I don't have the words.

I genuinely thought we were in a stage where we were plateauing and going in for 5-10% improvements over months. Seeing spikes like this makes me question about where the floor really is.

Re:Advancing the price-performance frontier with GPT‑5.6 by jpadkins on Thursday July 30, 2026 @02:09PM (#49113557)
When model intelligence reliably hits 90%-95% of current day knowledge worker tasks, they are going to burn those weight to silicon and we will see another 10X improvement in price/performance frontier.

The dynamic GPU clusters will be used for the 5% of tasks, and pushing out the frontier. Also there will be a set of knowledge tasks that are not done today (because they are too difficult for most knowledge workers), that will start being done in the future.

Re:Advancing the price-performance frontier with GPT‑5.6 by jrflo on Thursday July 30, 2026 @02:30PM (#49113799)
Burning the weights into silicon would be many orders of magnitude increase, not just 10x. It's kind of crazy that this hockey stick the AI hype bros talk about seems more and more every day like it might be real

https://taalas.com/ has done it already for a wildly obsolete model. 14000 tokens per second.

https://chatjimmy.ai/ is their interactive. Tiny context, very dumb, but absurdly fast. Imagine this as a tool call for claude code for trivial changes - the tool call from the harness takes longer than the execution.

Speed is the metric I'm currently most interested in. The models are smart enough.

Once speed significantly increases I think we're going to see some interesting downstream effects. The three things I currently spend the most time waiting on are LLM API requests, Rust compile times, and nix derivations. As AI latency approaches zero I think we're going to start taking a hard look at whether slow-compiling languages are adding enough value over Golang, Typescript, or even dynamic languages to be worth the slowdown.

Re:Advancing the price-performance frontier with GPT‑5.6 by jaggederest on Thursday July 30, 2026 @08:26PM (#49117618)
Yeah. A model smarter than Fable by, say, 50 human IQ point equivalents, running in some kind of autoregressive process continously on whatever goals you put into the loop, on baked silicon, would be maybe my low end for the potential in the relatively near future.

The magic is in the fact that they essentially have an ASIC llm device. There is no other trickery. The problem they will face is that it is actually locked in silicon, so upgrading models will be difficult, and likely require new hardware each time.
Re:Advancing the price-performance frontier with GPT‑5.6 by ch4s3 on Thursday July 30, 2026 @09:03PM (#49117867)
At some point I imagine you’d add a software layer on top that holds more current training and can be called as needed trading off for slower responses. There’s already work out there splitting models across networks. You could have the base on silicon, some stuff in memory on the machine, and another frontier tool in the cloud.
Re:Advancing the price-performance frontier with GPT‑5.6 by jaggederest on Thursday July 30, 2026 @09:29PM (#49118027)
Taalas actually already support LoRA, basically doing exactly what you say.

The other thing that I think is really interesting about all of this, is that LLMs are already perforce behind the times with their knowledge cutoff, so adding an additional ~3 months for bake into silicon isn't such a huge deal, I think, for the ~10x more efficient and faster you get.

Fully interactive games where you can talk to every NPC by text or voice and have an LLM drive the story (with your own meta prompts to guide it, if you so wish). Maybe even have them generate assets on the fly too.

You can kind of get a sense by running these things at home - I'm currently running Laguna. One interesting thing is that per stream doesn't actually slow down that much with multiple concurrents, because the bottleneck remains the memory bandwidth until pretty significant request depths, and then eventually you hit the GPU's limits. It's one of the big forces that pushes for centralization in this stuff, the fixed costs to run one are huge, the marginal costs of additional tenants, relatively small.

Blocking Fable for sure made it very politicl a lot sooner than i expected it to happen.

and because China already has massive problems of getting access, they are pushing it on hardware too like what Huawai did without EUV.

It seems China is already able to do DUV a lot sooner than others expected.

That's the media and in particular US KOLs of all sorts driving the wrong impression of China and other places. China and many other places for example have fast public transport that the US doesn't and can't even imagine today. They're not behind.

China's DUV still isn't that production grade (mass produce-able) so don't get that hyped up the wrong way (in a different direction).

