Imagine signing up for an all-you-can-eat buffet, going back for seconds and thirds every day for two years, and then showing up one morning to find the restaurant has replaced the buffet with à la carte pricing — and your usual plate now costs forty times what you used to pay per visit.
That's roughly what happened to millions of software developers today.
GitHub Copilot's new usage-based billing system took effect on June 1, replacing flat subscription rates with token-based pricing — and the reaction has been swift, loud, and more than a little alarmed. One developer shared projections showing their bill jumping from $29 a month to $750. Another calculated a rise from $50 to $3,000. These aren't glitches or worst-case hypotheticals. They're the real math behind a billing model that, until today, most users never had to think about.
GitHub Copilot — owned by Microsoft, used by an estimated 4.7 million paying subscribers — has been the dominant AI coding assistant for the better part of three years. It sits inside the tools developers use every day (Visual Studio Code, JetBrains, Vim) and suggests code, writes functions, reviews pull requests, and increasingly operates as an autonomous "agent" that can take complex multi-step tasks and run them on its own. For most of that time, the pitch was irresistible: a flat monthly fee, starting at just $10, for an assistant that kept getting smarter.
That deal is now over. And the ripple effects go far beyond one company's pricing page.
Because what's really happening here isn't just a billing update. It's the moment the AI industry's open secret finally goes public: the "unlimited AI for a flat fee" era was always running on a subsidy. The bill has arrived — not just for Copilot users, but eventually for anyone who has grown used to AI tools that were, quietly, too cheap to be true.
