Antares-1B
A 1B open-weight security-focused model that helps security engineers and dev teams locate known vulnerabilities in repositories and produce likely file/code-location leads.
Tool overview
Verdict: Antares-1B is worth a look if your goal is to quickly narrow down where known vulnerabilities may live inside a code repository. It is not a general coding copilot, not an automatic code-fix system, and not a full SAST platform. A better analogy is a specialized small model for vulnerability localization.
Based on the available evidence, its practical role is to help teams identify files or code regions more likely to contain known vulnerabilities, useful for security triage, research workflows, or as a layer alongside existing scanning pipelines. Multiple social posts describe it as Cisco’s security-focused open-weight model on Hugging Face. Some posts also cite VLoc Bench Phase A and claim Antares-1B reached 0.209 File F1 with a strong overall rank. That supports the intended capability direction, but most of it is still reposted or summarized rather than independently verified hands-on evaluation.
On cost and adoption, the evidence supports that weights are openly available and self-hosting is plausible; it does not support any stable hosted pricing, API fee, or enterprise service guarantee.
