Microsoft Claims MDASH Outperforms Competitors in Cybersecurity Benchmark
Microsoft announces that its new cybersecurity model, MDASH, scores 95.95% on the CyberGym benchmark, surpassing competitors like GPT-5.6 Sol and Anthropic's Mythos. The report from Decrypt highlights MDASH's cost efficiency and advanced capabilities in vulnerability detection.
On July 27, 2026, Microsoft unveiled its latest cybersecurity model, MDASH, which reportedly achieved a score of 95.95% on the CyberGym benchmark. This score places it ahead of several other prominent models, including GPT-5.5 Cyber at 85.6%, Mythos 5 at 83.8%, and GPT-5.6 Sol at 83.6%. CyberGym tests AI agents by having them reproduce 1,507 known vulnerabilities spread across 188 open-source projects.
According to Microsoft, the new model demonstrates significant cost efficiency, operating at half the cost of its previous best configuration. This efficiency is particularly notable as MDASH, when combined with MAI-Cyber-1-Flash, is said to handle up to 90% of tasks, while routing the most challenging cases to the older GPT-5.4 model. This combination is designed to reduce costs as tokens, which represent the text data processed by AI, incur expenses each time a model is engaged.
“When combined with MDASH, (MAI-Cyber-1-Flash) delivers world-class performance at 50 percent of the cost of leading models,” stated Microsoft CEO Satya Nadella. He emphasized that this model represents a significant advancement in efficient cybersecurity solutions.
While these results show promise, it is important to note that the scores indicated are self-reported by Microsoft and have not yet been verified in CyberGym's public results. As Microsoft continues to roll out its cybersecurity capabilities, it will be critical to monitor independent assessments and industry reactions to MDASH's performance and its impact on the cybersecurity landscape.
