Walmart is leveraging its vast data to develop a retail-specific AI model, integrating with GPT-4 for enhanced natural language understanding. With nearly two dozen applications in place, including a chatbot for customer support, the company aims to evolve from basic task-based interactions to predictive, problem-solving capabilities. The goal is to anticipate customer needs, potentially suggesting items like allergy medications based on individual circumstances, all while ensuring a responsible approach to this advanced technology.