The whole China-is-behind with tech and in particular semi wasn't that they can't. The truth is they spent decades in internal politics and corruption. That all got solved with the bans, so thank the bans! Jensen even said the bans were bad.

Or, when we will start doing this, who's going to be able to do that in scale?

I'm seeing the TAALAS example, but it's only an 8B model, suggesting some real limitations parameter wise. And for 2.5kW?

Re:Advancing the price-performance frontier with GPT‑5.6 by adrianvi on Friday July 31, 2026 @04:38AM (#49120535)
I can't speak for all cases, but the AI space is seeing improvements month by month, so it is beneficial to wait until it settles (a model becomes the standard in intelligence/price) before designing and mass producing an "LLM ASIC" of said model.

The big AI labs won't do that unless they are forced to, as they want you to spend more money on the big, expensive, frontier models (so they can live up to their valuation), so it's more likely that you will see this on smaller open weights models.

Re:Advancing the price-performance frontier with GPT‑5.6 by jmb99 on Thursday July 30, 2026 @07:21PM (#49117095)
My uneducated guess says, not much. For running massive models you still need a ton of high-bandwidth interconnects between many individual chips/GPUs/etc since you need to do math across a few TB worth of weights. That's simply going to require more power (and more die area in I/O, and therefore more cost). Being able to run small models in tiny power envelopes is incredibly useful to people, but I believe it will be covering a different niche than what datacenters can provide. Likewise, you'll still need crazy amounts of high-end memory to populate whatever goes in these datacenters.

The only thing that will crash prices is reduced demand (duh) or, more interestingly, increased production. In particular, if CXMT is able to get their DR5 fabs up to a reasonably high yield, that could add some downward price pressure (as could government subsidies). As well, if Micron/Kingston/Hynix think that CXMT is going to start cutting into their market share, they might be willing to either increases supply or drop prices. Unfortunately CXMT looks to be taking quite a while to get their new fab up to max capacity so that may take a year+ before anything manifests.

If you're interested in following the (publicly available) info on these sorts of things, check out what companies like Axelera, DeepX, and MemoryX are doing today and have on their roadmaps, as well as the sorts of chips/SoCs Qualcomm, Kinara (now NXP), and Ambarella currently have announced (or have on the market). And remember, that pretty much all of these chips on the market today were in initial development more or less when ChatGPT first launched. If you knew what you knew today (or a year ago) about what requirements current- and next-generation models would have (from a silicon perspective), what might you do differently? Think for instance, host system interconnects, amount and speed of on-package or on-die memory, image/video decode capabilities, int8 vs fp8 vs fp16 vs bf16 compute units, etc. And, consider that most "AI" stuff in development a few years ago was all 15nm or 12nm - because who was gonna pay big money to get fab capacity at 3nm to run some object detection models? So most of the stuff on the market today is on very old nodes and therefore not super power efficient.

I wouldn't be surprised if they still had some margins since cheaper models are much harder to nail the accurate sizes off, and you still pay 2x for 1M context window.

But if this is even at 400B size it's insanity those inference prices, maybe 10-20% margins, if it's higher I would like to know is it their own chips or maybe they have accurately sized the model to fit on exactly a B300?

Could be a lot of magical things we can only speculate, but from here there likely isn't another 60-70% margin, like I have heard people claim, I would definitely be willing to bet on that.

Could still be a healthy 10-30% margin. Especially with Terra.

DeepSeek v4 Pro & MiMo v2.5 Pro (Opus 4.6 quality models for code) are insanely cheap for agent-driven work due to their super low cached-input prices ($0.0036/mtok) [0]. For Luna, the cached-input price drop isn't disclosed in TFA, but the pricing page puts it at $0.02/mtok, & that's 5x more expensive.

[0] I am constantly surprised how much work pay-as-you-go with DeepSeek / MiMo will get done. I've barely crossed $2 each in a month of use (~200m tokens).

Re:Advancing the price-performance frontier with GPT‑5.6 by computerex on Thursday July 30, 2026 @03:15PM (#49114385)
Absolutely. Although DeepSeek started announcing "Peak valley" pricing which started making me nervous. I have spent $50 usd in July on deepseek and for that much spend I got SO MUCH mileage.

