Microsoft released MAI-Cyber-1-Flash, a 5B-active-parameter AI model designed for cybersecurity vulnerability detection that runs within MDASH, Microsoft's multi-model scanning system. The model achieved 95.95% on CyberGym, a benchmark of 1,507 real-world vulnerability tasks, up from 88.45% when MDASH used only general-purpose models. MDASH now routes 90% of tasks to MAI-Cyber-1-Flash while escalating the hardest 10% to GPT-5.4, reducing costs by 50% while improving vulnerability discovery performance.
