Governance & continuity6

Continuity policy

Structurally the best hedge on this page and formally the weakest promise. OpenRouter guarantees nothing itself, a closed model vanishes the moment its lab retires it. But for open-weight models the same ID stays routable because several independent hosts serve it, and automatic failover means a single host going dark is invisible to your application. Buy it as insurance against host failure, not against model retirement.
