I hope to see something like this, but in a small form factor like the NVIDIA spark.

I want a super fast LLM that is Opus 4.6+, like, in ability.

wmf11• 28 days ago

Memory bandwidth is the bottleneck in the Spark. If you replace the SoC with an optimized ASIC but keep the same 256-bit LPDDR5 the performance will be the same. You can increase performance by using wider memory but that's also more expensive.

phonon• 28 days ago

M3 Ultra has a 1024 bit memory bus (819 GB/s) and starts at $3,999 (96GB of RAM). It can be done....

a_conservative2• 28 days ago

I recently put 2+2 together.

Broadcom has become wealthy by being Google's TPU hardware partner, including sharing their TSMC capacity with Google, and evidently now they are doing the same thing with OpenAI. What a brilliant way to take advantage of the AI gold rush!

I wish they weren't using their piles of money to extort money out of the software industry like they are with VMWare and Bitnami.

alephnerd2• 28 days ago

Broadcom has become wealthy by being Google's TPU hardware partner...

Kinda, but not exactly.

Broadcom cornered the enterprise infra and security market in the late 2010s and early 2020s after acquiring CA Technologies, BMC (EDIT: Did NOT acquire them, they were considering it back in 2018 but decided against it and KKR ended up acquiring them), Symantec (which they bought instead of BMC), and VMWare and were able to make a strong cybersecurity story during the late 2010s cybersecurity and SaaS boom.

That gave them plenty of cashflow that helped subsidize their hardware business when hardware was not viewed as hot as it is today.

Additionally, Broadcom is GCP's marquee customer and has been for a little under a decade so they were able to make a sweetheart deal where all that software businesses at Broadcom would be exclusively using GCP and in return GCP would working with Broadcom to design it's silicon and source infra needed for their DC buildouts.

Ironically, the DoJ blocking Broadcom's acquisition of Qualcomm was the best thing it ever could have done for Broadcom, because it gave Broadcom the dry powder to dominate the Enterprise SaaS and build a strong niche in the cybersecurity space.

piles of money to extort money out of the software industry

From personal experience, executives and leadership who started off in the electronics and hardware industry are much more vicious and cutthroat than their peers who started in software.

Working in an industry that historically had to deal with high commodification, low margins, and long tail sales leads to leadership that can execute. Additionally, no one climbs the leadership ladder without having spent years as a line-level engineer, but that's true for software as well to an extent.

Edit: can't reply

Did they acquire also BMC?

Nope.

Broadcom was considering acquiring them in 2018 but decided not to go through with the opportunity and KKR jumped in.

kccqzy4• 28 days ago

Well Google has reduced reliance on Broadcom already. They found a new hardware partner, MediaTek, that’s probably much, much cheaper than Broadcom.

https://finance.yahoo.com/sectors/technology/articles/broadc...

HarHarVeryFunny5• 28 days ago

I just read a claim on Twitter that the reason these companies (Google and Amazon as well as OpenAI) are using Broadcom isn't just for design expertise, but because Broadcom have allocation agreements in place with TSMC and the memory manufacturers.

alephnerd2• 28 days ago

Most design partners have allocation agreements. The thing is Broadcom is an absolute GIANT in the ASIC design space, and it's closest competitor Marvell is a fraction of it's size.

There are a lot of large tech companies that most of HN has never heard about that completely dominate entire segments.

ahartmetz2• 28 days ago

...and because most hardware sales except AI accelerators are down due to RAM prices, Broadcom probably can't otherwise use their allocation at TSMC.

maz1b• 28 days ago

Pretty huge move. Google and their TPUs are looking infinitely more prescient as I think they are on their 7th generation, along with the offshoots it inspired like the LPU and even others, perhaps like Cerebras and their Wafer Scale Engine.

However, based off first impressions, it seems like this is meant for inference side, and not training, which is also an interesting choice.

forrestthewoods2• 28 days ago

Inference costs are higher than training now. I think.

Nvidia is king of general purpose training chips. But inferences can be specialized.

lugu2• 28 days ago

What makes you think this? With wider adoption the ratio shall shift in favor of inference. And API price is becoming more important than SOTA capability.

skeledrew2• 28 days ago

Training is pretty much a 1x cost, and efficiency there is already on the way down with architectural improvements. Inference though is an ongoing cost which over time takes orders of magnitude more resources, so focusing on making that far more efficient means way greater gains over time.

zer00eyz• 28 days ago

early testing shows that Jalapeño will deliver performance per watt substantially better than current state-of-the-art

We're starting to see what really matters here, and though this is hand wavy the TPU makes similar claims.

I think googles memo about having no moat still stands (see: https://newsletter.semianalysis.com/p/google-we-have-no-moat... if you are unaware). It kind of makes sense that all of this is looking more like 60's to 90's IBM, DEC, Cray, Sun and the hardware race that happened then. History doesn't repeat but it often rhymes and I suspect that these efforts will follow the same trajectory.

granzymes• 28 days ago

To be clear, that is not "Google's memo". It's a memo by a guy who happened to work at Google. There is a diversity of opinions at a company that employs 180,000 people.

cactusplant73742• 28 days ago

Cerebras's Codex Spark 5.3 has been a huge flop. Small context window and old model. But hopefully they can improve so that we can benefit from 1000 tokens/second with GPT 5.5.

ggcr• 28 days ago

With Reinforcement Learning, inference is very present in post-training stages now too

jerojero• 28 days ago

One thing I don't like about California based companies is how cringe the names always are.

