Modelkeel

AI products can break when a depended-on model is deprecated, price-changed, silently updated or made unavailable in a jurisdiction. Generic routers can redirect requests, but a successful response does not prove equivalent product behavior. Modelkeel monitors supplied availability signals, preserves the exact dependency policy and tests approved alternatives against a customer-owned golden evaluation set before proposing cutover. The supplied research confirms active routing, observability and evaluation products, yet finds no verified competitor combining jurisdiction-aware availability intelligence with evaluation-gated transition. Their subscriptions and service fees are observed market references, not fixed product pricing. The compounding asset is each customer's accepted evaluation history and dependency policy, although the routing layer is readily copyable. A published notice is a signal, not proof that access changed for every account; an evaluation pass is evidence against a defined suite, not assurance of universal equivalence. Signal receipt, source verification, policy match, evaluation execution, result, approval, routing command, provider acknowledgement, application readback, quality observation and rollback remain separate. The product can reduce uncontrolled dependency changes. It cannot guarantee regulatory interpretation, provider availability, semantic equivalence, zero downtime or correct business outcomes.
