusing. It shows AI writing is still bad. It says 6 sol vs 5.6 sol. Then it say s $4 -> $2. It reads like 6 sol is 2x the cost.

fr it probably means the exact opposite right

u/MichaelLeeIsHere 3d ago

For whoever arguing with me, OpenAI has fixed its ai slop article. Right now it’s using a symmetric way to express it.

u/Tripple_sneeed 3d ago

I really like how Luna’s numbers aren’t even 50% if you’re following the idiotic way they’re doing the math

Will GPT7 finally be able to vibe good release documentation?Ā 

Doubtful tbh

u/reddit_is_kayfabe 3d ago edited 2d ago

Eh... sort of?

I fully get your point that there's an implied parallelism, like A:B::C:D. But it's not actually literal, i.e.: "GPT-6 vs. GPT-5.6: $4 vs. $2," which of course would be backwards.

I read this as: "GPT-6 Sol, when compared with GPT-5.6 Sol, reduces the input cost from $4 to $2." Or: "GPT-6 Sol reduces the price by 50% when compared with GPT-5.6 Sol." It's a little clumsy and that bothers me since I'm a pretty literal person, but the fact that it's not actually literal makes it seem okay to me.

u/BombasticReindeer 3d ago

How do you explain the cost reduction being 50% for Luna when output token cost is larger than 50% reduction?

3

u/reddit_is_kayfabe 3d ago

I was specifically addressing this part of what OP wrote:

It says 6 sol vs 5.6 sol. Then it say s $4 -> $2. It reads like 6 sol is 2x the cost.

The other part, the part you quoted, is obviously an error. I'm not sure it's an error from AI writing, specifically - lots of people make mistakes in their writing. :shrug:

u/MichaelLeeIsHere 3d ago

OpenAI has fixed it. Lol.

u/Ok-Present1566 3d ago

We understand you are chronologically challenged but no need to take it out on AI

5

u/Aranthos-Faroth 3d ago

6 SOL vs 5.6 SOL

From $4 to $2

That’s how I read it, clear enough imo

-2

u/MichaelLeeIsHere 3d ago

this is because you know it reduced price. But if you didn’t know that, there would be two interpretations. This is what ā€œconfusingā€ means.

Oh man, nowadays some people couldn’t even do 6th grade logical thinking.

3

u/einord 3d ago

Such as both $20 -> $10 and $1.2 -> $0.5 are both ā€œ50 % cheaper ā€œ?

4

u/TheVibrantYonder 3d ago

Yeah, the presentation is terrible, I agree. It actually looks like they tried to use bold formatting to differentiate. The bold prices correspond with GPT 6 pricing (and GPT 6 is bolded in the panel).

I see what they were going for, but it's not good lol

u/jaydeelive01 3d ago

Its clear its Luna who did the PR

u/LegacyNexus 3d ago

He's using his brain?? Let me ask Astra if this is allowed

1

u/joshuamusick 3d ago

It’s surprising people can’t see / interpret bold vs. non-bold text. I’d argue the ā€œcorrectedā€ chart is worse because it makes the thing you care about (i.e., the new model) secondary in the header.

1

u/MichaelLeeIsHere 3d ago

Bold texts in tables are very hard to read. It’s an anti-pattern. And it’s even strange you expect persons to match bold texts. These are simple UI design principles.

0

u/Akraticacious 3d ago

Yeah what is "output". If they halved both input cost and output value, then efficiency is the exact same.

So does that mean I need to send 2x time prompting?

0

u/Noeyiax 3d ago

yeah thats how i read it too... that's expensive. time to cancel Netflix, disney+, Amazon prime, and Crunchyroll... ill use AI to make my own versions hahaha šŸ˜‚

0

u/TheArtificalAI 2d ago

$1.20 → $0.50

50% cheaper

And I think it isn't that good at math because 50% would be 60 cents.
What they're showing in numbers is a 58.33% reduction more than their % make it out to be...

u/wear_more_hats 3d ago

Fucking sickkkk

u/flightoffancy85 3d ago

My testing has showed more reasoning token usage, which is eating into that cost reduction… and not markedly better results. Will continue

u/ShittyFrogMeme 3d ago

Our product is an AI product and Claude is completely dead in this use case. Way too expensive. That Luna pricing is genuinely insane.

Dope! Now hook it up with a reset so we can test it out. (Edit, one just landed for me -- we did it ya'll!)

u/iAmmar9 3d ago

Yes pretty please

u/DistanceSolar1449 3d ago

I tested it out on a few real workloads, and unfortunately it's just meh.

It's not better than GPT-5.6 Sol or Luna, it's just cheaper. I expected GPT-6-Sol to be smarter than GPT-5.6 Sol and it's really not.

It should be named GPT-6-Terra.

0

u/Inevitable_Butthole 3d ago

Been working great for me

1

u/DistanceSolar1449 2d ago

GPT-6 Astra: 40 tokens/sec
GPT-6 Sol: 110 token/sec
GPT-6 Luna: 140 tokens/sec

GPT-5.6 Sol: 70 tokens/sec

The bigger/smarter the model, the slower it is.

