## AI overview

This article explains that ChatGPT subscriptions and OpenAI API billing are separate systems on a shared account. ChatGPT uses fixed monthly or per-seat subscriptions, while the API uses pay-as-you-go, per-token metering that varies by model. It also covers prepaid credits, spend controls, rate tiers, and enterprise invoicing.
