GitHub Copilot's First Usage-Based Billing Cycle Closes and Developers Report Bills Jumping from $29 to $750

My take: This one stings a little, not because it is surprising, but because it was completely predictable. GitHub Copilot flipped to usage-based billing on June 1, and today the first cycle closes. Developers started posting screenshots: from $29 a month to a projected $750; from $50 to $3,000 in heavy agentic workflows. So the 'same base price, pay for what you use' plan turned out to be your electric bill in the middle of August with the AC cranked to 60. For me, this reframes what AI-assisted development actually costs. Light Copilot users? Probably fine. Heavy overnight agentic runs? Ay 🙄. Calculating real ROI on AI tools is no longer optional.
