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.
I also have plans for generating Portuguese contents, and yes they are also quite poor on translating, even worse when we’re talking about European Portuguese. I’m considering using specialized models for translation, such as Argos translate, but I didn’t test it yet, I’m poor in hardware resources and this is a pet project.
