GitHub Copilot 定價調整：6 月起改採 AI Credits 按量計費模式

GitHub Copilot has expanded from a code-completion tool into an AI agent capable of running lengthy, multitask workflows, driving up token usage and inference costs. GitHub says some requests cost more to process than an entire month's subscription fee. That suggests fixed-price plans such as the $10-a-month Pro tier and $39-a-month Pro+ tier can no longer support heavy agent workflows while maintaining reliable service.

On April 20, 2026, GitHub paused new applications for Copilot Pro, Pro+ and Student plans, while Free remained unaffected. It also tightened session caps and token allowances calculated every seven days, with the Pro+ cap more than five times that of Pro. Pro users can no longer access Opus models, and existing paying subscribers may request refunds through May 20.
