Used Anthropic API with Sonnet 4 MAX before hitting the monthly PRO quota (500 requests). Constantly and annoyingly running into Rate exhaustion erros after just a few chained tool calls. Fine, swtiched back to inbuilt request mode until I hit the 500. Back into API mode and after a few minutes Sonnet 4 disappeared from the model selection. Disabling API and restarting Cursor : voila , Sonnet 4 is back. Switching back to API mode again, and Sonnet 4 is gone again. WTF is going on here?
Hey, that’s quite strange. I just checked and I have this model with the API key enabled. Try adding this model manually with the API key enabled.
Thanks Dean. When adding manually, MAX mode was not available. I just restarted my machine ( Win 10 ) and the manually added is now supporting MAX. I will test some more scenarios.
