Agreed. Economies of scale are about the only way this makes sense.

I was just working thru the use case for purchasing a 64gb Strix (vs the typical coding I might do using OR or Open Code Go). The ROI is somewhere in the order of 7-10 years for me. So, on a purely dollar cost basis, local inference is $$$. OTOH, from a sovereignty and "own your own code" basis...there's something to be said for it.

Probably I will run a few tests using OR with a few outstanding tickets of mine, to kick the tyres of Qwen3.8-27B. I've tried Qwen3.6-35B and frankly it's...not very good at code gen or patching.

To boot, code gen isn't the only thing I use LLM for, so I suppose it depends on how bloody minded I want to be about future use case (I do actually have one).

    Of course they do...but it's not stated in the costs they cutely described as $0.3/1M tokens.

    The ones GLM5.3 worked thru ($3.5M capex, based on GPU costs) didn't include ongoing colo costs. So, figure on $3.5K + whatever site rental and electricity cost (I read the article to suggest they were using a colo not on site, but the same idea stands either way: no free lunch just because you have the hardware)

    BRB, just getting some scratch lotto tickets.

    14.3 kw. That's fucking obscene.

    And by all rights, the Fintech datacentre is what...small? medium?

    GLM again:


    One DGX B200 flat-out: 14.3 kW × 24h = ~343 kWh/day ≈ what a typical UK house uses in a month

    Datacentre size: a full rack of AI gear like this is ~50–100kW. Classification-wise:

    Your average office server closet: 5–20 kW
    Small datacentre: <1 MW
    Mid-size / enterprise: 1–10 MW
    Hyperscale (AWS/Google/Microsoft): 50–500+ MW per campus
    

    Revolut's 56 GPUs ≈ one dense rack or two — well under 1 MW, so firmly "small," and that's exactly why they colocate/rent space ("a US-based service") rather than owning a facility. Self-hosting the GPUs doesn't mean self-hosting the building. You don't put 100kW of fridges in your London office — you rent rack space in a proper colo where the power and cooling already exist.

    Enjoy the lotto. If you win, you can buy an eighth of a DGX.


    Fuuuuuuuuuck

    In the spirit of things, I asked GLM5.3 what that set up actually looks like. Ouch.


    Fetched that page for real. Specs (from gpuworld's DGX B200 datasheet page):

    Dimensions: 17.5" W × 87.5" D × 42.9" H (cm: 44.5 × 222.3 × 109.0)
    Weight: 275 lb (124.7 kg)
    Rack height: 10U equivalent
    Power: up to 14.3 kW max per system
    

    In real-world terms:

    Height: 10U = 10 rack units = 10 × 1.75" = 17.5" tall — about the height of a bar fridge standing on its side. But that's the chassis; you'll also want ~2U of clearance for airflow/management, so plan for ~1.5U of breathing room above it in a rack.
    Depth: 87.5cm = just under a metre — so it'll stick out of a standard 1m-deep server rack unless you've got deep racks (or you let the back panel hang open). Standard 42U racks are typically 1.1–1.2m deep to handle this.
    Weight: 275 lb / 125kg. That's a hefty man's weight — two people minimum to lift, ideally four or a rack lift. Standard datacentre floor loading is usually fine at this density but worth checking if you're stacking multiple in a rack.
    

    Rack math for 7 units: 70U of just these systems — so a single 42U rack can't hold them all (you'd need 2 racks), and at ~14kW each you're looking at ~100kW total draw — that's serious power/cooling, way beyond a standard office closet.

    Short version: think "fridge-sized box, half a tonne with rails, eats 14kW" — not a pizza box.

    • *for certain definition of self hosted.

    Developed by Chinese open weights model dev Z.ai, GLM 5.1 isn't exactly a small model. At roughly 754 billion total parameters (40 billion activated for each token generated), the model requires roughly 380 GB of GPU memory just to hold the weights and another 6-26 GB per user to maintain context depending on precision.

    To serve GLM-5.3 at scale, Revolut deployed 56 Nvidia B200 GPUs, equivalent in GPU count to seven eight-GPU DGX B200 systems. But as Abitbol noted, the greatest performance gains didn't come from adding GPUs, but rather tuning the model's hyperparameters along with switching to NVFP4 quantization, implementing disaggregated prefill and decode, and tuning context lengths.

    Why should I give a flying fuck? I have 3 lenovo tiny boxes, a Rpi4 4gb I got pre 2020, a stack of old laptops and phones, a compute stick and 4 tablets. And if I want to tinker (and I do), ESP32 + CYD is hard to beat.

    The Pi 5 does nothing for me that I can't do faster or cheaper (or both) elsewhere. I could literally spend $20 on a WYSE thinclient to get something that's 3-4x the pi while being comparable in power draw.

    No...if I want a shiny, I'll get a FPGA or a Commodore 77. If I want to thinker, I'll get ESP32s. And if I want low power always on compute...well, I'm good thanks.

    I don't understand. So, if VLC was downloaded from Tucows or GitHub...who pays? Surely not VLC, because as I read it, this taxes "producers of digital data" but the measurement mechanism is ISPs counting bytes by sender IP.

    So if a French user downloads VLC from Tucows, Sourceforge, or Akamai's CDN, the bytes come from Tucows/Akamai's IP, not VideoLAN's. Under a strict sender-IP reading, Tucows pays, not VideoLAN.

    Wat?

    If in some crazy world this actually goes ahead as written, one of two things happen

    1. Everyone on earth geoblocks French IPs
    2. Everyone dumps everything onto mirrors and washes their hands of it.

    Starting in December, Plus, Pro, and Business plans’ usage allowance will be shared across ChatGPT and Codex.

    OpenAI confirms that:

    • ChatGPT and Codex will share a token-based allowance.
    • Instant chat will not consume this allowance.
    • More complex tasks and advanced models will consume more tokens.
    • Users can check their remaining allowance under Settings → Usage.
    • Users can purchase extra credits if they exhaust their allowance.

    TL;DR - ChatGPT conversations that use advanced reasoning will compete with Codex for the same allowance. And it will be token based, rather then message / turn based. How many tokens? Fuck you, that's how many. Want a coder and chat with a non brain dead LLM? Pick one.

    So, if you're thinking of re-upping your OpenCode Go or OpenRouter access (or you're fortunate enough to have a rig that can run Qwen3.8 27B, Flash or the soon to be arriving Qwen 4's), now's the time to fuck off jippity.

    Personally, I'm going to ditch it for OR credits and selective use of GLM, Kimi etc for code review. I don't have the rig for a local GLM :(

    Ride was always going to end but fortunately, open weight models are a thing.

    Now if I could only run Qwen3.8-27b at not minutes-per-token...
