PromptXpert: The AI for Better Answers

The burgeoning field of Artificial Intelligence (AI) and Large Language Models (LLMs) has profoundly amplified the importance of prompt engineering. However, prevailing manual and automated (APE) methods continue to grapple with significant challenges, including inefficiency, a notable lack of transparency, and burdensome computational demands. This paper introduces PromptXpert, a novel theoretical layered architecture meticulously designed to surmount these limitations. It offers a holistic and integrated solution for advanced AI prompt optimisation, systematically refining prompts through a multi-layered process.
