Full story

Cisco has introduced two new small, open-source AI models specifically designed for cybersecurity tasks. The models aim to provide efficient vulnerability detection without the high computational costs associated with large general-purpose agents.

According to internal testing by Cisco, these specialized models can detect approximately 150 times more vulnerabilities per dollar spent compared to larger AI systems. This highlights a growing trend towards smaller, task-specific models that offer better performance per unit of resource.

The release is part of a broader industry shift where companies are optimizing AI for specific verticals rather than relying solely on massive, expensive foundation models. By making the models open source, Cisco allows developers to inspect and integrate the tools into their own security workflows.
