and use normal chat completion api is also work:

"messages":[{"role":"user","content":"please translate the following title to Japanese:'Intel claims Panther Lake will achieve 5x performance increase'"}]}

but when use API function calling，gpt always return the origin title， and never do what i want to do.

In your API call: tools or functions - you have to pick just one.
