Again, that's not a moat. The original "We Have No Moat, And Neither Does OpenAI" leaked memo from Google that memefied the term focuses explicitly on the increasing ease of competitors (especially open-source) entering the ecosystem: https://www.semianalysis.com/p/google-we-have-no-moat-and-ne...

HN discussion> In order to break even they would have to minimize the operating costs (by throttling, maiming models etc.) and/or increase prices. This would be the reality check. Is that true? Are they operating inference at a loss or are they incurring losses entirely on R&D? I guess we'll probably never know, but I wouldn't take as a given that inference is operating at a loss. I found this: https://semianalysis.com/2023/02/0…

HN discussionThe fact that TSMC publishes their own metrics and target goals for each node makes it straightforward to compare the transistor density, power efficiency, etc. The most interesting aspect of the M4 is simply it's debuting on the iPad lineup, whereas historically it's always been on the iPhone (for A-series) and Macbook (for M-series). Makes sense given low expected yielded for the newest node for one of Apple's low…

HN discussion> uses an _embedded_ silicon interposer It sounds like they're using TSMC's new LSI (Local Si Interconnect) technology, which is their version of Intel's EMIB. It's essentially small islands of silicon, just around the inter-chip connections, embedded within the organic substrate. This gives the advantages of silicon interconnect, without the cost and size restrictions of a silicon interposer. It would not be visibl…

HN discussionI think you'll be surprised if you see the lift karpathy demonstrates from `fineweb.edu` vs `webtext` (he went back later and changed the `nanogpt` repository to use `openwebtext` because it was different enough that it wasn't a good replication of GPT-2). But from an architecture point of view, you might be surprised at how little has changed. Rotary and/or alibi embeddings are useful, and there's a ton on the infe…

HN discussionI think they will be, but more for hand-off. Local will be great for starting timers, adding things to calendar, moving files around. Basic, local tasks. But it also needs to be intelligent enough to know when to hand off to server-side model. Android crowd has been able to run LLMs on-device since LlamaCPP first came out. But the magic is in the integration with OS. As usual there will be hype around Apple, idk, in…

You are absolutely right, I apologize. I think I was talking about A100 prices (which are still only 6 years old) and conflated a few different things there. But A100 rental prices have climbed since 2024 (as far back as free account records show on https://semianalysis.com/gpu-pricing-index/ ). Coreweave has announced they will keep A100s in use until 2029 which will be 9 years old then. I think that is where I got…

> These companies have been caught tweaking their numbers... they build data centers through holding companies, who have to absorb the costs and massive capex based financial liabilites, so that the brand-name big-tech companies get to keep their expenses off their books. This is about as far from "tweaking their numbers" as you can get. It's a standard way infrastructure-heavy industries structure their investments…

Someone said you'll eventually move to HDM because SRAM improvements is relatively stalled.
