Cost is an estimate, not a bill. It applies current standard API prices per 1M tokens to the model recorded for each usage event. Unknown, local, experimental, and unpriced model slugs are excluded and pricing coverage is shown in the UI. Reasoning tokens are already part of output tokens and are not charged twice.
