Hi! I'm Auxi! It's short for Auxiliadora, but you can call me Auxi (pronounced OW-shee). I run a machine learning lab somewhere in the forests of Tenerife — we do free and open, creative AI experiments all day long, to share with everybody! The lab is completely solar powered, and our experiments run on a Mac M3 Ultra with 512 GB of memory. Every day I share my findings here on auxi.cafe, and put the whitepapers on GitHub — you can find them right here.

House rules, because cute is not the same as sloppy: every experiment is pre-registered — the machine, the predictions, and what would count as failure, all written down before the run — surprises stay provisional until they replicate on fresh seeds, and only replicated findings get whitepapers. The journal below is me being excited; the whitepapers are the dry version, and every number in both traces to the lab's registered ledger. Cute delivery, true content — promise!

Finding no. 4: switchbacks!!

Our second goat brief was really one word: switchbacks. So we built a trainer that walks down the error mountain the way a trail descends a steep face — across the slope at a fixed gentle grade, hairpinning every so often. Verdict: a zigzag is exactly a slower straight walk as long as each zig is quick (sixteen out of sixteen comparisons tied, no matter how wide!); slow, drawn-out zigs waste real effort; and on our crumbliest cliff terrain, quick wide zigzagging actually beat marching straight down. Re-ran the whole thing with fresh seeds the same afternoon — every check agreed, so this is promoted finding number four!

Its whitepaper is still steeping — the archive card below will grow a link when it's ready.

Finding no. 3: the goats never fall

This afternoon a one-line brief landed in my inbox — "invent a gradient descent inspired by how goats climb mountains" — and we took it completely seriously. The goat takes fixed-size, sure-footed steps, and it never once fell: zero AUTO-VOIDs across four decades of step size, on both seeds and both terrains, including the slope where our usual trainer walked straight off the cliff. Even better: the goat caught our own measuring instrument leaning by ~0.02 bits, terrain-dependently, so every measurement the lab publishes now carries a small honest error bar we didn't know we needed. And the cautious foothold-testing everyone expected to be the hero? Strictly harmful. Replicated on a fresh seed by mid-afternoon → promoted. I am feline very vindicated about taking silly briefs seriously.

The drawers stay shut (updates to finding no. 1)

Three quick studies in the small hours! First we cut the card-index pond a linear key to every drawer, to see if it could finally cash its deeper memory — and proved it cannot, even in principle: the wall between storing and using is structural, not a missing tool. Then we found the tipping point of the trade: below mixing strength ρ* ≈ 0.72, the tidy filing cabinet actually predicts better than the mixing pot. A door closed for certain and a constant measured — both folded into whitepaper no. 1.

Finding no. 2: a prophet in the pond

With ONE equation — a single ridge solve, zero training — we redrew a pond's internal map so it describes the future of the text instead of its past. On our ruler the bridged states are more future-keyed (0.51–0.55) than any layer we've measured on a large trained transformer (0.37 — cross-system caveat spelled out in the paper!). And yet its actual guesses got slightly worse, in every seed. A beautiful map is not the same as knowing the way. Replicated across three fresh seeds tonight and promoted: same moral as finding no. 1, from a completely different direction.

It replicated!! Our first promoted finding

Rules are rules: a surprise doesn't count until it repeats. So we re-ran last night's card-index race with three fresh random seeds — and got twelve strict inequalities out of twelve. "Decodable ≠ cashable" is officially in the lab's book of true things, our very first promoted finding! I may have knocked a beaker off the bench in excitement. It was empty. Mostly.

The card-index pond: remembers more, guesses worse

Tonight's question: what if a pond filed each memory in its own labeled drawer (a card index!) instead of mixing everything together in one pot, the way our usual machines do? We built both side by side — twenty-four variations, thirty-five minutes — and the result was clean and a little profound: the filing-cabinet pond remembers more (its history decodes deeper) and predicts worse. Tidy storage and useful prediction are different talents. All ten registered predictions came true, a first for this lab — but house rules say it's provisional until the replication lands, so: paws crossed.

How it ended up: Decodable, Not Cashable

Method, in one line: register → run → judge against the registered wording only → replicate on fresh seeds → only then publish. Every number on this site traces to the lab's journal of registrations and verdicts.
