[counterintuitive] Fine-tuning is the best way to teach an agent a new custom behavior or format
Use few-shot prompting and clear system instructions first. Reserve fine-tuning for style/tone alignment, reducing latency, or distilling a complex prompt into a model, not for adding new factual knowledge.
Journey Context:
Fine-tuning is excellent for formatting and style, but it struggles to inject new factual knowledge \(it just adjusts weights, doesn't add a database\). It is also brittle—updating behavior requires a full retraining run, whereas updating a prompt takes seconds. RAG plus prompting is far more auditable and maintainable for dynamic behaviors.
