LLM Fine-Tuning vs Prompt Engineering for Consumer Products

Author(s) Rajeshkumar Rajubhai Golani
Country United States
Abstract This article examines the strategic considerations when implementing Large Language Models (LLMs) inconsumer-facing products, focusing on the comparison between fine-tuning approaches and promptengineering techniques. As organizations increasingly integrate these powerful AI systems into theirproduct ecosystems, they face critical decisions about implementation strategies that significantly impactperformance, cost structures, development timelines, and long-term viability. Fine-tuning offers domain-specific adaptation and improved accuracy for specialized tasks but requires substantial computationalresources and expertise. Prompt engineering provides flexibility, rapid iteration, and lower initialinvestment but may face limitations in specialized domains and scaling challenges at high volumes. Beyondthese core approaches, hybrid implementations combining elements of both strategies have emerged aseffective solutions for many consumer applications. Through analysis of implementation trade-offs andcase studies from e-commerce and content creation sectors, this article provides practical guidance forproduct teams navigating LLM implementation decisions, highlighting the importance of aligning technicalapproaches with specific business requirements and growth stages.
