Microsoft says that when integrated with OpenAI's GPT-5.4, its new cybersecurity model can beat Anthropic's new Mythos 5.

Microsoft says its new cyber model lets more than 100 AI agents find software flaws at half the cost of its current best MDASH configuration.

Microsoft has announced two major cybersecurity advancements: its first in-house security AI model, MAI-Cyber-1-Flash, and Project Perception, an agentic AI security system.
