Which key answers this model

Your request → your own keys first (none added yet). The provider bills you; AnyRouter adds $0.

If none of your keys can serve it → the shared pool: keys other people donated. You pay the list price from AnyRouter credits. A donor whose key stays valid pays nothing here.

Pool for this model: not covered yet.
