Cursor is too slow or doesn't generate responses on paid plan

It takes minutes to generate an answer sometimes. Usually about a minute to see anything. I have downgraded to 47.9, but it keeps generating the answer very slowly or hangs.

Same issue here.

Came here to report the same issue. Cursor has been basically unusable since it takes almost two minutes to do a simple model call to even something like 4o-mini. I see others are having similar issues in this thread as well: Cursor causing extreme lag

If you are waiting for tons of tool calls before seeing anything happen, just know that agent behaves much differently with Sonnet (I’m using 3.7).
Talking about agent behavior, not base model performance:
Sonnet: 0-2 min
4o-mini, o3: 2-20 min
