Microsoft Cyber Model MAI-Cyber-1-Flash Cuts Costs 50%, Handles 90% Tasks

Microsoft deploys MAI-Cyber-1-Flash for 90% of security tasks, reducing costs by half versus GPT-5.4. Public testing for Project Perception starts Aug 3.

Woofun AI reports that Microsoft has launched MAI-Cyber-1-Flash, a 137-billion-parameter cybersecurity model integrated into the MDASH vulnerability scanning system. The model handles up to 90% of discovery and remediation tasks, routing the remaining 10% to GPT-5.4, resulting in nearly 50% lower costs compared to existing GPT solutions.

In CyberGym testing, the MAI-Cyber-1-Flash and GPT-5.4 combination achieved a 95.95% score, outperforming GPT-5.5 Cyber and Anthropic Mythos 5. The model will also integrate with Project Perception, which begins public testing on August 3rd, while MAI-Cyber-1-Flash remains in private testing for audited MDASH clients.