"Jalapeño" is such a bad name, having an "ñ" already makes it difficult and annoying to deal with in so many little ways. Good luck with that.

But also, theres the sort of "yes lets use Mexican related things because we're California" thought that I just really hate. I don't know, its like corporate Memphis to me. You see a product like this, you know it's an uppity califonia based firm that came up with it.

dadoum• 28 days ago

May we scale smoothly, exponentially and uneventfully through A[SI]

That sentence sounds weird to me. I can't really put my finger on why, maybe the combination of adverbs, or just the fact of writing the desire of scaling as a company so directly. It feels (to me) like openly claiming their selfish goals. Or maybe I am just misinterpreting and they are referring to the whole humanity as "We" (but knowing Broadcom and in a lesser extent OpenAI doings, I am not convinced).

qsxfthnkp23222• 28 days ago

aw shucks nvda has some spicy competition

Make sure you all use that fancy ñ

boarush• 28 days ago

They don't have true competition, what they lose out on is market share with hyperscalers, since OpenAI would have no plans to share inference hardware with any other company right now. Plus, I don't know how does NVIDIA's investment equation pans out long terms given OpenAI will be investing in more purpose built inference stack for the future.

ismailmaj• 28 days ago

they're still kings for training, though I've heard Anthropic is training now on JAX+TPU setup, so might not be a monopoly in that segment.

Legend2440• 28 days ago

The only surprising thing about this is that they didn't do it three years ago.

satvikpendem• 28 days ago

I'm assuming they used LLMs to (help humans) do custom circuit design. Even pre LLM there were various computer optimizations that didn't require humans like genetic algorithms. It'd be cool to see a paper on how they did it.

jabedude• 28 days ago

how much does this chip help with inference speed?

wmf11• 28 days ago

It's probably the same speed but cheaper.

gravypod• 28 days ago

I wonder how close OpenAI is getting to using the memory they purchased. Are they planning to stack a huge amount of HBM2 into these chips?

wmf11• 28 days ago

I assume OpenAI has been buying memory and "giving" it to Nvidia in exchange for a discount.

v5v3• 28 days ago

designed for initial deployment by the end of 2026 and expanding in the years ahead,

So after the IPO and will be featured heavily in the IPO sales brochure as a future promise?

estetlinus• 28 days ago

Yeah, the narrative feels like pre-IPO shenanigans, and it looks like the lid on my laundry basket. I wouldn’t be surprised if this is a con.

Culonavirus• 28 days ago

Con or not it is an obvious thing they have to do. Might as well promise.

IIRC their biggest cost they're "hiding" in their financials by doing creative accounting is inference (putting it into marketing and whatnot, in the billions)... if they can't hide it in their S-1 then they have to rationalize it, either by a) increasing the prices (not gonna happen, with token based billing orgs are already watching their codex spends) or b) lowering the inference costs. You can lower that by "soft optimizing" (dumbing down) your models but then you have the other players breathing down your neck (see quick rise of Claude), or actually optimizing, in software and in hardware. We're like 5 years into the rise of LLMs, there's not THAT much left on the table unless you write to the metal you specifically designed for your models (and I'm pretty sure the lack of "nvidia tax" would help with covering most of the r&d costs of a custom solution, at least in the long term).

50% cheaper inference without losses in fidelity would unquestionably be a massive win for OpenAI.

fennecbutt• 28 days ago

I mean I'd love to be able to buy something like the 17k tps taalas chip as a pcie or m.2.

Imagine when we can roar along at that speed, low power. Can just have the model reason for a while about anything and everything. It reminds me of the "race to idle" for mcus etc.

MichaelNolan• 28 days ago

The current taalas chip is for a 3.1B param model. I’m hope so much that they can get that up to the 30B range. Just imagine Gemma 4 or Qwen 3.6 at 17k tps.

coder5435• 28 days ago

Taalas' first chip is for a Llama 3.1 8B quant, not a 3.1B parameter model, to clarify.

ipdashc4• 28 days ago

17k tps taalas chip

It's odd to me that I haven't heard anything about this approach (baking LLMs/weights into silicon directly) since. It seems almost common-sense that we're going to end up there eventually. And it feels like that point is drawing ever closer now that model capabilities, if not quite plateauing out, are at least getting to a "good enough" point for a LOT of use cases.

I wonder if it's being worked on in secret, if there's something about it that makes it infeasible, or if companies are really too nervous to lock in one model like that because the next one down the line could be a huge improvement. Re. infeasability, I have heard that the Taalas demonstration chip ran Llama 3.1 8B (a pretty horrible model) and that even that took a massive amount of transistors / die area. So it might just be the case that the good models are too big to fit on silicon?

wmf11• 28 days ago

Good models will require multiple Taalas chips but Groq and Cerebras also require a lot of chips and that hasn't stopped them.

topspin• 28 days ago

I have also been thinking about this a lot, and share your belief that this is inevitable.

Taalas has a running demo here: https://chatjimmy.ai/

It's eye opening: generated an AVX-512 optimized Mersenne Twister in C in 0.076s, 13,706 tok/s. Too fast for the tok/s to be terribly accurate.

mdp202118• 28 days ago

It's odd to me that I haven't heard anything about this approach ... I wonder if it's being worked on in secret, if there's something about it that makes it infeasible

The studies and efforts are ongoing and public, and there are technical hurdles to be faced - but the relevant works go back in time quite a lot and there is heightened interest in it now.

It seems that you simply took the "hyped headlines" for the whole of the work.

coder5435• 28 days ago

It's odd to me that I haven't heard anything about this approach since.

