tl;dr: Microsoft launched MAI-Cyber-1-Flash, a compact security-focused model integrated into its MDASH vulnerability remediation harness, designed to handle ~90% of security tasks while reserving larger models like GPT-5.4 for harder cases. The combined system scores 96% on CyberGym while cutting costs 50% versus their previous best MDASH configuration. Microsoft also introduced Perception, an agentic security system providing agent teams for continuous monitoring, patching, and threat response workflows.
