Your question is Fine-Tuning vs Prompted APIs. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are deciding how to adapt a large language model for a new application. One option is to fine-tune a base model in your own environment. The other is to use prompt engineering with a managed API.
Compare and contrast the trade-offs between fine-tuning a foundational model versus utilizing prompt engineering with a managed API.