It has only been four months since they unveiled their first prototype. I don't understand your confusion. Chip development does not happen overnight...?

Their initial blog post laid out a roadmap, so theoretically they should have another thing to demonstrate this summer.

theowaway213456• 28 days ago

This seems like more competition for Cerebras? Am I understanding correctly?

HarHarVeryFunny5• 28 days ago

This is just an uncut wafer - I don't think it's intended to be a wafer-scale chip.

Cerebras etch memory onto the wafer alongside the processing elements, but AFAIK OpenAI are going to be using HBM memory and a conventional chiplet design.

KeplerBoy3• 28 days ago

Still competition for cerebras. Seems quite unlikely they will get an OpenAI deal anytime soon.

I call BS. It’s probably a white label around existing Broadcom IP, impossible to go from zero to this kind of chip in nine months. I doubt OpenAI had any significant contribution.

zerohp• 28 days ago

That’s exactly what this is.

9 months to production is completely impossible anyway.

9 months from design to early samples is probably impossible given than TSMC takes 3 months after tape out to produce them. Then it’s up to the customer to qualify and revise for production. TSMC doesn’t do that.

There’s no AI that makes this happen in 9 months.

bogdiyan• 28 days ago

I am not sure how much of the work is done by OpenAI, or whether it is basically a Broadcom chip specifically built for OpenAI models. It is a necessary step, but building a high-performance chip is not easy. Look at companies like Groq, Amazon, and Google.

u1hcw9nx2• 28 days ago

Both Google and Amazon also codesign heavily with Broadcomm (Amazon also with Marvell and Alchip)

Broadcomm does stuff like physical design, provides IP blocks, managing manufacturing process with TSMC, packaging and testing. Google and Amazon work with system architecture, performance targets, and requirements but Broadcomm as consultant.

renoir• 28 days ago

Look at the SIZE of that chip.

Cerebras stock is down nearly 20% today.

Not only is approach overlapping, OpenAI is also Cerebras's only major customer.

tantalor• 28 days ago

If you're referring to the big circle of silicon, that's a wafer, generally contains many chips (100-1000s).

thrtythreeforty• 28 days ago

For reticle-limit chips, it's on the order of 100. And less than that once you filter out bad dies.

jupr2• 28 days ago

That made me chuckle but I guess if you have never seen one I could see how that assumption could be made.

If this photo is real I wonder what can be revealed about the approach they have taken by analyzing the architecture of what we can see.

arcanemachiner2• 28 days ago

The alt text of the first image describes it as the "Jalapeño inference chip".

As a non-RTFA-er. I'm assuming it's a wafer-scale chip, similar to the ones made by Cerebras.

EDIT: From TechRadar[0]: "The 300mm wafer that both CEOs are holding will generate about 50 to 60 ASICs."

moralestapia2• 28 days ago

Everybody here knows that.

What some don't know (including you) is that the industry is doing wafer-sized chips nowadays, of which Cerebras is the flagship company.

That's why the stock movement could be related, and that is why GP wrote that comment.

That's just the wafer disc. Looks like it was presented to Sam Altman for ceremonial purposes.

The wafer disc is what the CPU gets "printed" on.

Dang, I just checked and CBRS is in free-fall since the IPO.

Sucks, I think they're a cool company.

OTOH, I was the only person back then pushing hard during my time at KAUST (back in 2019) to buy one of their systems when they were nobody, eventually resulting in a partnership between the two.

Then I joined their online discourse, very few users, I was semi-active there but they didn't care much.

Then I came to Toronto and heard they were opening an office here, tried to get noticed several times but got mostly ignored. I asked about upcoming events several times, anything to get involved, "yeah man, maybe one day". Then they made an event during Toronto Tech Week and didn't even tell me ... idk.

I don't get schadenfreude as I still think they're a cool company.

My point is they put all the eggs in one basket (AI inference) and neglected everything else. They seem to be on shaky ground now ... sad.

the use of OpenAI models to accelerate parts of the design and optimization process.

I wish there was more about this. As is I kind of have to assume that this is just meaningless marketing, like saying development was accelerated by Microsoft Office or their 5k LG Ultrafine 40-inch monitors.

Like, if this was as big a deal as it kind of vaguely implies, they would be making a bigger deal of it, right?

dofm4• 28 days ago

Right. There are two possible meanings and shades in-between:

1) OpenAI genuinely have AI technologies that can improve chip design (bold, unlikely claim, needs evidence)

2) OpenAI designed test/verification models and kernels that could be run on the simulated hardware to test its performance

As you and others have said, it's hard to trust when they are happy to write something that could easily only mean the latter but sounds like the former.

lovasoa• 28 days ago

3) The engineers working on the chip used ChatGPT from time to time.

wongarsu2• 28 days ago

Or OpenAI accelerated the design and optimization process by summarizing emails exchanged during the design and optimization process, or made it possible to ask an AI questions about meeting notes

Aurornis3• 28 days ago

1) OpenAI genuinely have AI technologies that can improve chip design (bold, unlikely claim, needs evidence)

Chip design languages (HDLs like Verilog or VHDL) are well understood by LLMs. They don’t need specialty tools to use GPT-5.5 or other LLMs with them.

nixon_why69• 28 days ago

There is a lot of verilog out there, it's pretty feasible that they had AI assistance writing more to design their chip.

It doesn't have to be revolutionary, it could just be AI-assisted design and lined up well enough with their operations for a custom ASIC to be worth it.

Also there's some much boilerplate around everything. Writing a testbench with codex is extremely feasible. This is the kind of verifiable feedback loop the agents shine at.

