GitHub announced that every Copilot plan moves to usage-based billing via "AI Credits" on June 1, 2026. The flat-rate model is dead. Every plan gets a monthly credit allotment calculated by actual token consumption (input, output, cached) at listed API rates. Code completions and Next Edit suggestions stay unlimited and free, but everything else now has a meter running.
The tell: starting April 20, new sign-ups for Pro ($10/month), Pro+ ($39/month), and student plans are paused until the transition completes. GitHub is locking the doors while they rearrange the furniture. That's not confidence. That's damage control.
This connects directly to what's happening at Microsoft's broader level. Nadella initiated a "Copilot Code Red" on April 18 after analysts flagged that only 15 million of 450 million Office users pay for AI features. A 3.3% conversion rate. The new "E7 suite" launching May 1 with Agent Mode and Copilot Cowork is the response. Microsoft is repricing everything in its AI stack simultaneously, from the OpenAI partnership down to individual Copilot seats.
What should you do? First, don't panic. If you're a light Copilot user (tab completions, occasional chat), you'll probably come out even or ahead. The unlimited completions carve-out protects the core workflow. But if you're a heavy user running Copilot Chat constantly, asking it to explain codebases, or using agent features extensively, you need to understand your token consumption before June 1.
Second, start tracking your usage now. CodeBurn, an open-source terminal dashboard I'll cover in the deep dives, can monitor your Copilot spend alongside Claude Code and Cursor. Get a baseline before the switch happens so you're not surprised.
Third, consider whether this changes your tool mix. If Copilot's economics shift, the calculus between Copilot, Claude Code, and Cursor shifts with it.
