Prompt Engineering for LLMs: Real-World Applications in Banking and Ecommerce
Balkishan Arugula · International Journal of Artificial Intelligence Data Science and Machine Learning · 2025
Big Language Models (LLMs) like GPT have revolutionized computer understanding & creation of human language, therefore generating fresh possibilities in AI-driven problem-solving. As these models develop, timely engineering formulating precise & efficient input prompts has become more important in realizing their full potential. Rapid engineering allows users to guide current models to perform domain-specific actions which are improved by their accuracy and relevance, therefore enabling rather than ground-up development of the latest models. In industries like banking & e-commerce, where complex decision-making processes & huge volumes of unstructured information call for intelligent automation, this approach is showing notable change. Quick engineering helps banks to produce automated reports, identify more intelligent fraud & provide better customer support using natural language interfaces. Prompts are being used by e-commerce systems to improve their product recommendations, personalize shopping experiences, and maximize supply chain communications. These improvements are not merely technical ones; they also change operational effectiveness & also customer experiences. Many actual world case studies show the effectiveness of this approach: for instance, an online retailer improved conversion rates by AI-driven content personalization enabled by careful prompt design, while a financial institution used LLM prompts to greatly lower customer query resolution times. A key difference will be the ability to proactively affect LLM results by quick engineering as companies progressively use artificial intelligence technology. This abstract highlights the need of understanding the nuances of fast design to link broad artificial intelligence capabilities with tailored commercial solutions, thereby transforming complex language models from not only powerful but also quite useful
