Cisco's small AI models outperform GPT-5.5 on cybersecurity vulnerability detection

By PulseAugur Editorial · [2 sources] ·

Cisco has launched two new open-source AI models specifically designed for cybersecurity. The company claims these smaller models can identify approximately 150 times more vulnerabilities per dollar compared to larger AI models like GPT-5.5. This approach emphasizes efficiency over scale, suggesting a potentially more cost-effective strategy for security vulnerability detection. AI

IMPACT Suggests a more cost-effective approach to AI-driven cybersecurity, potentially challenging the dominance of larger, more general-purpose models.
