Walmart’s AI workflows meet the realities of the balance sheet
Code Puppy
Walmart's internal AI assistant Code Puppy, previously open to 2.1 million employees for spreadsheets and presentations, now enforces strict token limits as LLM costs shift to pay-per-use. The retailer balances productivity gains against rising inference expenses, steering staff toward high-value AI tasks while keeping access to multiple company-funded platforms.
Anthropic launches Claude Fable 5.1 and says it’s up… It’s not FAANG anymore. It’s MANGOS.
The change in internal policy is a cost control measure, as LLMs are increasingly transitioning to pay-per-use, rather than the fixed-price, subscription model that gave near-limitless access to AI inference. Walmart has roughly 2.1 million employees, so even modest per-employee queries and task requests can create significant costs.
Walmart’s guidance to employees is to use AI where it can create value, and comes with guidance on how workers should choose the right AI tool for any given task. Reporting also says employees have access to other AI platforms paid for by the company.
Walmart has expanded AI tool use in the company and provided training for its employees in how to use an AI, encouraging workers to experiment and adopt successful uses. Now the costs of each interaction are being billed directly, it’s among other large enterprises struggling to balance reported improvements in productivity with the cost of achieving the same.
At least part of the issue may stem from the methods used to measure productivity in workflows based on AI. Previously, tracking the number and complexity of uses of AI tools as measure of productivity has led to many employees ‘gamifying’ their KPIs – so-called ‘token maxxing’. As recently as April this year, a partner at Sequoia Capital told The Wall Street Journal, “We all should be tokenmaxxing”, an approach that resulted the emergence of AI leaderboards in companies to celebrate those making best use of AI software.
Such performative practices at companies will increasingly incur costs relative to the number and complexity of AI tasks, and the model chosen to perform them. Larger models that perform recursive actions (‘thinking models’) use more tokens to process inputs introspectively, leading to higher bills for users. Walmart’s encouragement of workers to choose their model carefully is an attempt to limit spending on expensive, frontier models to achieve relatively trivial tasks, such as spreadsheet analysis and creating presentations.
Multi-agentic AI work may also create unexpected costs for employers. When employees instigate iterative loops running on multiple agents in order to create a desired outcome, the real cost of sub-optimal results (and the necessary refining and re-submission of prompts) is now measurable in hard cash.
While not all AI providers have changed the entirety of their billing models from fixed subscriptions to per-token, both Anthropic and OpenAI have already moved their higher tier enterprise plans to the new footing. Microsoft’s decision to charge for its GitHub Copilot software development tools as of June 1st is in line with what is rapidly becoming the new financial normality for model providers. Uber recently revealed that it had used up its 2026 budget for AI spend in the first four months of the year; a testament to changes in charging policy affecting end-users.
By setting limits on token use on a per-employee basis, Walmart is striving to keep a lid on its ongoing costs, enforce more thoughtful use of AI tools, and enable it to establish the metrics of return on investment in AI.
