I’ve had a pro subscription and curing Cursor with default settings for a long time. Recently I’ve added my openai api key and switched the model to o3 to try something out. Then switched back to claude sonnet and getting an error “We encountered an issue when using your Anthropic API key. Please check your API key settings and try again.” I never had to provide any anthropic api key.

OK I’ve turned off the OpenAI API key and sonnet is working now. Is this the expecteed behavior?
Hey, you need to disable your API key every time you need a model from your subscription.
