Microsoft executive Jay Parikh told employees to stop tokenmaxxing and introduced division-level AI token budgets. The company switched to cheaper OpenAI GPT-5.6 as its default model after new filings revealed OpenAI accounts for roughly 70% of Microsoft's AI revenue at $24.1 billion annually.
Microsoft Introduces Division-Level AI Token Budgets
Microsoft has introduced formal AI token budget targets at the division level, marking a significant shift from its earlier push for widespread AI adoption. In an internal email obtained by 404 Media, Jay Parikh, executive vice president of Microsoft's CoreAI engineering group, told employees that "tokenmaxxing is not what we are optimizing for."

As of July 2026, every Microsoft division now has an AI token spending cap, and employees can track their individual AI usage through an internal dashboard. Many engineers have been spending hundreds to a few thousand dollars a month in tokens.5
The company is making OpenAI GPT-5.6 Sol its default model for internal use to "get greater value from our token investment."

Parikh instructed developers working on AI coding projects to default to OpenAI's flagship GPT-5.6 Sol when working in the GitHub Copilot coding tool, and use that model most of the time.3
This shift places Microsoft squarely in a pattern where companies including AT&T, Meta, Uber, Walmart, and Amazon began capping or throttling employee AI spending after discovering that token-priced tools behave differently than seat-based software licenses finance teams know how to budget.5
OpenAI Accounts for 70% of Microsoft's AI Revenue
A new filing reveals the extent of Microsoft's dependence on OpenAI. Microsoft booked $24.1 billion in revenue from OpenAI during the year to June, Bloomberg reported.

By Bloomberg's estimate, OpenAI represents roughly 70% of Microsoft's actual AI sales. Microsoft disclosed this figure in a filing last week, providing the clearest picture yet of its AI business composition. Much of the $24.1 billion is OpenAI's own compute bill for cloud computing and model building costs, routed through Microsoft Azure and booked as Microsoft income.4
Against Microsoft's total revenue, OpenAI shrinks to under 10%, closer to 7%. The concentration only becomes apparent when narrowing the lens to the AI unit specifically. Microsoft holds intellectual property rights to OpenAI's models through 2032, and pointing its own engineers at OpenAI GPT-5.6 Sol squeezes more value from that stake.

The End of Tokenmaxxing Era
Tokenmaxxing is the practice of using as many AI tokens as possible, treating volume as proof of productivity. A token is the basic unit used to process and bill for the input and output of AI models.

For a time, tech employees were encouraged to use AI as much as possible, but that activity resulted in huge bills for companies.1
Parikh emphasized in his email: "I want all of us focused on maximizing outcomes that move the needle for our customers and our business. As such, we are updating our internal guidance and managing token spend with the same discipline we apply to every other critical resource."

This represents a shift toward cost-conscious AI development, where efficiency in AI spending is becoming increasingly important across corporate America after a brief era when developers were encouraged to run up large token bills without worrying about their output.3

Microsoft is not alone in confronting the economics of AI usage. Companies like Amazon, Adobe, Atlassian, and Citi have also cracked down on their employees' token spending.

Per-token prices have fallen roughly 98% since late 2022, but enterprise AI bills have still tripled because agentic tools consume dramatically more tokens per task than the autocomplete interactions that shaped the original pricing models.5
For the large hyperscalers, Wall Street is starting to demand more from their massive AI spending commitments, with capital expenditures from Microsoft, Amazon, Alphabet and Meta expected to top $700 billion collectively this year. Across the group, free cash flow dwindled in the latest quarter, and even went negative for Amazon and Alphabet. Microsoft's cash generation fell by 23% from a year earlier.

What This Means for Microsoft's AI Strategy
Microsoft has built its own MAI models and offers cloud customers more than 11,000 models. It has reached for alternatives including a $5 billion bet on Anthropic. GitHub Copilot alone, now past 50 million users, serves models from Anthropic, Google, Moonshot, xAI, and Microsoft itself.
4
Yet the filing shows roughly 70% of AI revenue still traces to OpenAI, suggesting efforts to spread the risk have not moved the number that matters.One anonymous Microsoft staffer told 404 Media: "This really feels like the ultimate admission that we, as hosts of AI infra, can't afford our own AI products. And if that's even partially the case, how could the companies we sell it to manage?"
2
However, Microsoft does not appear to be seeking an overall reduction in token use—it wants to be an AI-first company. It simply wants more bang for its buck, treating AI tooling more like a utility bill than an enterprise software subscription.5
Watch how Microsoft balances its internal AI token consumption against customer expectations, and whether other tech giants follow suit with similar usage-based billing restrictions. The shift from unlimited AI adoption to metered infrastructure may signal that the enterprise AI market is moving from an experimental phase into a procurement discipline where every token has a price tag and every division has a ceiling.
