Morgan Stanley's wealth management division successfully implemented GPT-4 to transform their vast institutional knowledge base into an instantly accessible resource for their financial advisors. The system processes hundreds of thousands of pages of investment strategies, market research, and analyst insights, making them immediately available through an internal chatbot. This implementation demonstrates how large enterprises can effectively leverage LLMs for knowledge management, with over 200 employees actively using the system daily. The case study highlights the importance of combining advanced AI capabilities with domain-specific content and human expertise, while maintaining appropriate internal controls and compliance measures in a regulated industry.
