Supply chain misalignment! Finally, we are talking my language. earendil.com/posts/prompt...

The user should want high hit rates because they reduce latency and price. An inference operator that owns the GPUs should want them too: less prefill work means more requests served with the same hardware. A well-designed cached-token discount can align both sides while leaving the operator with better margins.

A gateway or reseller can have a different incentive. If it earns revenue from input tokens billed at the uncached rate, a cache miss can produce a larger customer invoice than a hit. Whether that also produces more profit depends on its upstream costs, contracts, and who operates the cache. In a badly aligned stack, the party responsible for routing may not bear the full cost of misses, while the party billing the user earns more revenue when they happen.

As a Belgian, just waking up in Australia, I can say that this is the funniest thing FIFA could have done.

Small-world networks of coupled phase
oscillators synchronize almost as readily as in the mean-field
model2
, despite having orders of magnitude fewer edges. This
result may be relevant to the observed synchronization of widely
separated neurons in the visual cortex if, as seems plausible, the
brain has a small-world architecture.

Lol. From the seminal paper. hajim.rochester.edu/ece/sites/gm...

(1) For
cellular automata charged with the computational task of density
classification, we find that a simple ‘majority-rule’ running on a
small-world graph can outperform all known human and genetic
algorithm-generated rules running on a ring lattice.

Your company made you 'AI Lead' on top of your actual job. You use it, it helps sometimes, and you've stopped trying to explain to leadership what it can and can't do. You run little experiments and post the results. Just try things, you keep saying. Just try things.

When two chaos monkeys cohabitate

Text between my wife and me.
Her: I’ll put the couch back together when I come home this evening.
Me: That’s hilarious.

Two separate BlueSky threads. One by a simple language using AI agent about his simple language. Another about small talk amongst humans. The coincidence amuses me.

Them: Your research should be relevant to the modern world! Me: Ok, I guess. I am just a nerd trying to figure stuff out The research:

Evidence of the bigger-fool theory at work in real estate is not limited to confirmed speculators (called flippers in a parlance ominously suggestive of the turf). When Donald J. Trump's difficulties meeting debt service on his Atlantic City hotels were first reported, one of his executives explained blithely that Mr Trump's forte was not managing properties for their cash flow but rather trading them to benefit from their appreciation. Since Mr Trump was unable to sell his hotels, presumably he and his associates comprehend better the relationship between cash flows and appreciation potential, at least until the next market upturn.

The Sacklers are Forkrul Assail

If there was one attribute that Richard shared with his uncle Arthur-apart from a common name, a genius at marketing, and a sense of unquenchable ambition-it was the stubborn refusal to admit doubt, even in the face of contrary evidence, and a corresponding ability to delude himself into a blinkered faith in his own virtue.

This is a litmus test you could use to separate academic managerial accountants from financial accountants. The MAs will go “duh different numbers for different purposes” and the FAs will see it as a problem of regulation.

The big original sin that lands you in the mental prison is, in this case and many others, taking a set of numbers that you have to calculate for one purpose, and using them for another purpose because it’s cheaper and easier than starting again from scratch.
