It is insane from a consumer point of view. Luna is cheap and smart enough to do many agentic tasks. Cheap enough so that you can put it on a website without auth.
1. you can have luna clean up after itself and improve code 2. you might be doing something like video-editing, cad modeling, artistic direction, pcb routing, etc. that need to run a long time to "converge"
Has there ever been an instance in history when this strategy worked?
Plato argued that writing things down will make your memory worse, and less skilled as a debater (kind of true!)
How are the Luddites doing at textiles?
I remember the arguments that using 'high level languages' like C and Pascal will make you not understand machine specific details (kind of true!)
I respect that you want to learn how things are done, that is a great trait. But once you learn how its done, you should use the tools to free up cognitive load for more difficult tasks.
For me, long-running tasks are not about generating a lot of code. I’m very picky about what my code looks like. But I’ll happily run for long periods of time debugging problems and/or doing testing and validations. Depending on the problem space, this could mean hours of work for each iteration while it attempts to find a working solution
I don't see how anyone can be using Claude with prices like this, it's pretty incredible what the OpenAI team is doing, w.r.t model quality and pricing.
Prices per 1M tokens Claude Opus 5.5 Claude Opus 5
Cache reads $0.20 $0.50
Input tokens $4 $5
Output tokens $20 $25
Cache writes $5 $6.25
GPT-5.6-Sol, GPT-5.6-Terra, and GPT-5.6-Luna were released in July of 2026.
The first release from the GPT-6 series was GPT-6-Astra. GPT-6-Astra happened on around September 3, 2026, and the previously-mentioned GPT-5.6-* widgets remained available.
Today, September 22, 2026, we now also have GPT-6-Sol and GPT-6-Luna added into the mix.
As I write this, all of the model identifiers I've mentioned are available to select for use within Codex.
And why is that bad? As your brain gets older, it will not remain so clever, so you'll be grateful for an AI that thinks like you do when it comes to your line of work.
Nope, but I am old enough to recognize that my skills if not integrated by AI can ultimately be lost to the wind. And I am not talking about something that can be covered in a skill file or two. It is best captured by my work product itself. I am also wise enough to not be too selfish.
You're building your livelihood/workflows on a set of inputs that you have no idea what they actually cost or how reliable they'll be when the VC cash stops flowing. If you're OK with that, do your thing but it seems a little foolish to me.
In the event of a crash, the investors who put countless billions into this will be still be seeking to maximize their return. Even if it is just pennies on the dollar. Assets (including compute hardware) will be sold, just as they are also sold when any other business fails.
Or maybe a crash doesn't happen. Maybe prices rise to the moon instead and there's nothing we can do to lower them.
Or maybe (just maybe!) a crash never happens and there's never a huge price increase. Prices stay low-ish.
All of these possible outcomes suggest to me that the maximally-sane option that a user can select, today, is to burn it while it lasts. And then, if/when a crash or a massive price increase occurs, just adjust accordingly. (The rest of us will all be in that same boat, too.)
I would bet on hardware flooding the market. I bet the machines running in the data centers don't use traditional PCIe connectors and cards. Maybe somebody could pull the chips and put them on standardized PCIe cards, but that is not a given.
V100s are three generations behind current and missing many of the features that modern inference benefits from, but they are the cheapest way to get a 32GB gpu.
It seems silly to say we have no idea when we actually do, though. We know how much hardware costs, we know how to reliably run a webservice that hits an API hosted on a machine with a GPU, we know how to operate these things at scale outside of OpenAI and Anthropic (not Nvidia). VC money can be patient, Uber's profitable, yeah $1 Uber rides got us hooked and they're running the same playbook. Unfortunately the convenience is worth paying for, so it seems dumb to think we can control the beast or ignore it, or get everyone to agree to hold back.
Is there a world where OpenAI starts charging $2,000/month for what we previously were paying $20 for? What are we going to do? AWS could totally jack up the prices for EC2 instances as well, but we've come to rely on that as well.
Push comes to shove, OpenAI could go out of business tomorrow and I could pick up roughly where I left off for $25k, which is the cost to serve GLM 5.3 Flash on four Nvidia GB10s. Granted, if OpenAI et al go kaput all at the same time, I could probably get a whole lot more compute for a whole lot less money.
I'm fairly sure most open weight model providers are serving them at a sustainable price - and I've used them enough to know that I could live with them if the big boys did a rug pull.
Not that anthropic models are very good at this, but due to the changes in tokenizers and thinking tokens: cost per token is not as helpful anymore as cost / task.
As someone who has used Claude Code and Codex the prices don't matter in the same way but I found that I burned through my usage way faster on Codex even though I regularly hear that the Codex plans go further. That was not my experience and the intelligence was comparable to what I was getting in Claude.
If these price changes mean that coding plans have effectively more usage then that's great, but Codex is surviving on resets from my own experience using it. I was glad to go back to Claude.
I mainly use Codex/Sol to review my plans drafted by Fable. But beyond that, Astra blows through usage limits too fast to be a daily driver and writes weird code despite what my "house style" is, and Codex is behind Claude Code in terms of critical features like seeing what's going on in subagents.
The parent + subagent workflow has become critical for keeping the reasoning agent (parent) context-lean while also letting me chat to the main agent while work is getting done.
My main process is to use Fable to reason and then spawn Opus subagents, and I get amazing results, and I'm always looking into what the subagents are doing.
- A model (like other GPT ones) that hides thinking traces and thinking summaries, which infuriates me
I've been in the Claude camp for a while, but the way it writes has left me with a a brick for a brain and wanted to see if Astra was as good as they say. Well, I can't know, because in the time it takes for it to actually build anything useful, I've moved to other ideas.
Unbearably, annoyingly slow. I keep thinking I must be doing something wrong.
You're right, it's probably quite unfair of me to say it eats lots of tokens when I am paying double for claude than codex and complaining about tokens.
The rest still stands, though.
But if I've learned anything is that in a 2 months I might have completely turned around, who knows
The thing is that this thing is constantly compacting.... I get 1M context with Claude and ~256k with Astra. Even if the compaction loses much less information on OAI's side, it takes so long it's barely any use for me...
I've tried High and Max. They have produced decent results, but they're so slow.... I will try to lower it a bit and see the difference, but it's a delicate balance: I don't want to waste literal hours on the incorrect reasoning level to only then have to spend those hours and tokens to do it right.
At this very moment, Astra has been working for 1h15m on a task. At this rate I genuinely expect it to take about 10 hours. I feel like claude would do it in at least a third of that. Let's see if the quality justifies the slowness (it better)
The major difference being the 1M token context window. Once you exceed 272K input tokens, Codex Sol is roughly the same price as Opus; and Astra similar to Fable.
>I don't see how anyone can be using Claude with prices like this
One potential deciding point is that Claude still has a $200/mo 20x plan, where, since Sept 11, OpenAI does not and has no ETA for the return.
I downgraded my OpenAI plan 2 months ago to the $100/mo, but my usage has gone way up, but now I can no longer upgrade to the $200/mo plan ("This option is temporarily unavailable"). Thankfully I have 2 usage resets available, but I'll probably be switching back to Claude; I was super happy with Astra but I'm burning through tokens and have 4 days before my next reset.
Grok is offering a competitive product - not the absolute best but among the top three. They are doing for $2 and 6/mio. So maybe they see it as taking the economic opportunity while their model lags slightly behind. OpenAi follows. I can't say if their models are economically better or they are taking the loss but they can still pull it. SpaceXAI has an interesting path forward. They are not out.
What a day! I couldn't really use the last Luna for much (wasn't smart enough) or Astra (too expensive). So this release is really exciting. I can probably use Sol 6 as much as I want in the week, which as great.
I've found Astra to be horrible at making orchestration decisions. I will be trying to use Sol for both. Fable is very good at it though. Worst part of my week is when I hit my Fable usage limit and have to switch to Astra.
Thirteen comments in six minutes, primarily one liners about how "insane" and "very nice" the new prices are, and how "Claude can't compete"? Within one hour of the Opus 5.5 launch announcement?
Fundamentally I feel like coders just doesn't even need to be that smart anymore given AI assistance. This place ten years ago used to be filled with some of the most interesting comments/takes around for that reason.
I remember how a few months ago Dang was criticizing people for making comments like this. Guess he just realized how stupid that was and stopped bothering eventually.
Ya all these articles lately about how everyone is sick of reading AI prose, and interacting with models in general. Tons of new model optimizations and workflow optimizations or whatever. I'm not really aware of any idea or product aimed at making the internet usable, and making it somewhat resistant to the generated noise. I think HN is a bit better than reddit for this type of example for floods of comments, first movers on reddit REALLY rise to the top and stay there.
Are you trying to imply that nothing OpenAI can release would justify that response and therefore the people must be bots?
Asking cuz I don't think I'm a bot [pats self], I legitimately prefer the GPT models to Anthropic's, don't like Anthropic's customer service/reliability story at all, and I welcome a massive price reduction. Seems like something I should be happy to get.
If you'd told me I'd be typing this a year ago I'd be skeptical though.
It's asking a lot to trust they can or will maintain this new pricing. In any case it's exciting to think this might lead to further price cuts in the highly competent and competitive Chinese clones. I'm still using ChatGPT for interactive queries, but at this point pretty much only because of its familiar UI
Looking at their own charts it seems like it's only small incremental improvement over 5.6 Sol, but with a massive cost reduction. And the better writing/communication style that Astra had.