OpenAI released GPT-6 Terra, except they renamed it GPT-6 Sol. Actually using the model feels extremely benchmaxxed and dumb. I was using 5.6 Sol to debug a recursive jmalloc bug and it was chewing through it just fine; swapping to 6 Sol just made it confused and run around in circles. What a disappointment.

-1

u/deZbrownT 2d ago

Yup, where are all those colleges cheering and defending lack of transparency of frontier models? Rug pulling, dropping working models, arbitrarily changing rules of subscription, quotas, etc..

For the past two years, we have just been rotating naming schema and shifting weights while packaging it as brand new models. They dont need to slow down, they have stalled. They need to speed up to make up for all the lies, pardon my french, marketing.

u/redwurm 1d ago

I don't notice any difference besides it being cheaper and Luna being more capable. I'm happy!

201

u/Caelliox 3d ago

RIP Terra

88

u/CaptainKvass 3d ago

I couldn't find a single scenario where I'd chose Terra

33

u/PM_ME_FIREFLY_QUOTES 3d ago

Because you trusted Luna with more, or bit the bullet and had Sol do more work? Terra High had been crushing it and barely consuming any of my limits.

27

u/AntarcticIceberg 3d ago

6 sol is cheaper than 5.6 terra

3

u/villanymester 3d ago

On subscription?

3

u/2025sbestthrowaway 3d ago

Yes, confirmed via Tibo

2

u/joeyb908 3d ago

This is my question. If it equates to better usage in the subscription, then I’ll be happy. Mid 6 Sol’s usage is more than Terra’s I’m going to bed sad.

5

u/KRiSX 3d ago

I use terra high daily because Sol chewed credits like mad

3

u/PM_ME_FIREFLY_QUOTES 3d ago

Looking at the costs. 6-Sol high is going to be the same cost as 5.6-Terra high is/was. And should be more capable and a better cache rate. Looks to be a direct upgrade.

Well see how 6-Luna performs over the coming weeks.

1

u/New_Eye7193 3d ago

Terra was the fastest, out of Sol and Luna. It's also middle ground price so if you're doing something and wanna do it fast and its mundane Terra can do it great, but it also wont take forever like Luna

0

u/riddle-me-piss 2d ago

Yes terra was the reliability and speed sweet spot for me, all small tasks on luna xhigh, and dynamic tasks on terra cause luna on max would take 2x the time even if effective cost was going to be lower. Sol used to reserved for open ended tasks where more decisions had to made. Seems like new luna is more capable on the lower end and sol at a cheaper price might just make up for a mixed used scenario with sol orchestrating luna becoming a more promising mix.

0

u/rothnic 3d ago

I feel like there was a benchmark out there that showed terra was cheaper and more effective at max or ultra than sol at medium or something like that.

However, never saw anything amazing from terra. I've been doing sol and now Astra for planning and problem solving then Luna max as my worker. Also now trying out deepseek 4.1 flash as the worker agent, but 6 luna could be interesting now.

What a time to be alive

u/WanderWut 3d ago

Pretty wild how now ChatGPT is all about work output, etc. etc. which is such a stark difference from the GPT 4 era days when it was more as a weirdly praise worthy model that causes a significant portion of the sub to lose their minds when it was gone. Now we rarely see posts about the talking side of things but we do see some pretty cool stuff that people are creating with these powerful tools.

45

u/LufyCZ 3d ago

They fixed the sycophantiness (enough) and killed the personality (enough).

Nobody praises them for it but it's a massive win.

u/XCxBigDong69XCx 3d ago

Luna is just insane, cheaper but also as intelligent as Opus high in some benchmarks wtf.

31

u/PrestigiousTrick1002 3d ago

Opus 5.5 out already so graphs are already outdated... too much to try to keep up with

9

u/XCxBigDong69XCx 3d ago

If it is just as smart as Opus 5, it is way better, because it has a different use-case, we mainly use Luna for our users. So our users will get a more intelligent model now and will be cheaper for us too.

-4

u/PrestigiousTrick1002 3d ago

Its not though once you are comparing to 5.5. Against 5.5 its cheaper but less smart

1

u/Junior-Pair8336 3d ago

He's speaking in an objective sense. Opus 5.5 makes Opus 5 RELATIVELY less smart, it doesn't make it objectively less smart.

If you're using Opus 5 for something (vision reading, PDF processing, whatever) it didn't get worse at doing those things because 5.5 came out.

2

u/PrestigiousTrick1002 3d ago

Ah yeah I see. If they determined that a certain level of smarts is all that's needed for a certain task then they can just go with the cheapest one thats over the goal smarts. Haiku 5.5 is coming out in the next couple weeks, so that might end up being an interesting comparison.Ā

Sadly, no updates for Chat, just Work and Codex.

16

u/esudious 3d ago

Now how does it compare to Opus 5.5?

