Claude Fable 5 on Bedrock Requires Sharing Inference Data with Anthropic

Users deploying Anthropic's Claude 3.5 Sonnet or Haiku models on Amazon Bedrock must now opt into data sharing, which sends prompts and outputs to Anthropic for 30-day retention and human review. This update marks a shift from previous Bedrock standards, which kept inference data contained within the AWS environment. The policy change impacts organizations with strict data privacy requirements that previously relied on Bedrock’s isolated infrastructure for model interactions.
