BELLWETHR INFERENCE INDEX — BWI
$ 1.55
/ 1M tokens
METHODOLOGY IN DRAFT v0.1 AS OF JUL 31 2026

The index will track the USD price of a single inference token produced by any model that clears a fixed bar of capability on a standard benchmark suite. That bar — and the basket — are exactly what we're defining, in the open.

Help define
the standard.

An index is only as good as its method. Weigh in on the benchmark, the threshold and the basket — or submit the prices you actually pay.
