Advanced Applications of Generative AI in Actuarial Science: Case Studies Beyond ChatGPT
For actuaries and insurance practitioners, this provides concrete examples of GenAI integration, though the contributions are incremental demonstrations rather than breakthroughs.
This paper presents four case studies demonstrating generative AI applications in actuarial science, including improving claim cost prediction via LLM-extracted features, automating market comparisons with RAG, classifying car damage using vision-enabled LLMs, and migrating legacy R code to Python with multi-agent systems. The results show practical feasibility but lack quantitative performance comparisons.
This article explores the potential of generative AI (GenAI) to support actuarial practice through four implemented case studies. It situates these case studies within the broader evolution of artificial intelligence in actuarial science, from early neural networks and machine learning to modern transformer-based GenAI systems. The first case study illustrates how large language models (LLMs) can improve claim cost prediction by extracting informative features from unstructured text for use in the underlying supervised learning task. The second case study demonstrates the automation of market comparisons using Retrieval-Augmented Generation to identify, extract, and structure relevant information from insurers' annual reports. The third case study highlights the capabilities of fine-tuned vision-enabled LLMs in classifying car damage types and extracting contextual information from images. The fourth case study presents a multi-agent system that autonomously migrates actuarial legacy code from R to Python and validates the translation against the original code's outputs. In addition to these case studies, we outline further GenAI applications in the insurance industry. Finally, we discuss the regulatory, security, dual-use and fraud, reproducibility, privacy, governance, and organisational challenges associated with deploying GenAI in regulated insurance environments.
