    Používat H100 jako AWS cluster má asi takovou logiku, jako vzít epoxydovou desku a namontovat ji místo sololitu na skříň z ikey. Technicky to rozhodně jde, ale je to lehkej overkill stavebně a těžkej provar finančně...

    DOKIS: ako som uz pisal ma to svoje pro a proti, ked mas vlastnu infra, tak sa tazko planuje spotreba - viz. tuto skalovali rychlejsie nez stihaju adaptovat softwarovy model, ale zasa mozes kapacitu za peniaze poskytovat inym a ked si infra kupujes na cloude, tak skalujes lepsie podla svojich potrieb, ale zas kazdy CPU cyklus platis poskytovatelovi

    TLDR- They (xAI) turned a not-perfect training cluster called Colossus 1 into a money-making rental to Anthropic, while building a better one (Colossus 2) for themselves. Smart engineering + smart business! Win - Win.

    Musk has been talking about selling access to compute (AWS-like) for AI tasks on several occasions. Even with crazy sounding ideas like having the chips in your Tesla car do inference tasks at night. But people to pay enough attention.

    PES: Vsak ti to rikaj kluci z Fantastic Future od 31prvni minuty novyho dilu..to co jsem ti ja rikal par dni zpet. Bude pronajimat vykon Collosu1 kterej je starsi, bude to konkurence AWSky, Anthropic jako byvali zamestnanci OpenAI potrebujou vykon, protoze Claude je na spici a chce se tam udrzet..xAI tim pokreje ztraty a bude trenovat Groka a dalsi veci na Collosu2, kterej uz je na novejch grafarnach. Nekdo tomu rika 5D sachy. Nekdo kdo pres 20 let podnika jako ja tomu rika spis skvely vyuziti prilezitosti :)

    Many observers point to what looks like a contradiction: Elon Musk poured enormous capital into building Colossus, only to hand the core asset over to a direct competitor in Anthropic. Others read it as xAI capitulating because it is a "middling frontier lab." But these are surface-level reads.

    Look at the numbers and a different picture emerges. xAI today holds roughly 550,000+ GPUs in total (on an H100-equivalent performance basis), and Colossus 1 (220,000 units) accounts for only about 40% of the total available capacity. Colossus 2 — built entirely on Blackwell — is already operational and continuing to expand. Elon kept the all-Blackwell homogeneous cluster (Colossus 2) for himself and leased out the older, mixed-generation Colossus 1. In other words, he handed the pain of rewriting the stack — the MFU-11% debacle — to Anthropic, while keeping his own focus on training the next generation of models.

    The real point, then, is this. Elon's objective appears to be positioning ahead of the SpaceXAI IPO at a $1.75 trillion valuation, currently floated for as early as June. The narrative SpaceXAI now needs is that xAI — long the "sore finger" — is not merely a research lab burning cash, but a business with a "neo-cloud" model in the mold of AWS, capable of leasing surplus assets at high yields.

    From a cost-of-capital perspective, an "AGI cash incinerator" is far less attractive to investors than a "data-center landlord generating cash."

    As noted above, the most important detail of the Colossus 1 lease is that it is for inference, not training. Unlike training, inference requires far less tightly synchronized inter-GPU communication. Even when the chips are heterogeneous, the workload parcels out cleanly across them in parallel. The straggler effect — the chief weakness of a mixed cluster — is essentially neutralized for inference workloads.

    Furthermore, with Anthropic occupying all 220,000 GPUs as a single tenant, the network-switch jitter (unanticipated latency) that arises under multi-tenancy disappears. The two sides' technical weaknesses end up complementing each other almost exactly.

    One insight follows. As a training cluster mixing H100/H200/GB200, Colossus 1 was an asset that could only deliver an MFU of 11%. The moment it was handed over to a single inference customer, however, that asset transformed into a cash-flow asset rented out at roughly $2.60 per GPU-hour (a weighted average of the lease rates across GPU types). For xAI, what was a "cluster from hell" for training has become a "golden goose" minting $5–6 billion in annual revenue when redeployed for inference. Elon's genius, I would argue, lies not in the model but in this asset-rotation structure.

    The weight of that $6 billion becomes clearer when set against xAI's income statement. Annualizing xAI's 1Q26 net loss yields roughly $6 billion in losses per year. The $5–6 billion in annual revenue generated by leasing Colossus 1 to Anthropic, in other words, almost perfectly hedges xAI's loss figure. This single deal effectively pulls xAI to break-even.

    Heading into the SpaceXAI IPO, this functions as a core line of financial defense. From a cost-of-capital standpoint, if the image shifts from "research lab burning cash" to "infrastructure tollgate stably printing $6 billion a year," the entire tone of the offering can change.

    DZODZO: Poradne distribuovane uceni (inference je snadna) asi jeste ani konkurence tak uplne nema, i kdyz jako vzdy najit nejake jasne informace je problem. Ale pokud to teda bereme, ze SpaceX ma centralizovany monolit a ostatni to maji distribuovane, tak pak to znamena, ze xAI je jeste mnohem vic v haji, protoze vyuzit rozumne jedno velke datove centrum je mnohem snadnejsi nez distribuovany system. Pokud v tom snadnejsim pripade maji xAI jen 11% a konkurence v tom slozitejsim pres 40%, tak to je velmi spatne.

    DOKIS: presne tak to je naopak ten "monolit v jednej lokalite", distribuovane su napr. openai rozlezle v datovych centrach microsoftu po celom svete

    PES: porovnavas 2 rozne riesenia clusterov, jeden je monolit v jednej lokalite, druhe je distribuovany system, obe riesenia maju svoje pre a proti v specifickych pripadoch pouzitia, skalovanie by som tu ako problem nevidel, naopak mi pride, ze nasadzuju hardware rychlejsie nez stihnu optimalizovat software

    Tak něco pro kompenzaci KOUDYho tapetování a nekritické adorace "génia 5D šachů" (a realistický pohled na to proč tak rád předává kapacitu vedle) :-)

    Muskova xAI dokáže využít pouze 11 procent kapacity svých datacenter pro AI. Firma provozuje 550 tisíc grafických karet Nvidia (hlavně H100 a H200), utilizace je ale problematická. Problémem má být softwarová infrastruktura a špatné možnosti škálování. Google a Meta prý vytížení zvládají na 46 a 43 procent. Musk se chce dostat na hodnotu 50 procent.
