Support Claude 4 with AWS Bedrock

Bug Reports
1

Seemingly I always encounter this error message while trying to use the Claude 4 (Sonnet/Opus) model ID with AWS Bedrock API Key. Claude 3.7 is working but 4 just never works. Does this mean Cursor haven’t supported that?

And I am also wondering why we cannot use the common Claude model name when using AWS api key. It seems models from AWS are treated differently compared with the default Claude model?

Seconding this request. Strangely I am getting rate limited hard on 3.7 with bedrock, but can’t even send a single request to claude 4. Also can’t use thinking modes when using bedrock.
