Mini toolsAntares 1B
Antares 1B is part of Cisco's Antares family of small language models built for vulnerability localization, connecting external vulnerability knowledge such as CWE categories and security advisories to specific files within a codebase. Built on a Granite architecture, it performs an iterative, agentic search: starting from a vulnerability description, it explores unfamiliar repositories, inspects candidate files, incorporates new evidence, backtracks when a path is unproductive, and returns a ranked list of likely vulnerable files with its exploration trace. Benchmark testing shows it outperforms many larger closed and open weight models on vulnerability localization at a fraction of the cost, while remaining compact enough to run locally.
Overview
Antares 1B is a compact security-focused language model from Cisco for locating vulnerable source files within a codebase. Given a CWE category or advisory description, it performs an agentic search through a repository, inspects candidate files, and narrows down to the files most likely to contain the flaw, running efficiently enough for local or on-premises security workflows.
