Cursor: We're experiencing high demand for Claude 4 Sonnet right now
Cursor error message: We’re experiencing high demand for Claude 4 Sonnet right now. Please switch to the ‘auto-select’ model, another model, or try again in a few moments.

Recently, after Cursor started supporting Claude 4 Sonnet, many users of the student version and the 14-day trial have reported frequently encountering the issue mentioned above.
However, none of the officially subscribed Cursor Pro users I know have encountered this problem. So I guess Cursor is currently prioritizing access to Claude 4 Sonnet for officially subscribed users and only making it available to student version and 14-day trial users during off-peak times (this is my speculation and might not be accurate).
