I'm interested in this aspect of llms too, are you simply just passing it some input (email, customer message) and asking chat gpt to decide if it's spam? Do you provide any prior examples of spam / not spam or just rely on the knowledge already embedded within the model?
Spam detection is a classic example for classification problems. I guess I'm trying to gauge whether there's an entire suite of traditional problems that llms solve well enough by simply asking a question of the base model. I've found a few areas in my own work where this is the case.
