Overview
- On Monday, July 27, Microsoft announced MAI‑Cyber‑1‑Flash and said the model running inside its MDASH harness scored roughly 96% on the CyberGym vulnerability benchmark according to company tests.
- MDASH is an orchestration system that assigns more than 100 specialized AI agents to stages such as scanning, validation, deduplication, and proof‑of‑concept generation so findings are confirmed before they reach developers.
- Microsoft reports that MAI‑Cyber‑1‑Flash handles about 90% of routine tasks and routes the hardest 10% to larger models like GPT‑5.4, which the company says cuts scanning token costs by about half compared with its prior MDASH mix.
- The MDASH configuration with MAI‑Cyber‑1‑Flash is in a limited private preview through Microsoft Defender with repository and concurrency caps, and Project Perception, the broader agentic platform, is scheduled to enter public preview on August 3.
- Microsoft says it built layered safety controls, internal red‑team testing, and a third‑party assessment into the rollout, but the firm‑reported benchmark result had not appeared on CyberGym’s public leaderboard and independent verification details remain limited.
