Machine Learning Blog



This article discusses AWS's approach to safely releasing frontier AI models, specifically Anthropic's Claude Fable 5, on Amazon Bedrock with enhanced security guardrails.

  • Claude Fable 5 models now available on Bedrock with stronger guardrails to prevent adversary misuse
  • Balances giving defenders advanced cybersecurity capabilities while protecting against adversary access to vulnerability research
  • AWS Red Team collaborated with Anthropic to improve model protections and minimize misuse risk
  • Falls back to Opus 4.8 when guardrails are triggered, maintaining capability while ensuring safety
  • Anthropic published severity levels and SLAs for responding to reported issues with cyber-capable models
  • Industry partnership through Project Glasswing to refine guardrails for this new class of models

AWS emphasizes the importance of making advanced AI capabilities securely available to all customers while maintaining responsible safeguards against misuse.
