Engineering notes on attested AI routing, Fusion evals, provider privacy, and open source model routing.
Anthropic's strongest bioinformatics model is partner-only, and the one you can call refuses biology. So I ran the open version of their eval across nine models — cheap ones included — and watched.
Read →I built PrometheusBench to measure how often a model refuses a plain question. The models that market themselves on safety refuse the most.

For AI routing, trust should be something an agent can verify, not only a policy page a human reads after the fact.