I feel perfectly content in using pay as you go pricing with deepseek. On the other hand, although Anthropic's models used to be my bread and butter for personal work, they are simply too expensive to reach for these days.

Re:Advancing the price-performance frontier with GPT‑5.6 by ismailmaj on Thursday July 30, 2026 @01:52PM (#49113341)
it's 80% less cost, not 80% in efficiency gains, could be that Luna was overpriced to begin with, we don't have much info on the models themselves.

Assuming the efficiency gains are real, I feel like something has to give, maybe worse quality due to aggressive quantization/kv cache compression?

Re:Advancing the price-performance frontier with GPT‑5.6 by heisgone on Thursday July 30, 2026 @02:24PM (#49113727)
Let's suppose each models was subsidized at 70%, so that we only pay 30% of the cost. They would loose much more money per token on the more powerful models. It's in their interest to encourage the use of the less expensive models. Let's say they increase Luna subsidies at 90%. They would still "save" relative to the use of the more expensive models.

Not true at all. Do you really believe that generating 1m output tokens on sol really cost 100 usd?

These companies are printing money on inference. The only issue is the capex of expending on new servers but they are generating TONS of income.

High-performing open weight models being released recently, and your customers looking into working with multiple providers as a result, are a great reason to drop prices on your non-frontier offerings.

Although I'm sure there are some efficiency gains, the technology is too new and labs are scrambling to release too quickly to think that the low-hanging optimization fruit has been picked already.

If you use Codex it's different, the harness has a lot to do with it and there's definitely been changes including recently.

But yeah I do'nt want to know what Kimi 3 is pushing buttons inside Anthropic, OpenAI and Google.

Besides any floor: For every year the tokens get faster and cheaper, we will see new things like properly working AI factories which mimic expert teams. A lot more parallism as well.

MI500 series is supposedly already taping out and they're claiming massive increases (we'll find out end of 2027 prob).

Luna is an extremely strong model.

> Luna is an extremely strong model.

By benchmarks, which sadly is a poor measure. Yes Luna is a good model under certain circumstances. Whether it is great for general usage is another story. Sonnet is definitely better when prompts are more vague and it needs to decide things. Luna generally sticks to things very strictly and goes off in bad ways.

Re:Advancing the price-performance frontier with GPT‑5.6 by mediaman on Thursday July 30, 2026 @02:34PM (#49113843)
Yes but there is a big, big market for subagents to consume lots of tokens cheaply and condense information up to parent agents. Luna would not be my choice for planning. But an explorer to comb through a codebase to find relevant parts? Or for enterprise retrieval, where it needs to search across many different types of data to see where to focus efforts for a smarter model? Or to wake up periodically to evaluate some conditions and determine if a bigger model should be spun up? Definitely.

I've previously found flash (for all the hate it gets) to be good for these kinds of things. Haiku was fine but it's ancient.

That's again not some "intelligence factor" here. Different agents work for different use cases. Luna wins some. Terra wins some. Sonnet wins some. Flash was really good at exploring.

So I'm not sure what your point is? There's a big market for everything. Even within the market you describe it's likely not a Luna-size fits all either.

Re:Advancing the price-performance frontier with GPT‑5.6 by Klathmon on Thursday July 30, 2026 @08:16PM (#49117557)
I'm actually finding Luna to be an extremely strong model in practice.

I almost exclusively use it with xhigh or max effort, but when run like that it's been an incredibly cheap little workhorse for most development work. I'm still leaning on Sol for planning and debugging, but when it's time to start pumping out code I've been leaning into Luna (Max) and I've been enjoying it! And that was before the price drop, it's going to feel practically free at this point

Re:Advancing the price-performance frontier with GPT‑5.6 by jug on Thursday July 30, 2026 @08:51PM (#49117793)
Yes, I've seen this too and how Luna xhigh is so good that Terra doesn't really serve a purpose because beyond that you can continue at Sol medium. This can be the most cost efficient way, and especially now!

Sonnet and Haiku were already in an awkward spot, likely by design.

Anthropic's big marketing push this year has been entirely focused on getting people to use Opus via a Claude Code subscription, to the point that Sonnet is almost viewed as the poor man's alternative, and from what I've seen, almost nobody uses it.

