Model multipliers are a concept specific to this legacy request-based billing model.\n\nAs of June 1, 2026, GitHub replaced request-based billing with usage-based billing, where the cost of an interaction depends on two things: the **model** and the **number of tokens consumed**. Under usage-based billing, each plan comes with an included allowance of GitHub AI Credits, with the option to set a budget for additional usage. To learn more about usage-based billing, see [Usage-based billing for individuals](/en/copilot/concepts/billing/usage-based-billing-for-individuals).\n\n## What are my options as a Copilot Pro and Copilot Pro+ user on an existing annual plan?\n\nIf you're on an existing **annual plan** for Copilot Pro or Copilot Pro+, you have the option to:\n\n* **Stay** on your existing annual plan under premium request-based billing. When your annual plan ends, you'll be automatically downgraded to Copilot Free.\n* **Cancel** your plan, receive a prorated refund, and optionally, re-subscribe to the equivalent monthly paid plan.\n* **Upgrade** to a monthly paid plan and receive prorated credits for the remaining value of the annual plan. For example, if you're on a Copilot Pro annual plan, you can upgrade to a monthly Copilot Pro+ plan.\n\n## What happens if I keep my annual plan?\n\nYour existing annual plan will continue to track your Copilot expenditure using premium requests, combined with a model multiplier, until the plan ends. See [Model multipliers for annual plans on request-based billing (legacy)](/en/copilot/reference/copilot-billing/request-based-billing-legacy/model-multipliers-for-annual-plans).\n\n## Further reading\n\n* To understand more about how the new usage-based billing works, see [Usage-based billing for individuals](/en/copilot/concepts/billing/usage-based-billing-for-individuals).\n* To learn more about model prices under usage-based billing, see [Models and pricing for GitHub Copilot](/en/copilot/reference/copilot-billing/models-and-pricing)."}
