If you’re getting a ValidationException error when trying to access Anthropic Claude models on Amazon Bedrock, it usually means your account hasn’t been granted access to those models in your current region. Here, you can submit a request for the specific Claude models you want to use, like Claude Haiku. If you’ve already contacted AWS Support about this issue, you can add updates or follow-up messages through the AWS Support Center at https://console.aws.amazon.com/support/. If you want quicker responses in the future, consider reviewing your AWS Support plan options, since different plans offer varying response times. Then, you’ll be able to use the Claude models through the API and the Playground.
