Creative GenerationReplaces Human LaborVerified

Walmart uses generative AI to write and improve product descriptions and data for items sold on its website. The company used AI models to create or improve over 850 million pieces of product information — work that Walmart's CEO said would have required nearly 100 times as many employees to complete manually in the same time. Walmart also gives third-party sellers tools to generate their own listings using AI.

Details

The 850-million-item figure was disclosed by CEO Doug McMillon on the August 2024 earnings call. The system uses a two-step approach: one large language model extracts product attributes from existing descriptions and images, and a second large language model — fine-tuned on human-verified data — checks the accuracy of the first model's output. For third-party marketplace sellers, Walmart launched AI-powered listing tools at its August 2025 Marketplace Seller Summit, including single and bulk item setup tools and a "Smart Assistant." Sellers can use a generative AI tool in the Seller Center Success Hub to receive suggestions for product names, descriptions, and key features, all calibrated to Walmart's content standards.

Other practices by Walmart

OtherWalmart is piloting an AI tool that simulates a job interview for candidates applying to work at the company. It walks applicants through up to 10 practice questions, scores each response on a scale of 1 to 10, and gives instant feedback on how clearly and confidently the person answered. The pilot began in June 2025 with current Walmart employees and was planned to expand to all applicants.OtherWalmart delivers orders using drones and self-driving trucks that operate without a human driver. Drone delivery is available near 270-plus Walmart stores and is on track to reach 40 million Americans. In 2021, Walmart and an autonomous trucking company called Gatik completed the world's first fully driverless commercial delivery route, with no safety driver in the cab.OtherWalmart uses AI software to plan the most efficient routes for its delivery trucks, figure out how to pack trailers to minimize wasted space, and cut unnecessary miles from its logistics network. Walmart says this eliminated 30 million unnecessary miles and avoided 94 million pounds of CO₂ emissions. The company now sells this same routing technology to other businesses as a commercial software product.
