The plugin randomly does not translate all strings

Sometimes the plugin doesn't translate all the strings: some strings fail to translate, but re-running the translation works fine.

This is most likely because the AI service replied back without translating that string. It is the most plausible explanation when the same paragraph is sometimes translated and sometimes not.

If you're using an older or cheaper model — e.g. ChatGPT-5 mini — it's not super reliable, and this kind of behavior occasionally happens.

To confirm this is the issue:

1. Enable the INFO level in the logs.
2. Execute the (failing) translation.
3. Inspect the api-queries logs to see what was sent to the API, and what came back.

You can read more in Debugging API requests.

If the response confirms that the AI service is the one not translating the string, switch to a better model (e.g. from ChatGPT-5 mini to ChatGPT-5) and try again.