Aurornis3• 28 days ago

The hardware description languages (HDL) used in chip development are like programming languages. The existing models understand them and can do a lot with them. You don’t need to have separate, specialty models designed for this work to use LLMs in chip design workflows.

Design verification also involves a lot of traditional programming which benefits from LLMs.

So it’s not meaningless at all. You could download some of the open source chip design software today and the LLMs could even help you get started on your own tiny chip if you are so interested.

ses1984• 28 days ago

The question isn’t whether or not they employed a particular tool, the question is how big of an impact did it have.

IshKebab2• 28 days ago

The existing models understand them and can do a lot with them.

In my experience they are not especially good at SystemVerilog. There's a lot of knowledge about it that is locked behind paywalls and it's very niche.

My guess is the "from scratch" here is quite the exaggeration. Otherwise why did they need Broadcom?

knicholes5• 28 days ago

I tried making a button using Claude entirely (including the 3D printed enclosure) and it effed up pretty hard with the traces and the header spacing. The project was a big red arcade button that plays the "ah-my-groin.mp3" when pushed (from Simpsons). It did cool work on saving battery life, and the 3d enclosure was awesome, but yeah, I'm convinced I'd have to do another version or two of the custom chip until it came back right. I used a Blender MCP for the 3d modeling. I used a KiCAD MCP server for the chip design/validation.

I think we're not there yet. I've been meaning to look at this flux.ai to see if it has the prompts/workflow worked out better than what I was able to cobble together in a few hours. Maybe Alteryx's MCP server would have been better. I'll try that this weekend for another board I've got.

nradov• 28 days ago

Most HDL code is locked up behind corporate firewalls and not available as training data. While LLMs can handle it to an extent there's a lot of room for improvement. I'll bet that OpenAI and their competitors are racing to license this IP from major hardware vendors in order to compete in the chip design vertical.

zgao4• 28 days ago

Chip CEO here. It really depends on what "design" or "production" means. Does "design" mean that the design was complete? Does "production" mean the beginning of production, i.e. tapeout? If measuring from RTL-freeze to tapeout, this is a fairly typical (even somewhat unimpressive) timeline (accounting for some unexpected issues) for a large, complex 3nm chip. If measuring from concept (no RTL at all, block diagram of architecture) to tapeout, this is an amazing timeline. The truth is probably somewhere in between. A more concrete statement would use actual technical milestones and gates.

nonethewiser• 28 days ago

Even for a company’s first design?

otterdude2• 28 days ago

Not a chip CEO, but I read this article and thought that they're working on some kind of application specific chip only for serving models. Similar to how an FPGA can optimize certain tasks.

Given constant weights / biases of a Transformer / DNN you could use pipelining to feed forward calculations through the array one layer at a time. For DNN's with thousands of layers you might see 1:1 speed up per layer channel.

I doubt they would undergo this process for marginal gains.

If you look at the timelines for the hiring of the hardware team, this was an extremely fast and high risk implementation from concept to tapeout. Amazing it works at all during bringup.

I feel like "the use of OpenAI models to accelerate parts of the design and optimization process" just means that engineers were using ChatGPT to sanity check their designs and suggest potential optimizations, though that's just my take (and I'm quite cynical about AI marketing in general!)

aurareturn2• 28 days ago

Broadcom already has a ton of IP for AI SoCs. I'm guessing the hard parts of this inference chip was already designed by Broadcom and OpenAI simply told Broadcom what it wanted. It's likely very similar to Google's TPU.

  Early testing shows that the first-generation accelerator will deliver performance per watt substantially better than current state-of-the-art

What is substantial here? Vera Rubin is shipping in volume later this year and it is expected to be 10x more power efficient for inference than Blackwell.[0] Even if they're already taped out the chip, getting bugs fixed, getting chips manufactured, getting HBM allocation, getting a rack design, hooking them up together, putting them in a data center will likely take at least another 12 months or likely more. By the time this chip is in data centers in volume, they're likely competing against Vera Rubin Ultra or maybe even Feynman.

Personally, I don't think OpenAI should have invested in this project. It's too early for them. They should have focused on models like Anthropic and win there. When they're profitable, they can take on these projects.

The risk here is very high for OpenAI because AI has a hard cap in energy. If you have a gigawatt, you should only install the best chips. If Nvidia's chips are better, then this is a wasted project and likely wasted billions.

Why do you assume Broadcom has a ton of IP for AI SoCs but hasn't done any of the other work around data center scale deployments?

AtlasBarfed2• 27 days ago

"Substantial" seems like a damning word.

So one of my pet theories I haven't seen in general discourse is that AI came from the massive vector processing jump available commercially in GPUs when it left CPU bound processing behind. That's a factor of 100x-1000x of processing power.

AI is not-quite-there, and to get even another leap might take another 10-100x processing power.

Now... what? ASICs probably won't deliver even a 10x? There's only so much you get out of node shrinks.

"Substantial" doesn't even mean twice IMO. "Substantial" almost sounds like ... 15% better?

I think this kind of "hard work" is a perfect fit for AI, and something where the complexity for a human is incorrectly extrapolated to LLMs.

Tirelessly wading through heaps of specifications and documentation with very clear goal definitions is hard for a human but easy for an AI. Meanwhile, taking UX and edge cases into account in a business application is easy for a human but hard for an AI.

CA Technologies was much worse than Broadcom in its heyday.

