Having worked with people doing bringup of specialized chips, I am awed at how the world has changed.

> When the first chips came back from the foundry in May, the team pointed its internal AI models at designing software to run benchmarks such as SemiAnalysis’s InferenceX. On DeepSeek’s multi-head latent attention kernel benchmark, performance climbed from 0.31 percent of the theoretical ceiling (set by the chip’s compute and memory bandwidth) to 88.94 percent in roughly 40 hours. Ho says this result is repeatable, so the time between when foundries deliver the first chips and when production ramps up can be reduced. “All our schedule assumptions are going to be based on the fact we have this capability now,” he says.

Back in the day you'd write the code before the chip came back but I guess today it's faster to wait.

is the world we live in, planning things while waiting for a more powerful LLM

With a few handy tips and tricks from apple insiders. But sure, I guess the LLMs helped too.

The lawsuit isn't for chip designers, but the consumer product lines. It's possible they also got IP for chips, but that was not brought up.
m4rtink [3 hidden]5 mins ago
Yeah, how could those people even think of switching their owners!
stingraycharles [3 hidden]5 mins ago
Didn’t they not just switch employers but actually handed over a lot of proprietary documents from Apple?
stogot [3 hidden]5 mins ago
This is the part forgotten. Apple is claiming this is their IP embedded on chips that OPenAI stakes the future on. Will they settle?
wmf [3 hidden]5 mins ago
The lawsuit appears to be about consumer devices, not NPUs or ASICs. If you think Jalapeno stole from anyone it would be Google.
mathisfun123 [3 hidden]5 mins ago
You people are so weird - gossiping on a site that literally reported the news as it broke smh. It's like sitting in the back of class gossiping about the popular kids.

Newsflash that lawsuit is about product designs not accelerator ASICs. And there wouldn't be anything to steal because Apple doesn't have any DC class accelerators.

Seems pretty obvious now that OpenAI is just hyping their models in order to get companies (in this case, chip developers) to use their products in order to learn from their (exfiltrated) IP. Any corporation would be foolish to use any of their or Microsoft’s products, particularly those with valuable IP. There’s nothing in the article that says AI did anything creative but rather that it was used for software development within the overall project. Clear misleading title. Suggest to mark this as clickbait.

IEEE Spectrum is such a good publication. Early in my career I worked at a place where the magazine would be passed around every month with a coversheet listing all us engineers we had to pass it around and sign we had read it. Been a while since I visited the website but love what they did with it.
Kwpolska [3 hidden]5 mins ago
Every time their content appears here, it's a very shallow analysis written for a barely technical audience. And this article is no different, it's just "slop machine wrote verilog; all the hard bits were done by Broadcom, who have access to public AI models (we didn't talk to them and don't know if they used them, but ClosedAI wants us to think they did)"

Like, why couldn't they invent a new word and not hijack an existing word?

At some point people will use an LLM to design an Apple M series competitor.
Lramseyer [3 hidden]5 mins ago
Production grade CPU design is more than just the RTL (the source code.) To achieve the performance numbers that these companies get, you have to do a ton of optimization in your physical design to achieve the power/performance/area (PPA) metrics that make these products competitive. LLMs are not suitable for that kind of work.

There are people working on PPA optimization and trying to shake up how things are done, just not with LLMs.

menaerus [3 hidden]5 mins ago
> LLMs are not suitable for that kind of work.

I wonder why not or you meant not suitable yet?

Systemerror7A69 [3 hidden]5 mins ago
This is just speculation on my part, but LLMs work best when they get immediate, verifiable feedback on their task, and the kind of physical optimizations they mean might not give that to LLMs.
btown [3 hidden]5 mins ago
Something that I think is fascinating, though, is that labs are no longer beholden to the limitations of commercial design software. Want to replace your simulator and optimizer with a fully custom verifiable stack of Lean proofs of optimality and correctness? Just throw your unlimited token budget at it.
xpct [3 hidden]5 mins ago
I don't work in the business, but my understanding was that even with these companies' budgets, it's still too expensive to do any kind of verified performance optimality.
thfuran [3 hidden]5 mins ago
And I think correctness for anything near the size of a CPU is off the table.
xpct [3 hidden]5 mins ago
Isn't that weird? The full knowledge of how to make such chips may one day be accessible to anyone, yet only the entrenched companies will remain the makers.

