Opus is usually $5/million input and $25/million output. The new fast mode is $30/million input and $150/million output!

The problem arises when the input graph is corrupted. Ranking algorithms are, for the most part, agnostic regarding the genuineness of trust. They faithfully process the signal they receive. If a malicious node (Node_X) is artificially connected to many nodes with high authority (even if that authority is itself fraudulently built), the algorithm will mathematically calculate that Node_X is important and trustworthy. Conversely, if a target node (Node_Y) is attacked by a coordinated network of bots (which the algorithm perceives as nodes with some authority because they are integrated into the corrupted WoT), its authority score will plummet.
