Claude Mythos, Anthropic's cybersecurity-focused AI model, is now available as a gated research preview on Amazon Bedrock via Project Glasswing, targeting security teams for vulnerability discovery. AWS Agent Registry launched in preview through Amazon Bedrock AgentCore, offering a private catalog for discovering and managing AI agents, tools, and MCP servers. Other highlights include Amazon S3 Files (S3 buckets as shared file systems), Amazon OpenSearch Service adding Managed Prometheus and AI agent tracing, Amazon WorkSpaces Advisor for AI-powered IT troubleshooting, and Amazon Braket gaining access to Rigetti's 108-qubit Cepheus QPU. Amazon Bedrock also added cost allocation by IAM user and role for better AI spending visibility. ## Full article daily.dev links to this article rather than hosting it.
