Prices and credits in Quad Chat

API prices are the model provider's list prices per million tokens, shown for comparison only. Quad Chat plans have a flat monthly price and draw usage from shared credits, so you are not billed per token. Cheaper variants use fewer credits per message than frontier ones, so a plan's credits do not map to a fixed number of messages. Running out of credits does not lock you out: you can wait for the next period, upgrade, or buy a one-time credit pack.