If we imagine machines being able to do the full process end-to-end, and the quality of that process only dependent on capital spent on tokens, I don't see how new companies could ever enter the market.

bhouston [3 hidden]5 mins ago
It is probably doable right not to push a risc-v design into that performance space.

And be super-bankrupted by patent litigation from Apple. I don't think they're worried.

After all, they successfully threatened Adobe with spurious patent litigation unless they joined w/ apple in illegally fixing wages.

You don't think a criminal like apple would absolutely decimate any competition given the opportunity? They didn't hold back when it was a unambiguous crime, they surely wouldn't if it was merely bad for the world.

bigyabai [3 hidden]5 mins ago
They won't, because they'd need an ARM architecture license.
nr378 [3 hidden]5 mins ago
Qualcomm have an architecture license and the Snapdragon X2 Elite Extreme X2E-96-100 isn't too far off the M5 Pro.

bigyabai [3 hidden]5 mins ago
Are they using LLMs to close that gap, or is this their Nuvia acquisition doing the heavy lifting?
pazimzadeh [3 hidden]5 mins ago
watt about in performance per watt?
amelius [3 hidden]5 mins ago
Why, the LLM can make up its own architecture.

The value lies in the design space exploration, which is what an LLM can easily do.

https://en.wikipedia.org/wiki/Design_space_exploration

wmf [3 hidden]5 mins ago
Arm sells architecture licenses to anybody these days.
cmrdporcupine [3 hidden]5 mins ago
Or they'll just build a competitor in RISC-V instead and that's fine.

Except the problem is not restricted to the actual ISA or its HDL implementation, etc.

It's even just getting space / time in a fab at that advanced of a process node.

pixl97 [3 hidden]5 mins ago
I mean you can design anything without a license. Selling it is where the problems come up. Even then there are likely places in China that would still make it for you.
globnomulous [3 hidden]5 mins ago
> Jalapeño can reduce end-to-end latency (the time between prompt to last token) by up to 3.6 times

I'm never sure what on earth this kind of impressionistic math is supposed to tell me. Is the comparison between 4.6 and 1.0? 3.6 and 1.0? Clearly the comparison isn't supposed to be 1.0 and -2.6, even though that's what the words literally mean. I can't be the only person who finds this infuriating and distracting. These numbers shouldn't be impressionistic. They should be precise. That this is an article on spectrum.ieee.org makes the imprecision all the stranger. I'd expect their readershipt to care, for instance, about what's even being measured. Is this the geometric mean of something? The arithmetic mean? And what latency has improved?

gozucito [3 hidden]5 mins ago
It is surprising to me that recursive self-improvement seems more plausible now than it did in 2023. Am I the only one to be surprised?

I remember the paper proving that hallucinations could never be fully solved back in 2024: https://arxiv.org/abs/2409.05746

I also remember the hang-wringing about running out of new datasets to train on. Now it appears humans are always generating more data. It's just not as cheap to acquire as legacy data? Meta has to give a deep discount on their API prices to entice people.

I thought back then that humans had a few more breakthroughs in them as meaningful as the seminal Attention is all you need paper. Enough to 100x the capabilities of LLMs back then (10x the smarts and 10x the speed simultaneously).

RSI with a 20 month turnaround for a chip to be made is not exactly breakneck speed though. Physical manufacturing and logistical constraints are going to be and remain a hard obstacle to that process for the foreseeable future.

red75prime [3 hidden]5 mins ago
> I remember the paper proving that hallucinations could never be fully solved back in 2024

The papers that use the halting problem or the Gödel's incompleteness theorem to prove something about LLMs are dime a dozen. The problem is they prove their results for any computable system. You need to also believe that the human brain contains "magic" to think that humans are exempt.

I believe I've said the same at the time this paper was published. There is no need for hindsight to notice the problem.

The required amount of compute and training data and whether the existing training methods were up to the task had the real potential to be show stoppers though.
