The resource_exhausted error usually means the model you’re requesting hit a load limit at that moment. It’s a temporary server-side issue, not an account or billing problem.
A couple things to try:
If you’re using Auto mode, try manually picking a specific model, like composer-1.5 or gpt-5-mini. Auto sometimes routes requests to a model that’s already overloaded. A few users confirmed this helps: Repeated High Load Error
Can you also tell me what Cursor version you’re on? That’ll help narrow it down if the workaround doesn’t help.
