Walmart is internally promoting an AI programming assistant called Code Puppy. Business Insider reports that the tool has already gained significant use within the company, focusing not only on improving development efficiency but also on allowing teams to switch between multiple model vendors.
Supports multiple model accesses
Code Puppy was developed by Mike Pfaffenberger, an engineer on Walmart's global technology team. According to public descriptions, it can perform tasks such as writing code, modifying code, testing, and project analysis based on natural language commands, and its functionality is similar to Claude Code and Codex.
Unlike most similar products, this tool is not tied to a single model service provider. The project's public page shows that it can access dozens of models from multiple vendors such as OpenAI, Anthropic, and Google, allowing developers to switch between them, compare results, or call multiple models simultaneously to process tasks.
Balancing Costs and Control

This design primarily addresses cost management. If a provider raises the token price or tightens the call frequency, the team can quickly switch to other models and distribute different workloads across multiple service providers to alleviate quota and cost pressures.
Another consideration is code control. The report mentions that as AI programming tools accelerate software generation, enterprise codebases are also expanding rapidly. If a large amount of code is generated by a single tool, enterprises may continue to rely on the same service for maintaining, updating, and understanding this code in the future.
Walmart emphasizes platform neutrality
In a speech at the end of April this year, Pfaffenberger stated that this tool allows teams to retain control over their internal systems and development processes, rather than being tied to a single vendor. A Walmart spokesperson later also stated that the company maintains platform neutrality when building its tools to select appropriate partners and capabilities within the industry.

According to reports, the initial version of Code Puppy was completed in just a few hours, and it has since continued to iterate on its own. Dave Glick, senior vice president of Walmart, previously stated on LinkedIn that the tool's use has expanded from engineering teams to technical management and store managers, for creating simple automation tools and validating new ideas.
