> 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?
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.
That's not to say I expect they'll ship something competitive with Google's custom AI hardware on the first go, since Google has been at it for quite a while, but there's very few technical problems large sums of money won't solve.
IDK how the custom hardware exploits this; would love to hear any ideas!

If you can build chips that could run one specific LLM 100x faster than anything else, it would have a use case that nothing else could match.
That, if used in war, I would think, would need the ability to be updated frequently. For example, your enemy might find out (say by running tests on hardware they captured from you) that painting some red paint in a particular shape (a smiley might even work) on their hardware prevented your drones from attacking them because it confuses that pattern with the Red Cross logo.
[1] Yes, this is a massive simplification
And the high water mark of what can be solved by open models will keep going up.
In contrast, tomorrow’s models will typically run, although perhaps more slowly, on general-purpose inference hardware that was released today or even years ago.
Even for a company’s first design?
The Fire Phone was Jeff Bezos' personal baby, and we know how that went. Then there was the Apple G4 Cube with Steve Jobs, the Model X' Falcon Wing doors and Elon, and lets not even talk about the Metaverse and Zuck.
Because the CEO was behind it, breathing down their necks.
If you consider that outcome a worthwhile endeavor, I don't know what else to say.
He's talking about an endeavour reaching the market.
I'm sure if Zuckerberg wants to spend $10B on Nuclear Fusion it will happen.
https://www.esgdive.com/news/meta-inks-nuclear-deals-terrapo...
…and if they do all of this, it’ll be closer to $20B than 10!
I'm talking fusion because it's something out there. And in the context of something like the metaverse.
Fission is something you can buy today at retail.
Even my poor country has a Nuclear reactor.
(Also yes, I'm serious.)
(Doesn’t seem like something to move fast and break things on - change my view?)
Is this a “we can technology our way out of anything” stance?
Fission is something you can buy today at retail.

I'd rather guess that Jeff Bezos' opinion on what makes a good phone is/was different on the opinion of many potential buyers.
I imagine when you are a billionaire from one company, every time you hear the name of the company you hear your name, so you can't really think about what Joe Schmoe wants in a phone independently of your ego.
I guess this is what Steve Jobs was better at. SOME focus on the customer independent of his ego and Apple Apple Apple. I did say ... SOME.
As another commenter said, Broadcom is very experienced with backend design (as well as the supply chain management, testing, etc. that comes after the chip is taped out) and so this can't be regarded as a "first chip". Richard Ho (the head of hardware at OpenAI) is also extremely experienced and used to be the head of the Google TPU effort -- where he actually worked with Broadcom in a similar tapeout already. So yes, this is not a "first design"!
A big part of the semiconductor industry also operates on a reputation basis. Broadcom (like TSMC) is a neutral party as a design house, but if they did something like this, it might ruin that reputation.
My recollection is that PA Semi was very much for the architectural and design talent, even though it was an “asset purchase” and all the existing Power & military chips were hived off.
For Intrinsity I recall a lot of interest was actually in their existing graphics work and EDA. ISTR that those early mobile GPUs were what they focused on.
I was in the mansfield org circa ‘07-11. I spent a lot of time flying between cupertino and austin/bee caves that first year.
Whoever it was, whooo, that's hot shit. I remember an M1 MacBook Air just cleaning the clock of an Intel MacBook Pro and thinking "x86_64 has real competition again".
Great silicon. I'm over it with not having root on my own machine, so I've left the ecosystem, but it's really nice hardware, can't dispute that.
And a lot of them are sitting under Qualcomm via the Nuvia acquisition.
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.
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.
PCB design and 3D CAD design are different topics.
Hardware Description Languages are closer to programming languages than CAD. Look at some Verilog to get an idea - https://en.wikipedia.org/wiki/Verilog
This is very unlike how FPGA and (I assume) ASIC is done. That is more like a traditional programming language but everything happens all at once (no sequence of statements outside tests, if you need that you have to write a state machine yourself). You define logic expressions between signal, add stateful latches, etc. But you never specify the physical layout.
Instead you feed your description to a tool that acts a constraint solver/optimiser that computes the layout for you (this is for FPGAs called synthesising IIRC, it is akin to a compiler). Typically quite slow, even for small circuts like we did at university it took minutes, and for large circuits it might easily days.
Now, this raises the question, what if you design a PCB net list using AI, but then use traditional autorouting and layout? I believe that can also be done, but I have no experience designing PCBs, so I don't know how well it works.
Pretty sure someone already tried throwing VLMs and diffusion models at this, wonder how that fared.