It'd be cool to see more of this type of thing, but I have to imagine the ability for it to be updated to a brand-new model as new models come out is limited. If that is the case, it's going to be an extremely hard sell.

wongarsu2• 28 days ago

A hard sell right now. The rate of change will slow down

cmrdporcupine• 28 days ago

I think the model they chose is out of date and hard to sell, but there are plenty of use cases where today's dumb small models are fine. A Qwen 3.5/3.6 or Gemma 3 model on silicon at those speeds would be genuinely world changing even if it's only 1-3B params. Such a model at those speeds will remain extremely useful even over a 5-6 year timespan, I think.

If you consider the places you could deploy it -- with no network access, and at those high speeds... very useful .. for adding vague "common sense" fuzzy thinking to all kinds of applications that right now piss consumers off with poor UX. Esp if the model can do voice-to-text and text-to-speech well (some of the smaller models can)

empath75• 28 days ago

You don't need SOTA models for all tasks, and being able to do more routine tasks at something like 10% of the cost and 70x speed unlocks LLM use for things that are just unthinkable now (bulk classification tasks, real time speech interaction, etc)

NitpickLawyer3• 28 days ago

extremely hard sell.

It really depends on the pricepoint at which they can get a board. If they can do a ~32B model for 1k$ and a size of an external HDD, I'd buy one now, even knowing that it won't be upgradeable / the model remains fixed. The speeds they've shown are a quality of its own, and there's plenty you can do with such a model and faster than instant responses.

runeks2• 28 days ago

If performance per watt is 100x better than GPUs (as GP link claims) then I don't think it's a hard sell at all. That's actually a cost reduction that matters.

martythemaniak2• 28 days ago

In a chatbot, 17k tok/s is a neat but nearly useless showcase. In a coding agent it is a meaningful improvement. In robotics, it could be an absolute revolution.

8B models aren't useful in general, but for specific use cases they can provide an enourmous amount of intelligence - nVidia's Tesla/Waymo competitor is a 7B LLM with a 2B diffusion model, and running that at those speeds could be an order of magnitude cheaper than existing solutions.

Imustaskforhelp2• 28 days ago

Could you give me some example how in robotics it can be an absolute revolution?

My understanding is that robotics doesn't really rely much on LLM's in the first place but rather other things.

Is the thing that you are suggesting that it would ingest all real time data and then reason through it at an incredibly fast speed and then act on it and re-iterate? I might imagine some problems with this though I am not a robotics engineer and perhaps someone who deeply understands this topic can give more information.

hadlock• 28 days ago

17K tok/s is approaching realtime motor cortex needs for a robot with ~12 actuators (bipedal humanoid) and an IMU. I don't know how many parameters a motor cortex would need but 8B feels like it is within 2 orders of magnitude.

cruffle_duffle3• 28 days ago

Bumping the speed of these things would be more than meaningful. It would be a massive game changer.

I assert like 80% of this “multi agent parallel workflow” business is simply a workaround to models being soooooo slow. Like as the dude driving these things… you kick it off and twiddle your thumbs waiting minutes to hours sometimes for all the inference and token generator to finish. So you dispatch multiple workstreams in parallel to be more efficient.

I assert that if the model was even 10x faster we’d be using these things radically different. You’d be doing things that are currently time prohibitive. At 100x, holy shit will software dev get crazy. You’d be kicking off hundreds of parallel workers attacking a problem from every angle and stuff. Who even knows!!!

And the thing is, 10x will absolutely come and probably even 100x. And it will be sold like a video game cartridge or something depending on how the actual model gets “baked” into the hardware. No remote inference at all.

dcchambers• 28 days ago

I think hardware like this is the future for LLM-providers once we reach a point where the models aren't advancing much any more. You could argue we're close now.

The hyperscalers like AWS will made great use of these to serve up models that will be relevant for several years. But right now, we're still seeing significant bumps in model quality every couple of months - especially with open-weight models like Deepseek/Kimi/GLM.

Until that point, though, I don't see how this is ever going to be cost effective vs general purpose hardware.

I also think we'll see miniature versions of this baked into mobile hardware for super fast and efficient on-device LLMs.

WASDx• 28 days ago

I see only these two possibilities:

1. If LLMs keep improving, burning models onto silicon becomes obsolete too fast and is not worth doing. Outcome: We keep getting better LLMs. 2. If LLM improvements slow down, they will be burned onto silicon. Outcome: We get faster, cheaper and energy-efficient LLMs.

Either way sounds great to me. It will certainly be a mix so we can even get both.

kccqzy4• 28 days ago

seems like soooo much efficiency waiting to be unlocked at the chip level

Well if you are exclusively using GPUs that are general purpose, of course you leave so much efficiency on the table. That’s why Google started making TPUs more than a decade ago. I remember that kerfuffle when Google fired Timnit Gebru when Gebru’s paper used GPUs to calculate the environment impact of LLMs while ignoring the efficiency of TPUs; this basically made Jeff Dean very angry due to that wide efficiency gap.

jacques_chester• 28 days ago

That ... wasn't the kerfuffle

redox99• 28 days ago

These NVIDIA GPUs aren't general purpose in the way that you think. They can't even run games. Nvidia blackwell is probably slightly more efficient than TPUs for training. Do you really expect a 4 trillion company with the majority of its revenue being AI for some years now, not to have built its flagship product fully around AI? The GPU name stuck around, but they are pretty terrible at graphics.

