Probably obvious but still omitted in the OpenAI post: chips are being made by TSMC [1]. Wasn't sure if Intel got it.

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.

by alephnerd an hour 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.

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.

> 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 after acquiring CA Technologies, BMC, Symantec, 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.

Did they acquire also BMC?

Good information, Broadcom is a playa, lots and lots of acquisitions! (a quick google search turns up a very eventful history for Broadcom)

Only The Paranoid Survive is quite a name for a management book. It implies surviving in the world you are speaking about.

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.

by skeledrew 2 hours 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.

> 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.

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.

by forrestthewoods 2 hours ago

Inference costs are higher than training now. I think.

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

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

I'm sceptical over any pre-IPO announcements.

I have been eyeing what Taalas is doing [1] by making pure hardware models. The speed is absurd.

by mikewarot 3 minutes ago

They talk about products, but they don't sell the hardware, thus they don't really have a product, just a service.

I know, it's nick picking, but when people can just reach in and take services away, like Fable/Mythos, hardware is the only thing worth buying.

What are the other phases. Or what are you referring to in general?

by kilroy123 3 hours ago

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.

by wmf an hour 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.

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

by HarHarVeryFunny an hour ago

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

by Legend2440 2 hours ago

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

by satvikpendem 2 hours 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.

by fennecbutt 2 hours 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.

by MichaelNolan an hour 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.

by ipdashc an hour 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?

by topspin 4 minutes 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.

by wmf an hour ago

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

aw shucks nvda has some spicy competition

Make sure you all use that fancy ñ

by boarush 2 hours 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.

by gravypod 2 hours 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?

by wmf an hour ago

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

by fibonacci112358 3 hours ago

So this is where all the memory they bought is going to.

how much does this chip help with inference speed?

by wmf an hour ago

It's probably the same speed but cheaper.

by flyinglizard 15 minutes ago

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.

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.

No worse, I suppose, than, the obsession with Lord of the Rings that the authoritarian surveillance companies have. Palantir, Anduril. Then we have the not defense/surveillance ones: Mithril, Valar, Narya, Erebor

by skeledrew 2 hours ago

What kinds of names would you suggest?

by thewebguyd 2 hours ago

None, probably. Just saying Jalapeño is no worse than any other non-descriptive company name. Although at least Palantir and Anduril are aptly named for what they do. The VC firms less so.

by anthk 9 minutes ago

Don't worry, in Europe it's the same, but for insurances/lawyer stuff. Tons of companies have names based on Latin words such as Civitas/Insalus/Legalia/Legalitas or whatever which looks tacky/rancid/old fashioned kilometers away.