Disclaimer: I work at InstaDeep, the company behind DeepPCB, but I don't work on this product.
And the two things that take up VAST amounts of time in ASIC design are testbenches and timing closure.
A LOT of hardware design is testbenches to verify things. AI is REALLY GOOD at generating things like testbenches. And nobody really cares if the quality of your testbench code sucks as long as it validates what it claims to.
I don't know how good AI is at timing closure, but I wouldn't necessarily be surprised if it is pretty good at it up to the physical point. That's lots of textual output which you can put a constraint on.
Everything involving physical design, though, tends to be a disaster waiting to happen if you let AI loose on it.
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?
* Physical design team (stupidly known as the "backend"). This is extremely specialised knowledge and most chip companies don't really want to have to deal with it if they can avoid it.
* IP blocks. Especially for annoying things like phys, memory controllers, USB controllers, PLLs, power, etc. These things are difficult to do, difficult to test, and often critical (good luck if your clock doesn't work...) I would not at all be surprised if Broadcom supplied CPUs too.
My total guess at what happened is Broadcom supplied most of a SoC and OpenAI added an LLM coprocessor module to it, and probably asked them to add like 10x more DRAM interfaces.
No they don't.
Early testing shows that the first-generation accelerator will deliver performance per watt substantially better than current state-of-the-art
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.

I don't know how much of the things outside of the chip Broadcom has vs Google's proprietary tech that is not shared with Broadcom.
Nvidia's Vera Rubin has 6 unique chips working together in a single rack.[0]

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?
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.
Is it worth the claim that they are making in a press release?
Definitely, yes, because being vague about it like they have been lets investors fill-in-the-blanks with whatever they want it to mean.
Other companies? Fool me once Altman, let's see the thing at scale making money.
Near frontier AI is clearly relevant to some kinds of logic design, I'm learning some Hardcaml at the moment and yeah, AI is super helpful.
Can it leapfrog a company without hardware experience to near the front of the pack of companies with decades of hardware experience? Less obvious.
Unrelatedly, would OpenAI dramatically overstate something to manipulate the press and public and capital markets?
It's arguably their core competency .
AI is going to matter in logic design and synthesis. How much, how soon, and where are open questions.
"The future is here, it's just not evenly distributed"
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.
You could even try it yourself with open source chip design tooling if you wanted to see it.
It is still a bold claim and it still needs evidence.
We would obviously get a bit more of the evidence if it were to be more useful for the upcoming IPO than this rather open-ended, reinterpretable phrasing.
No, obviously. They'd be expected to do a substantially worse job and yet still drastically accelerate the design process.
LLMs make all sorts of dumb mistakes when writing c++ or python yet are nonetheless massively beneficial.
I've used GPT-5.5 and Opus both for FPGA design with good results. We built a lot of tooling around it to help the models, but even without that they're definitely capable of designing digital logic.
This actually plays out across every field and is well documented. An expert can recognize the hallucinations and bullshit coming out of LLMs, while non-experts see plausible output and do not know enough to know it is BS.
Why is that a bold and unlikely claim?
Are you saying that AI, which has been proven to cure diseases, solve our hardest math problems, write complex computer code and generate entire generated worlds and HD video from a simple prompt would somehow be like, my bad, I guess I can't design chips?
We're not quite there yet :)
https://en.wikipedia.org/wiki/List_of_unsolved_problems_in_m...
Because they could have offered even slightly more evidence.
They're burning more cash than pretty much anyone else and doesn't have anything public that looks like a matching revenue stream so they probably need one very badly.
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.
honestly you don't realise how much more efficient it is until you are stuck using the wrong flavour of outlook, the spam filter breaks or sloppy spelling, punctuation and grammar force you to clarify details needlessly.
Without context, both are warnings about the quality of the developers.
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.
something can be non-novel in the industry, yet novel to the reader, at which point it is useful ... for such readers.
FWIW, Google is now on their 8th generation TPU, having put out the last 4 generations on a 1-year cadence.
Remarkable that the TPU pre-dates the attention paper. Was a solid bet on energy efficient dense matrix multiplication and has stood the test of time.
