Shaping the Future of Banking with AI : Distilling and Optimizing Large Language Models for AI Assistants in Finance and Banking

The integration of financial services with technology has created an overwhelming amount of structured and unstructured data. To turn this into reliable, real-time intelligence, we need efficient and well-optimized language models, not just raw scale. Swissquote's Data Science team offers an internship focused on

distillation, fine-tuning, and parameter-efficient adaptation (e.g. LoRA)

of Large Language Models (LLMs) for production-grade AI assistants. The main objective is to explore, design, and refine model compression and adaptation techniques to build

fast, cost-efficient, and robust

AI assistants tailored to the banking and finance domains.

The DS team is integrated into Swissquote's core research group, the Quantitative Research & Solutions (QRS) department, specialized in theoretical and applied research in Quantitative Finance and Data Science. QRS's mission is to provide best-in-class quantitative and AI solutions by performing research to support every division of the bank in need of an analytical and data-driven approach.
