Even the default example of "Hello, how are you?" from English to French yields an awfully wrong result ("Hello, what is your experience?")...
I wouldn't trust them for anything else.
The other models are not better, here's the text generation output from "I enjoy walking my cute dog":
> I enjoy walking with my cute dog, I have been going to the park, and I just happened to like walking with my cute dog. I like to play with the dog.
My dog (Hannah) has been on my way home since December and when she came home she told me to go out and stay back. I told her that she had been too busy. I had to start working and had to go outside and go see myself again.
It could be just an algorithm that generates random sentences that it wouldn't make less sense.
