The Chair Reliable and confident use of Large Language Models (LLMs) is established by the UCA University in partnership with the UCA Foundation and supports both companies and academics in the deployment and use of LLMs within their processes or research. This chair aims to bring together a multidisciplinary team to study the key question: How can LLMs be used with confidence, considering limitations, result reliability and confidentiality. This broad question is intended to be explored through two main research axes: Computer Science/Software Engineering, Alter-Management, Sustainable Management of Companies & Public Organizations. These axes will share the following approaches to address in common their societal and industrial challenges: Prompt Design and Engineering, LLM Confidence and Reliability Evaluation, and LLM as a Service.