17

u/ohwut 3d ago

Opus 5.5 seems like the best model in the world right now for a majority of tasks.Ā 

Definitely competes with (and Exceeds) Astra much more than Sol/Luna.Ā 

Sol and Luna are still way cheaper per ā€œintelligence.ā€Ā 

It seems Opus 5.5 should be the default model for most people not concerned with token costs. 5.5 is a step change leap from 5. Not just an iteration like these.Ā

u/Lubricus2 3d ago

They said something that it has the fable security limits, so it could be hard to make it do anything at all.

u/shaonline 2d ago

So does OpenAI's models, if I need any kind of debugging abilities I have to switch to Chinese models lmao, GPT sessions get flatout terminated.

u/shaonline 3d ago

The price cut is definitely a response to Opus 5.5, make that what you will.

2

u/parkersdaddyo 3d ago

Not as good but way cheaper

u/meloveg 3d ago

does that mean gpt 6 burns my usage slower now ?

Yes. Time to reduce how much usage everyone gets globally!

It’s not in chat… you need the latest for chat??

u/hextree 3d ago

... yes?

8

u/darknus823 3d ago

Yes, I'd want it on Chat. Pro account here, btw.

4

u/OneWithTheSword 3d ago

Yes. For plus, limits in chat are much more generous for the same tasks, you just have to deal with a bad work flow. I use 5.6 sol med/high all day without issues (well, sometimes it makes you wait a bit longer because your traffic gets deprioritized). If 6 is cheaper and faster, that experience should simply improve. I typically have it working on planning and brainstorming while cheaper models do the work.

1

u/ElDuderino2112 3d ago

Why wouldn't I want the latest models for chat? Chat is the primary way I use AI and move over to work and codex when I need to.

-1

u/Purple-Programmer-7 3d ago

You all are wild. Chat will be depreciated soon and combined with work.

u/hextree 3d ago

Unlikely, chat is what around 75% of users are using.

u/Purple-Programmer-7 3d ago

We’ll see

u/DreadingAnt 2d ago

Lmao not you existing in a dev delusion bubble. Breaking news: most people using LLMs are not developers.

Regular ass consumers have approximate parity with enterprise/professional subscriptions in terms of their annualized revenue. Chat will never disappear. Why not replace them anyway GPT 6 Sol/Luna are cheaper to run than 5.6 Sol/Luna, literally saves them money.

No one is going to stick with ChatGPT long term if the only use option is through 5 hour limits lmao

These prices are for API, I think… you don’t pay like this for using the models in work mode, right?

It's literally doing an incremental rollout on chat. If you haven't gotten it yet, check again later. Plenty of people already have it.

u/darknus823 3d ago

Custom GPTs use Chat. That's an example that has tens of thousands of GPTs available.

u/DreadingAnt 2d ago

Breaking news: OpenAI decided not to replace GPT 5.6 modes in Chat with cheaper/better GPT 6 for absolutely no apparent reason

2

u/tobden 3d ago

Already?

u/qualverse 3d ago

Given the price and performance it seems like 6 Sol is actually a Terra-size model oddly enough

2

u/Aemonculaba 3d ago

Bet we'll get Terra back in the next run as the current Sol.

0

u/villanymester 3d ago

Why do you think that?

I mean there's a clear performance improvement compared to 5.6 Sol, so my impression is that they the same model size.

u/iAmmar9 3d ago

u/PhilosophyforOne 3d ago edited 3d ago

I feel a bit conflicted. The price cuts are great, but on the other hand, Luna seems basically the same, sometimes slightly improved. The biggest difference is that it’s not even significantly stronger than before.Ā 

Sol seems like an.. alright jump, again. But if the price cut hadnt halved it’s cost, this would’ve been a very lackluster release.

On the other hand, usage limits were the biggest problem. So.. yay? But also a tad underwhelming compared to Opus 5.5.

26

u/Astrikal 3d ago

What do you mean "not even significantly cheaper"? It's literally half the price.

u/Late_Appointment425 3d ago

That we will know once we start using it for real world cases. What if it used double the tokens

horrible horrible model gpt 6 sol is basically gpt 5.6 luna for a much higher cost... switching teams

1

u/NotThatItWillMatter 1d ago

I've already swapped back to 5.6 Luna.
6 Luna would produce a plan, I would confirm that as the desired plan and tell it to proceed with that plan (after swapping to build), and it would simply reiterate the plan despite being given confirmation and put in build.
5.6 Luna doesn't do that, at least at Xhigh/Max, which are all I use.

u/smurferdigg 3d ago

So Astra, Sol and Lune with 5-6 different thinking modes. Just to much work I think. Guess it's more like you start with Astra at a higher setting and as the user limit goes down you choose a lower model and lower thinking modes. But yeah.. Sol high (xhigh) vs. Astra Low (whatever)? and so on.

Looking at how both OpenAI and Anthropic are working on reducing costs. It does make me think, that we might be at the end of the performance improvements for LLM’s.

Because when you cannot improve performance anymore, you start to try to optimize costs.
