Microsoft announced MAI-Cyber-1-Flash inside MDASH, its multi-agent vulnerability identification and remediation harness, saying the combined system delivers world-class performance at 50% of the cost of leading models.

The company said MAI-Cyber-1-Flash was built to find challenging vulnerabilities in complex codebases and has been deeply integrated into MDASH. Microsoft said the unified system delivers 96% on CyberGym, a benchmark for evaluating how systems reason over large codebases to find real vulnerabilities, which is 12 percentage points above Mythos. The system was designed to efficiently handle up to 90% of all tasks, enabling MDASH to use larger models such as GPT-5.4 for the 10% of exceptionally hard tasks.

Microsoft also launched Perception, an agentic security system that provides teams of agents for a variety of security workflows in MDASH to continuously monitor, patch, and close new threat vectors. The company said Perception will soon use MAI-Cyber-1-Flash for many more security workflows beyond software vulnerability work. Microsoft said the model was developed with a security-first calibration, rigorously evaluated by Microsoft's AI Red Team, and independently assessed by a third party.
