There is no "honest" AI though. It is always biased towards its prompt and ultimately its training data.
Compare flights? You have to assume it is objective and not tainted by corporate bias or backroom deals(aka ads and sponsored content), unless you selfhost and find an objective model.
Search Wikipedia? You have to constantly check that it is giving you straight facts instead of being constrained by its community and safety guidelines.
The problem with so many of these usecases is treating AI as a super intelligent Vulcan who is always logical and objective aka Spock, when we are better off treating it as if it is a salesman.
