- Microsoft launched MAI-Cyber-1-Flash, its first cybersecurity-specialized AI model, at a San Francisco event on Monday.
- MAI-Cyber-1-Flash, paired with OpenAI's GPT-5.4 inside Microsoft's MDASH harness, scored 96% on the CyberGym benchmark — 12 percentage points above Anthropic's Mythos.
- The Microsoft model runs at 50% of the cost of Microsoft's existing MDASH configuration.
- Microsoft also debuted Project Perception, a new agentic security platform, alongside the model launch.
Why it matters: Microsoft beat Anthropic's Mythos by 12 points on the CyberGym benchmark while halving the cost of its own current MDASH setup — a direct price-performance challenge to Anthropic, which has been a leading name on cybersecurity AI benchmarks.
