Cisco’s Antares SLMs target vulnerability localization with 350M, 1B, and 3B models
A repost highlights Antares, a family of small language models from Cisco built to help locate security vulnerabilities in codebases.
- The models come in 350M, 1B, and 3B parameter sizes.
- The workflow is framed as iterative repository navigation: read the vulnerability description, search for relevant code patterns, inspect candidate files, then update direction as new evidence appears.
- The post argues that small open models can do vulnerability detection/localization well, pushing back on the idea that only large closed models are capable of the task.
- The chart in the image compares Antares against other open and closed models on a file F1 metric, showing the Antares family near the top for its size class.
