the big frontier models already have all laws, regulations and cases memorized/trained on given they are public. the real advancement is in experts codifying their expertise/reasoning for models to learn from. legal is no different from other fields in this.
So, fine-tuning the model to the law of the exact country. Or fine-tuning the model to the problem space of the exact codebase/product. You hire 10 law experts instead of 100. Or you hire 10 programmers instead of 100. Expertise is becoming a commodity I'm afraid.
