GitHub is overhauling its billing for Copilot, moving to a usage-based model effective June 1, 2026. This significant shift from premium request units (PRUs) to GitHub AI Credits aims to align costs with actual compute and inference demands.
AI Credits Replace Premium Requests
Under the new system, every Copilot plan will receive a monthly allocation of AI Credits. Usage is calculated by token consumption—input, output, and cached tokens—using API rates specific to each model. This change is framed as essential for maintaining service reliability and sustainability as Copilot evolves into a more agentic platform capable of complex, repository-wide coding sessions.
This move affects how developers and organizations manage their AI coding assistant expenses.