The real efficiency win in these chips is that they are made for inference only. You can throw away the vast majority of a chip if you only need a few ops, a single precision (like INT8 or FP8) and don't need ultra fast interconnects.

qnleigh• 28 days ago

I haven't read any of these papers, but given the environmental impact of LLMs in 2026, it seems like Timnit Gebru has been thoroughly vindicated...

rebeccajae• 28 days ago

It seems technically interesting, but they seem very sparse on details. I don't know if I like the idea of a single unchanging model forever on a chip. How much more expensive would the silicon be if they used rewritable ROM for the weights? Such an arrangement would permit fine-tunes of the model it was designed for, which might minimize concerns about the model becoming outdated.

mdp202118• 28 days ago

There is no memory storage of weights in the Taalas cards but translation of the weight multiplier into a circuit.

flumes_whims_• 27 days ago

Tokens/seconds and watt-hours seem related?

jsenn• 28 days ago

Their demo is almost unbelievably fast, but as I understand it, the limitation of Taalas's strategy is KV-cache. This grows with context length, so either needs to be stored in SRAM (small) or streamed in (slow). Even for a tiny model like the Llama 8B they have in their demo, the KV cache will be ~64kb per token at 8-bit quantization, so at a 1,000-token sequence length you are already at 64MB of SRAM for a single user. This is probably why their demo only lets you generate 1,000 tokens: they can't go beyond that without slowing down inference.

So I'm curious what their strategy is. It seems to me that the options are: 1. Target smaller usecases that can live with a tiny context window 2. Use huge amounts of SRAM (at which point they look like Groq or Cerebras) 3. Make it up with extreme KV-cache compression/quantization 4. Run linear-attention/sliding window attention models

Other commenters have mentioned robotics as a potential application, which sounds interesting.

mdp202118• 28 days ago

Although, custom HW has to be the focus right now - simply because we are dealing with a technology (big NNs) that are not the best match with Von Neumann architectures.

Imustaskforhelp2• 28 days ago

Although this seems to be for inference itself only and not training but inference is a recurring cost and training is a one time cost and so to me, even if Nvidia still gets moat on training, I don't think that it could ever justify its massive evaluations because for example, some chinese models are actually trained on Non-Nvidia models. The moat in that is incredibly thin.

(at the moment), I think that if I were Nvidia, I would be a bit terrified and I imagine the stock to not be doing super great as I can just imagine everyone online might start talking about it for better or for worse.

I am a bit impressed by OpenAI but is this what can be classified as a plan for OAI to salvage itself and all the commitments it has made nearing a 1.4 Trillion dollars from my memory and this article[0] is from 2025

But could OpenAI simply walk out of its commitments when necessary (for example to Nvidia) if this chip works out or what exactly might happen in the future as these commitments are asked to be paid for, its still smart for OAI to diversify with this chip and to have more deeper ways of revenue than just being a simple middleman but I imagine that Nvidia and others have also invested in OpenAI and they must not be happy with this change.

The thing with AI deals are that they have become so complicated that it is hard for me to find the first order impact of things, let alone second or third order impacts and financial accountability seems to be impacted quite heavily because of all of it and there is some sense that it is done so intentionally.

deweywsu3• 28 days ago

With the pace of AI, and with AI helping to pave the way for faster/better AI, I keep wondering if hardware like this will become obsolete well before it has a meaningful ROI. Huge AI models can be run with less resources already through quantization and offloading, but that's just the beginning. One day, maybe not far from now, a breakthrough will allow huge LLMs (say 200B in size) to run well on an old 5 year old Dell desktop. Think that's crazy? Look at the size of the first hard drives. The IBM 350 was a disk with 50 platters, 24 inches in diameter, that held 3.5Mb, and was leased for today's equivalent of $35K.

https://www.computerhistory.org/storageengine/first-commerci...

Compare that to a multi-terabyte ssd. Now apply that improvement to how an LLM is architected and run now. With AI assisting, it won't be long before a leap occurs and these data centers with all their current ultra-cutting edge Nvidia cards are nearly obsolete overnight.

simonebrunozzi• 28 days ago

Interesting comment, but the comparison with hard disk drives is probably unfair.

The IBM 350 was commercialized 70 years ago; it took 70 years for someone like you to be able to compare that to a multi-TB SSD.

Furthermore, nothing says that Moore's Law will necessarily apply to LLMs, for decades to come.

deweywsu3• 28 days ago

Very true, and all I am basing my comment on is the improvement in speed AI has demonstrated when applied to software development, and inferring it might enable a similar 10X or 100X improvement in both hardware architecture as well LLM structure and/or interface methods. If that speed improvement applies to performance of AI, that could mean the 70 years it took for people to improve storage technology might be able to be compressed to achieve a step change in AI performance in a drastically shorter timeframe.

True but as someone else pointed out; at that time we'd be interested in running 200T parameter model rather than 200B. Why, you might ask?

Apple and Google have excelent chips, yet they needed to invest a lot in long-tail software projects to make those chips do actual premium work. Still not state of the art for serving LLMs (although Google is strong in that, mostly because it piggybacked on previous chip-related software work for phones and so on).

londons_explore2• 28 days ago

I wanna see an inference chip where the weights are part of the rom of the chip.

There would be 1 multiplier per weight (and since they're constant, the whole thing turns into a bunch of simple adders), and the total pipelined system throughput would be one token per clock cycle.

That means you can probably have millions of users simultaneously using a single bit of silicon, with perhaps 500 million tokens per second coming out the output bus.

Downside is this chip would be huuuuge - a whole wafer.

Wafer level faults probably won't matter though - neural nets are resistant to a few missing or wrong weights.

