System AI services use credits based on actual usage. Follow reading scoring does not. Your API provider bills usage of your own API separately.
Personal AI usage includes generation, review, retries and pre-generation, even if a task fails or its results are unused. Cached results and existing audio playback do not incur another generation charge.
