A startup with limited engineering resources and a tight budget wants to use a large language model for a wide variety of frequently changing tasks, such as drafting marketing emails, summarizing customer support tickets, and generating simple code. Evaluate whether they should prioritize developing a workflow based on providing examples directly in the prompt or invest in creating specialized, fine-tuned versions of the model for each task. Justify your recommendation by discussing the implications for accessibility, speed of adaptation, and overall resource management.