Due to the speed the industry moves, you'd want to race from model weights to production super fast, make 50 wafers, use them for a year, then bin them when that model is obsolete.

cruffle_duffle3• 28 days ago

“ Wafer level faults probably won't matter though - neural nets are resistant to a few missing or wrong weights.”

Brain science people “love” traumatic brain injury cases because it can help explore what happens when bits of the “brain wafer” get damaged. We’ve learned a lot from such things.

I wonder if people are intentionally “destroying” parts of the model weights to learn more about what happens? Like could you strategically wipe a gig of the model so it’s “all zeros” and see what happens?

I have to wonder

Smaug123• 28 days ago

By the way, you've seen Cerebras? It's not gone as far as what you described - loads of cores and RAM but you still load up the weights onto it as software and they need to be streamed into the chip for large models - but it is a whole wafer.

trouve_search• 28 days ago

Cerebras is a whole lot of SRAM, basically a ton more L1/L2 cache, hence increasing throughput.

They're pretty supply constrained right now though and their production costs seem prohibitive.

The interesting players at the moment are from Toronto: taalas (print the model onto the silicon) and tenstorrent (dataflow programming based hardware)

londons_explore2• 28 days ago

There is a huge downside to weights being modifiable - it means you need to have multipliers (not simply adders), and SRAM to store those weights.

I suspect for equal performance, that's probably a 5x increase in silicon area (and therefore cost).

> I wanna see an inference chip where the weights are part of the rom of the chip.

I've been wondering about that for a while now. For a lot of tasks putting weights in ROM is probably OK. OTOH:

> There would be 1 multiplier per weight...

I'm not sure that is a good idea. Maybe if its quantized down to 2 bits... Otherwise maybe a small ROM near each multiplier (or row of them or whatever) so the multipliers could handle N distinct matrix operations without having to move the data from far away.

Another fun thought is to have a row of MAC units on DRAM so a DRAM row would be a vector. Row size might be 64Kbit or 8K weights if they're 8bit. This also keeps the weights and calcs on the same chip. I'm not sure this would put enough multipliers on one chip though. Systolic arrays can have tens or hundreds of thousands each doing one op per clock cycle.

cyptus• 28 days ago

analog chips could also be very interessting instead of using digital signals and processing them against the weights in the ROM. I have no idea if that scales with such big models though.

yuriyguts• 28 days ago

I've also been thinking about this. Although the forward pass of a transformer model also involves some heavier operations like normalization, reciprocals, exponentiations or other non-linearities (GeLU, SiLU) which may (though typically don't) involve learned weights as operands.

Not really that: you are pointing to Compute-In-Memory (CIM) - techniques where the data (here, a multiplier value) is part of the processor (here, the multiplying circuit).

I've worked for one of Europe's biggest synthetic biology labs and I know lots of biologists are low-key interested, but current players in semiconductors see it as kind of a tarpit.

IBM used to have a program using DNA origami for lithography back in 2009, which makes sense as lithography masks are a pain to make. I really wish I know why the program was stopped, but most of the researchers are retired by now.

As to whether you can just "grow" the whole chip from scratch, the answer is probably, but it would require lots of non-trivial scientific discoveries. For instance, we can't really make sizable chips using DNA without horrible defect rates. Biology is much better at making redundant rube goldberg machines, than very precise machines with no tolerance for errors.

I think we'd have a better chance of success if we made very weird kinds of chips that better took advantage of the medium, perhaps even something that we "train" rather than just use out of the box.

Using the space of an entire wafer for one chip would result in extremely low manufacturing yields. Even with state of the art silicon cleanrooms, there will still be defects in parts of the output.

With CPUs and GPUs, chip makers can disable faulty cores and bin them as lower SKUs to get some yield out of it. But if you're using an entire wafer to embed weights, and a speck of dust causes a printing defect that makes the weights wrong, the entire wafer is worthless.

kimsey0• 28 days ago

We do. The Cerebras line of Wafer Scale Engines is exactly an entire wafer of cores running in parallel with fast memory next to each one. It's intended for very high throughput LLM inference. https://www.cerebras.ai/chip

One token per clock cycle at 1B parameters would imply 2 ExaFLOPS, consuming about 10 KWs

whazor• 27 days ago

You don't need a single wafer, you can split the model into many smaller different chips and connect inputs/outputs.

Skip VHDL and directly go for GDSII / OASIS. Try to find similar vectors so you get re-usable blocks.

You can dynamically calibrate a chip by fine tuning output.

'braodcom' ha ha ... it's not OpenAI's chip then ...

tehjoker• 28 days ago

No information on how significant the reduction in energy per token is. No information on amortized price per request. Increasingly its clear OpenAI must demonstrate order of magnitude reductions in cost to not die, this is investor story time without that information.

jauntywundrkind• 28 days ago

Is there any actual content on what the chips are?

You can't purchase Microsoft or AWS chips, but both of them do pretty good write-ups on what they've done. https://blogs.microsoft.com/blog/2026/01/26/maia-200-the-ai-...

This seems utterly empty of actual substance.

m3kw9• 28 days ago

They tested on spark model, i bet it's a mix of that with focus on inference speed. Whatever it is, hopefully it shows up with current models as faster. Token/s is as big thing as anything else, and thats where they can really gain some edge over the competition.

I haven't seen this discussed here:

So far, the accelerator is showing cost savings of roughly 50% compared with typical AI graphics processing units, Broadcom Chief Executive Officer Hock Tan said in an interview. - [0]

50% cost saving. The picture changes so quickly, there are still a lot of low hanging fruits, that I find any discussion about whether a vendor has moats, or if they can recoup investment, is moot and futile.

wmf11• 28 days ago

If GPUs have 75% margin then 50% cheaper is no surprise.

epolanski2• 28 days ago

Operational costs far outweight hardware cost.

