Walmart Current initiatives and Future Outlook
Walmart has been actively investing in several AI-driven initiatives to enhance its operations and customer experience. Here are the key areas of focus:
AI and Technology Investments
- Generative AI and AR Integration: Walmart has integrated generative AI into its search engine to provide more contextually relevant search results. This enhancement allows customers to search using broader queries, significantly improving the shopping experience. For example, customers can search for “unicorn-themed toddler birthday party” instead of separately searching for individual items like plates and streamers. This initiative is part of Walmart’s broader strategy to make shopping more efficient and personalized (Walmart Corporate News and Information) (Analytics Vidhya).
- AI-Powered Customer Experience: Walmart employs AI in search and discovery, customer care automation, and associate-facing applications. Machine learning models predict customer preferences, enhancing product recommendations, while natural language processing helps automate customer service interactions, such as tracking orders or finding items in-store. These AI applications are designed to optimize both online and in-store shopping experiences (AIM Insights).
- Robotic Automation in Stores: Walmart is using robotic scrubbers equipped with cameras in Sam’s Club stores to monitor shelf inventory and verify pricing. These robots use deep learning technologies to manage stock levels and ensure accuracy in product placement, thereby streamlining inventory management (AIM Insights).
- Collaboration with Microsoft: Walmart collaborates with Microsoft to incorporate large language models from Azure OpenAI, aiming to enhance both internal and customer-facing AI applications. This partnership emphasizes responsible AI use, ensuring transparency, fairness, and trust in AI deployments. Walmart’s approach includes rigorous pre- and post-deployment testing to prevent model drift and mitigate bias, especially in applications affecting human resources and customer interactions (SiliconANGLE).
Micro Fulfillment Centers and IoT

These centers leverage advanced robotics and AI to automate picking and packing processes, significantly reducing the time required to fulfill online orders. The use of IoT devices in these centers further enhances efficiency by providing real-time data on inventory and operations (Walmart Corporate News and Information).
- IoT and Robotics: The integration of IoT devices and robotics in Walmart’s supply chain allows for more efficient and accurate operations. For instance, IoT sensors monitor the condition of products during transport and storage, ensuring quality and safety. Robotics, on the other hand, automate repetitive tasks, freeing up human workers for more complex and customer-facing roles (Analytics Vidhya).
Walmart AI Center of Excellence (COE)
In 2023, Walmart’s AI Center of Excellence (COE) continued to drive innovation by focusing on scalable customer-centric solutions. The COE facilitates the deployment of state-of-the-art machine learning models and AI-driven tools across various aspects of the business. This includes developing advanced algorithms for better demand forecasting, personalized marketing, and enhancing supply chain logistics.
