MAI-Cyber-1-Flash
Microsoft · Released Jul 2026
Microsoft's first in-house cybersecurity model, built on the MAI-Thinking-1 family and embedded inside the MDASH multi-agent harness. MAI-Cyber-1-Flash handles ~90% of security workloads at roughly half the cost of prior configurations, reserving GPT-5.4 for the hardest 10%. It scores 95.95% on CyberGym — 12 points above Mythos 5 — but this is a vendor-reported benchmark from a tuned full-system configuration (harness + dual models), not an independent model-versus-model test. Available only through Azure AI Foundry with vetted enterprise access; no standalone pricing or public API.
Is it right for you?
Good for
- Top CyberGym score (95.95%), beating Mythos 5 by 12 points and GPT-5.5-Cyber by 10 points
- Cost efficiency at scale — specialized small model handles 90% of tasks, reserving frontier models for hard 10%
- Deep integration with Microsoft's security estate — trained on decades of enterprise defense telemetry
Not good for
- Not independently benchmarked — all CyberGym scores are vendor-reported from a full-system configuration, not a controlled model comparison
- Restricted access — no public API or self-serve tier; gated behind Azure AI Foundry vetting
- Dual-use risk — built to find hard vulnerabilities, the same capability serves attackers with no built-in gating beyond access controls
How it performs by task
Vulnerability discovery
SOTA on CyberGym — finds CVEs in complex codebases that general-purpose models miss
Code patching and remediation
Generates working patches and validates them — green-team loop closes the fix cycle
General coding
Purpose-built for security; underperforms general-purpose models on non-security coding tasks
Reasoning
Competent within security domain but defers 10% of hardest queries to GPT-5.4
