Walmart's technology team built and deployed a set of AI-powered tools to help software engineers work faster. These include a coding assistant called Code Buddy, an internal question-answering assistant called DX AI Assistant, and a diagram-generation tool called ArchiText. Walmart says these tools saved its developers around 4 million hours in a single year.
Details
The tools were announced in an October 2024 Walmart Global Tech blog post. Code Buddy helps developers write unit tests, understand existing code, and debug problems; AI-generated code goes through multi-stage checks for accuracy, security, and compliance before being accepted. The DX AI Assistant answers Walmart-specific questions about internal tools and systems, saving developers an average of 5 minutes per question. ArchiText converts a text description into a technical diagram called a UML (Unified Modeling Language) diagram 69% faster than doing it manually, saving approximately 31 minutes per diagram. Coding assistance has been deployed to engineers in North America and India. Walmart has also stated its goal of embedding generative AI into every stage of the software development process within three years.

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.
