Portuguese is my mother tongue. I’ve tried ChatGPT, GPT 4, Claude, local LLMs, etc and they all produce inaccurate results that I still have to edit a lot. They also can’t remember well if a character is male or female. It feels like they all have the same capabilities as Google Translate, which as far as I know, isn’t an AI.
Claude 2 and gpt4 do a pretty good job for English to Italian and vice versa. Gpt3.5 seem a little more “robotic” for English > italian, but work fine with italian > English.
Obviously that’s only feeling…i haven’t done any objective test.
