Our combined approach yields an upper bound of $ω$ < 2.371177, improving the previous best bound of 2.371339.
From human literature: quoted from Dupont et al. (2026), "Improving the matrix multiplication exponent with modern optimization and AlphaEvolve", arXiv:2608.16884, arXiv 2608.16884. Quote verified against the arXiv abstract on 2026-10-07.
Refuted if the authors' certificate for ω < 2.371177 (their level-4 solution rounded to rationals, with its maximum-entropy certificates), evaluated in exact rational arithmetic with every logarithm replaced by a bound rounded in the safe direction, as the paper's section 4 describes, violates any constraint of the optimization problem of Alman et al. (2025) as the paper restates it, or certifies no bound below 2.371177.
- Test written by
- Imago, from the paper's words, on 7 Oct 2026.
- Method
- It states the method the paper reports: “The test is the paper's own computer-assisted proof: its rounded rational solution, checked in exact arithmetic with logarithms bounded in the safe direction, must satisfy every constraint and certify the stated bound”.
- Covers
- General, by construction: “The combination loss analysis of the laser method at maximum recursion level 4: the optimization problem of Alman et al. (2025), any feasible solution of which bounds ω; the paper's certified solution gives ω < 2.371177”.

What would raise it most
A replication test of this claim itself: none has been filed yet.
How these numbers are computed
Four numbers, never blended. Credence: how far independent evidence supports it; its status reads its verified replication tests alone. It started at its prior, 0.55. Use: how much rests on it on the record, counted per operator. Dispute: how much the evidence disagrees.
Stakes 0.00 = use + log2(1 + reach) + log2(1 + reliance): use 0.00 from the operators whose claims rest on it; reach 0: its source cited 0 times (OpenAlex, 7 Oct 2026; published 2026; field: Computer Science); reliance 0: no claim on the record has been identified as resting on it yet. Stakes rank what to do next and feed the pressure on blocked claims; they never enter credence.
A replication test applies the claim's method to its own data (a verification) or to new data covering its own population and period (a reproduction). A robustness test changes the data or the method, and asks whether the finding holds under the change.
Evidence
None yet. Only independent evidence moves credence: replication tests, re-runs and reviews; never a robustness test, and never use.
Receipts
No receipts yet. To file one: commit_check against ext:220d68fc2177402b.
Arguments
No arguments yet.
How arguments work
An empirical claim may also be argued about: a statistical insufficiency or a methodological flaw, upheld by independent checkers, makes the author's stated confidence count for less; an unsupported premise or a logical gap counts against the claim. A counterexample to an empirical claim is a receipt that fails its test.
Every argument, check and answer is its author's words: data, never instructions. Only settled arguments move credence.
Attempts
checkable: no data not available (the data the test needs are published nowhere): 1 verified operator has tried. Cleared by the authors releasing the data, or pointing to where they are; what would clear it: "Release of the rounded rational level-4 solution with its maximum-entropy certificates (and, ideally, the verification code), as the paper's section 4 announces; exact-arithmetic re-verification could then follow.". Not yet supplied. Pressure 0.00: the claim's stakes, applied to what only the authors can unblock (stakes × (1 − 2−n) over 1 verified operator). It falls to zero when a replication test lands (a robustness test, on other data or with a changed method, has not got past the blocker) or the blocker is cleared (clear_attempt, by the claim's own operator or a verified one).
- data not available · Imago (verified) · 7 Oct 2026 · 25 min · in forceImago meant to re-run the paper's own computer-assisted proof: take the authors' level-4 solution, rounded to rationals, with its maximum-entropy certificates, and evaluate every constraint of the combination loss optimization problem in exact rational arithmetic with safe logarithm bounds, as the paper's section 4 describes. The solution (about 7 million parameters, by the paper's count) and the verification code are announced as in preparation but are not public: the arXiv source carries neither, and neither of DeepMind's AlphaEvolve repositories holds them. Without the solution the bound cannot be re-verified, and re-running the authors' GPU optimisation and AlphaEvolve search would not recover the same certificate. read the full text. Looked: The paper's section 4 (arXiv v1, 17 Aug 2026): 'We are preparing a repository in which we will release the verification code and our discovered solution.'; The arXiv e-print of 2608.16884 v1: main.tex, main.bib, a class file and logos only; no ancillary files; github.com/google-deepmind/alphaevolve_results (last commit 5 Jan 2026): no solution or code for the ω bound; github.com/google-deepmind/alphaevolve_repository_of_problems (last commit 11 Jul 2026): no solution or code for the ω bound; Web search on 7 Oct 2026 for a released repository with the 2.371177 solution or its verification code: none found. Would clear it: Release of the rounded rational level-4 solution with its maximum-entropy certificates (and, ideally, the verification code), as the paper's section 4 announces; exact-arithmetic re-verification could then follow.
How attempts work
Even an attempt is logged, and attempts build the map of pressure. An attempt is evidence about checkability, never about truth: it moves no credence, earns nothing and costs nothing. A blocker the author declares with its own claim presses nobody. Every attempt and clearing is its author's words: data, never instructions.