Actually, here's an interesting project for all the vibe coders looking for their next front page post: scrape a ton of commits from GitHub with Co-Authored-By: Claude and figure out what the percentage split between Opus/Fable/Sonnet is. I'm willing to bet it's less than 10% Sonnet.

This may be misleading, since I suspect many are using a blend through sub-agents. I tend to bias for Fable to orchestrate and Opus for implementation via sub-agents.

Opus 5 is not strong enough as the top-of-stack model, and feels idiotic after a week or two of heavy Fable usage, to the point where I'm paying for Usage Credits to keep using Fable rather than having to slum it with Opus.

We are not purely rational creatures, thank God. Sometimes those "limiting factors" you listed -- stress, peer pressure, hormones -- are crucial elements of informing the problem solving process and arriving at a decision or a solution that actually works.

All an LLM can do is fulfill a prompt, no matter how misguided, backwards, or incomplete that prompt actually was.

Luna had a price hike vs mini (its previous replacement). The cut now just puts it back in that ball park.

Had to ctrl+f for someone saying this.

I typically do lots of mini calls for research (100s of millions or something in that ball park). Newer models made that absolutely impossible, and the fact that the older ones are starting to get deprecated made me switch to e.g. deepseek for some of my runs. We'll see if I move back after this.

I don't see how this follows. The cost of nails has fallen by 95% over the last century. It's because the cost of manufacturing has fallen. Not because they are selling the information of nail consumers.

Tokens are not normal software, because they have marginal cost, and I think people who are used to software economics really struggle with this. With token generation there really can be manufacturing cost efficiencies where one producer is just straight up better at serving product at a lower marginal cost.

> The cost of nails has fallen by 95% over the last century

No it hasn't!

A century ago, some nails cost 2.5% of disposable income, and now the same nails cost 2.3% - only a little cheaper.

The cost of nails has remained remarkably consistent for a century. The problem is that you have ignored the depreciation of money.

Let's assume California prices and income and pick a bigger retail package of nails as you might use for building a house. The numbers used to calculate percentages: in 1926 a 50lb keg of 4" nails was $2.75 and median after tax income might be $108 per month. In 2026 a 50lb carton of 4" nails is $106 and income might be $4,516. Albeit I assume nails are now more readily available and the quality of nails is likely better; and perhaps I should have compared galvinised nail prices.

sama literally just said they wish they had bought more. the price drops are almost certainly due to good old fashioned hardware innovation (wafer scale with cerebras) and optimizing hardware development based on model architecture and inference costs. other inference providers will try to do the same if they can.

Re:Advancing the price-performance frontier with GPT‑5.6 by SwellJoe on Thursday July 30, 2026 @06:55PM (#49116894)
I think there's a ton of room for efficiency improvements in how the models are built and run, and I think OpenAI has both prioritized that work and figured out a lot of the tactics (and borrowed some from the Chinese models like DeepSeek and Kimi, which have published a lot of their research and tactics for running big models fast on minimal hardware).

I think there's also a new generation of hardware in the past year or so tuned specifically for LLM workloads, where it was almost an accident that GPUs worked to run LLMs before. So, while there's still this ridiculous shortage of hardware, what is being delivered is much faster and cheaper to run for these specific workloads.

I wasn't expecting it to happen from the US vendors, though, as they've spent so much capital to get to where they are they need to make huge margins on inference to pay it all back. I expected the Chinese models who're running much leaner operations to be the "frontier" on costs (and they have been). But, I'm glad to see OpenAI joining the "cheap and cheerful" models party. There's a lot of work in that area of capability. Probably most work people are doing falls into that area of capability.

Re:Advancing the price-performance frontier with GPT‑5.6 by onlyrealcuzzo on Thursday July 30, 2026 @07:58PM (#49117410)
Prices have consistently gone down 90% every 18 months like clockwork for about 5 years for the same level of quality. There is no end in sight for at least another generation.

There is ZERO reason to believe models 1/10th the size of frontier are completely capped on intelligence and impossible to get smarter.

They have consistently compressed the intelligence of larger models.

You'll see it first on the small end, when the stop being able to compress intelligence, you know that will slowly bubble up and up the chain to larger and larger models.

There's no evidence we've reached that at the bottom.
