GitHub Copilot moves to usage-based billing on June 1, 2025, and the individual plan math has already changed before launch. Pro subscribers get $15 in total monthly usage for $10, Pro+ gets $70 for $39, and the new Max tier delivers $200 for $100. Each plan splits that total into a fixed base credit (equal to the subscription price) and a variable flex allotment on top. Code completions and next edit suggestions remain unlimited on all paid plans and burn zero credits.
The flex allotment is the mechanism worth understanding before you commit to a tier. GitHub is explicitly reserving the right to adjust it over time as model pricing and efficiency shift. Your base credits are locked to your subscription price and will not change. The flex portion can. This distinction matters most for Pro+ and Max users doing sustained agent work, where a $31 or $100 flex buffer could shrink if underlying model costs move. The original announcement underestimated how quickly agentic, multi-step tasks would eat through allotments, which is why these numbers were revised before the billing switch even happened.
No action is required for existing monthly Pro or Pro+ subscribers. The updated allotments apply automatically on June 1. The new Max plan at $100 per month targets high-volume users who need headroom beyond what Pro+ provides. GitHub's full billing docs cover how the base-first drawdown works across IDE, github.com, and CLI. Read them before you hit an overage.
