Language of output

Hi there,

I’m trying to summarize Japanese sentences by inputting them into Playground and adding “Tl;dr” at the end.

Sometimes the response summary is in Japanese and sometimes in English,
What is the reason for this?

Even if the parameters and sentences are exactly the same, the language of the response changes depending on the timing.
It is the same even if you execute the API and get the result not only in Playground.
The accuracy of summarization is good regardless of the language of the response.

Any suggestions?
I’m thankful for every hint.
