Does this stop you from using Cursor

No - Cursor works, but with this issue

hello @condor ,

any update on this problem? I’m getting the same issue but I can’t use Cursor with Bedrock with it, I keep getting “the model does not work with your current plan or api key” although I do have all the permissions to use the model that I want (including Bedrock model access, IAM User with the correct permissions, etc..)

Hey, most likely your API key didn’t pass verification and you’re trying to use a model in Cursor that isn’t included in your subscription, which is why you’re getting this error. Make sure you have a valid API key, try regenerating your key, and enable it again.
