LLMs were -in part- designed as translation tools. It's one thing they do really really well.

https://arxiv.org/html/1706.03762v7 (Attention is all you need) "Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train."

Ok, looking that up, that was quite literally one of the main design goals.

And they're really quite good at translating between the languages I use. They're the best tool for the job.
