Why this formula appears here
Whether the open-weight ecosystem consolidates around a handful of dominant families or stays fragmented across many providers is not a third axis; it is what the other two jointly produce. Write O(t) for a stylised index of how close the strongest open-weight models sit to the closed frontier — Axis A’s own proxy, anchored in the Epoch and Artificial Analysis readings above [ 1 , 4 ] — and W(t) for the share of open-weight releases operating under standardized external governance: a regulatory regime that reviews them the way closed deployment is reviewed, or a licence that is genuinely OSI-compatible rather than bespoke [ 16 ] . Reaching and holding a position near the frontier takes…

K(t) stays low however high either term climbs alone. Axis A determines whether O(t) can plausibly clear within this article’s horizon; Axis B determines whether W(t) can. Neither can be inferred from the other, which is why they are kept as two axes rather than folded into one — and why a narrowing capability gap sitting beside a licensing and regulatory picture that is still openly split, as documented above, does not yet settle which way the ecosystem’s structure moves.