This will make me more valuable in the future when everyone has lost the ability to do anything on their own.

Do you mean 100% more expensive? GPT 6 is 100% more expensive than 5.6 per your post.

Highly subjective take
What kind of work do you do, out of curiosity
If they’re subsidizing my usage, that’s great.
In the event of a crash, the investors who put countless billions into this will be still be seeking to maximize their return. Even if it is just pennies on the dollar. Assets (including compute hardware) will be sold, just as they are also sold when any other business fails.

Unbearably, annoyingly slow. I keep thinking I must be doing something wrong.
However, it is not a 'token eating machine'. In fact it uses a third of the output tokens of Opus 5.5, Fable 5.1, or Opus 5.
17k for Astra xhigh vs 61-66k.
The rest still stands, though.

Did cache read/write also decrease by 50% or similar? That's where most (95%+) of the cost is for agentic coding workloads.
https://developers.openai.com/api/docs/pricing
Let's look at open-weights models with 3T size: https://inferencex.semianalysis.com/run/kimi-k3-on-b200
This suggests inference margins in the ballpark of 98% if we assume 5.6 Sol is about as efficient to serve as Kimi K3.
We don't know how much they are bleeding financially, it might just be a front
One potential deciding point is that Claude still has a $200/mo 20x plan, where, since Sept 11, OpenAI does not and has no ETA for the return.

Wierd!!
Astra is the best. Luna is cheapest then it seems like Sol is the middle child like Terra.
Goodbye Hacker News--it has been a good run.