Schiendelman4• 28 days ago

"Typical" is doing a lot of work there. That could mean much older chips than Nvidia is currently selling.

signatoremo3• 28 days ago

"Typical" usually means typical, i.e. median. Also they are claiming cost saving, not performance. The saving would even be more impressive if much older chips are less efficient than the newer ones -- costing more to run.

paxys2• 28 days ago

Very interested to know the distribution of effort between the two companies. Is this truly a brainchild of OpenAI engineers or did they pay to white label and use a new Broadcom chip?

lifeisstillgood• 28 days ago

So I’ve been wondering about “one or two levels back” chip design. If I understand it, 28nm chips (pre EUV) is just about suitable to run (not train just inference) frontier models.

And so if I was a mid-level State would it be worth while to take my nascent chip industry and push it out to build a 28nm foundry and supporting eco-system.

The models will come but the real challenge of the future is having enough compute power for every one and every use. Even if LLMs don’t become AGI they will still be incredible tools - and as OpenAI seems to spend 8000 for each 200 monthly subscription building one’s own data centres seems sensible

paxys2• 28 days ago

You are underestimating how difficult it is even for a large nation state to attract the kind of talent and investment it would take to set up a chip industry. It is out of reach for anyone outside of the 3-5 largest national economies and a few big American/Chinese multinational corporations.

mdp202118• 28 days ago

Even if LLMs don’t become AGI they will still be incredible tools

(Mostly an aside, but: LLMs have paved the way, now the problem is there, it is a challenge and a geopolitically relevant race... AGI is a goal set: not-having-reached-it will be just a stage.)

wmf11• 28 days ago

28nm chips is just about suitable to run frontier models

I doubt it. 28 nm is 4-5 generations back so inferencing would need a large number of chips with very high power consumption. Maybe you're thinking more of 7 nm which is what Chinese fabs have; it seems to be OK for companies like Huawei.

And so if I was a mid-level State would it be worth while to take my nascent chip industry and push it out to build a 28nm foundry and supporting eco-system.

It never reaches breakeven so you'd have to provide billions in subsidies per year forever. The sovereign chip stuff only makes sense for the US and China; even the EU probably isn't large enough to make it work. A single country definitely couldn't.

eggsome• 28 days ago

But the energy requirements per token would be orders of magnitude worse than chips made at 3nm. So probably better for your hypothetical state to just pay the extra for more efficient chips so that they don't have (as much) of an energy problem.

This is why ram prices are fucked. Cause altman doesnt give a shit about normal people as long as openAI suceeds

groundzeros20152• 28 days ago

This is starting to sound like startup scope creep. Instead of making the AI model it’s now custom silicon, web browsers, and consumer electronics?

glaslong• 28 days ago

Definitely has that smell... At the same time though, they NEED inference cost to drop substantially, and even better for them if it only happens for their models on their hardware.

I assume they're doing everything they can to make that happen model-side, but coming at it from the other end makes sense too if they can swing it.

brcmthrowaway2• 28 days ago

Nearly all those initiatives have failed though

guywithahat2• 28 days ago

Maybe, but they’re also a massive company. At some point Google stopped being a startup and become a massive company with margins to look after

groundzeros20152• 27 days ago

After they were wildly profitable.

krick• 28 days ago

But there never really was a moat in LLM?.. I mean, I don't know where you stand, but my perception is that we all kinda knew that the whole time since 2017, and really knew that since DeepSeek. What they really care about is:

1. Customer acquisition.

2. Cheap(er) electricity/hardware.

So it's really surprising to me that them making their own chip surprises anyone at all. The electricity thing is already kinda being taken care of by earlier strategic alliances with some other evil people, the chip is a natural next step.

The only time I've ever seen that name before is when trying to solve driver issues, on both Linux and Windows.

Are they especially stingy with their IP related to drivers or something?

Because they have the skills necessary to help bring custom designed ASICs to fruition. Google uses them for their TPU's, Meta uses them for their custom ASICs as well.

nullbio• 28 days ago

Big tech AI labs will develop LLM accelerators and hardware LLMs that increase frontier model output to tens of thousands-hundreds of thousands of TPS.

These chips will be used internally for their own business goals, giving them the capability to iterate at such an insane pace they will be able to clone every software product and software company on Earth. Meanwhile they'll trickle out 100-300 tps access to the rest of subscription users to drain them of their cash and keep the beast fed with fresh training data.

How can any individual company building a product, with access to 100-300 TPS behind-frontier security-gated, censored and capability gated models expect to compete with a company like Anthropic or OpenAI with frontier, unrestricted, unlocked models that can produce 100-1000x the output? 3-5 of their employees working to clone your 500 staff business will likely be easy pickings for them.

This should concern everyone.

The only reason they aren't 100% in on the strategy of replacing everyone is because they need us for training material and they needed the bootstrap. But the bootstrap problem is already gone, and they don't need to give us fair access to keep training data rolling.

So this mafia is driving up RAM prices. And now build their own overpriced hardware.

Either RAM prices go down, or that mafia must pay us all compensation money for this cartel build up. Why is the USA protecting this? How much does the orange man profit personally from helping drive up the prices here?

I don't have much confidence in either OpenAi/Sama nor Broadcom, given past history. Again this is just pre-IPO shenanigans.

As credible as the "Datacenter in Space" claim by Elmo, before the SPCX IPO.
