GitHub Copilot Moves to Usage-Based Billing June 1 — Opus 27x, Sonnet 9x Multipliers
r/ChatGPT·high signal
GitHub quietly updated its Copilot pricing multiplier table, revealing Claude Opus at 27x and Claude Sonnet at 9x the base rate when usage-based billing takes effect June 1, 2026. Opus models removed from Pro plans entirely (Pro+ only). Annual subscribers face the new multipliers immediately at switchover. The shift from flat monthly fees to token-based consumption fundamentally changes the economics of AI-assisted development.
