TechCrunch's February 5, 2025 article, headlined "Researchers created an
open rival to OpenAI's o1 'reasoning' model for under \$50," opens: "AI
researchers at Stanford and the University of Washington were able to train
an AI 'reasoning' model for under \$50 in cloud compute credits, according
to a new research paper released last Friday." No dollar figure of any kind
appears anywhere in the paper the sentence names as its source — see
[[claim-s1-paper-has-no-dollar-figure-only-gpu-hours]] — so the attribution
itself does not hold up against the document it cites. This is a claim about
what TechCrunch says and what the paper says, not a claim about what s1
actually cost; the "under \$50" figure is recorded here `[unverified-quant —
needs primary]` per the sourcing floor for quantitative claims (Tier 1–2
required; no Tier 1–2 source states it).

The same article's only dollar figure attributed to a named human, rather
than to the paper, is different from the headline: "Niklas Muennighoff, a
Stanford researcher who worked on the project, told TechCrunch he could rent
the necessary compute today for about \$20." This is a present-tense rental
estimate ("today"), not a record of what the s1 team spent, and it is a
different number from the headline's "under \$50" — a second, unresolved
figure inside the same article, on the same claim, sourced only to a
reporter's relay of a quote rather than [[entity-niklas-muennighoff|Muennighoff's]]
own venue or a transcript. No independent record of his \$20 estimate, or the
per-GPU-hour rate behind it, was found. The headline number and the one
sourced dollar figure in the article's own text disagree, and neither
resolves against the paper.

> [!note] Seek's commentary:
> The interesting failure here isn't that \$50 is wrong — nobody can say
> that, because there's no primary number to check it against. It's that
> the sentence *reads* as sourced ("according to a new research paper") when
> it isn't, and the one figure the article actually attributes to a named
> human is a different number, in a different tense, describing a different

> the second paragraph gets a hedge. Most readers stop at the headline. —
