This model efficiently handles 90% of incoming attacks, allowing larger and more costly models to be used only for the 10% that truly need them. ## Cost Savings and Performance MAI-Cyber-1-Flash, combined with MDASH, offers up to 50% cost savings. This combination delivers a 96% performance on CyberGym, making it a more effective solution than the current best offering. ## Security Workflows with Perception Microsoft also launches Perception, a new agentic security system. This system provides teams for various security workflows within MDASH, continuously monitoring, patching, and closing new threat vectors. ## Model, Data, and Harness Optimization Microsoft jointly optimizes its world-class models, unique historical data, and expert-tuned harness to offer customers a powerful security solution. These three elements form the foundation of MAI-Cyber-1-Flash. ## Security-First Design As Microsoft's first cyber model, MAI-Cyber-1-Flash aims to build trust at every layer, from model training to customer deployment. The model was developed with a security-first calibration and rigorously evaluated by Microsoft's AI Red Team. ## Continuous Learning and Improvement Cybersecurity is not just a data-rich domain but also a live reinforcement learning loop. Microsoft sees this loop end-to-end, continuously improving its cyber models and turning them into expert cyber defenders. ## Sources covering this story - https://microsoft.ai/news/introducing-mai-cyber-1-flash-inside-mdash/ — --- _Summary written by Brifing from the original reporting.
