My personal and subjective experience is that English is usually better than Spanish (my native language). Unless I'm asking something specific about Spain such as laws, history, etc. I always use LLMs in English.

I hear a lot from people around me, Koreans, that LLMs are mostly underwhelming. These days I hear that less and less, but what I recommend is to use English.

A simple array of English words is often better than a full, well-written Korean sentence(s).

Most of my italian friends, prompt in Italian and they claim no degradation.

Are there some hard numbers on the latest models?

Am I not seeing most of the article?

On the content: speakers of a single language don’t realise this is the case, although they’ve always known that non-English countries tend to get worse service in general in software (like Siri voice, or speech recognition (and if you speak a minority language of your country, even worse), map services, or sometimes just the LLM answering with US customary units that you don’t understand nor expect, etc.)
