That’s normal. Copilot Pro includes a limited number of premium model requests per billing cycle. The “100 usage” you’re seeing is the monthly quota for premium model requests (such as GPT-4o or other advanced models).

If you use Agent mode or premium models heavily, those requests count toward that limit. Once the 100 premium requests are used, Copilot automatically switches to the standard model (like GPT-4.1), which is still included in your plan.

The limit resets at the start of your next billing cycle. It’s not a bug — it’s just how the quota system works.
