The Translator charged less than it should have. The words the AI model wrote were priced at the lower rate for the words it reads, and a translation for which the AI provider reported no usage was not charged at all. Each translation, typed or spoken, is now priced the way a chat message is, from the model's own rates for what it reads and what it writes. Translations therefore cost more than before. When the provider reports no usage, the translation is charged on an estimate of its length.
