The model multiplier changes outlined in this article apply only to Copilot Pro and Copilot Pro+ subscribers who stay on their existing annual plan after June 1, 2026 and remain on the premium request-based billing model.
If you choose to switch to monthly usage-based billing (with a prorated refund), these multiplier changes do not apply to you.
What is changing with Copilot billing?
GitHub is changing how Copilot usage is measured and billed.
Today, each model interaction costs one premium request unit (PRU), and a multiplier is applied based on which model you use—more powerful models use more premium requests. Model multipliers are a concept specific to the current request-based billing system.
Starting June 1, 2026, GitHub is replacing 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 will come with an included allowance of GitHub AI Credits, with the option to set a budget for additional usage.
Model multipliers do not apply to usage-based billing.
What are my options as a Copilot Pro and Copilot Pro+ user on an existing annual plan?
If you're on an existing annual plan for Copilot Pro or Copilot Pro+, you will have the option to:
- Stay on your existing annual plan under premium request-based billing. When your annual plan ends, you'll be automatically downgraded to Copilot Gratuito.
- Cancel your plan, receive a prorated refund, and optionally, re-subscribe to the equivalent monthly paid plan.
- 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.
What happens if I keep my annual plan?
Your existing annual plan will continue to track your Copilot expenditure using premium requests, combined with the model multiplier, until the plan ends.
In addition, if you keep your annual plan under request-based billing, you will experience changes to model multipliers starting June 1, 2026. The table below shows how the multipliers for each model will adjust.
Model multipliers for annual Copilot Pro and Copilot Pro+ subscribers
The table below shows how the multipliers for each model will change on June 1, 2026.
These new multipliers will only apply if you remain on an annual Copilot Pro and Copilot Pro+ under the premium request-based billing model after June 1, 2026.
