Cisco Releases Antares: Open-Weight Models for Vulnerability Localization
Cisco released Antares-350M and Antares-1B, two open-weight small language models that locate where known vulnerabilities live inside a codebase. Both are free on Hugging Face and can run locally, allowing organizations to keep proprietary code inside their own environment. Antares finds candidate files. It does not generate fixes. A larger version, Antares-3B, is coming later.
