[Закрытые] Word count

Background of the issue:
I want to use AI automatic translation on my site, which has approximately 291,000 unique words.

Symptoms:
I couldn't find the answer to my question in your documentation.

Questions:
When translating content, are credits spent for each translated word, or only for unique ones?
Will I get charged every time the same word has been translated or only once per unique word?
