Cisco announced the Antares family in Dubai on July 28 — two compact models, Antares-350M and Antares-1B, released openly to developers and the security community for software vulnerability detection. The pitch is explicitly about keeping source code inside your own environment: small enough to run locally, so teams without budget for frontier-model security tooling can scan without shipping code to a third party. This is the small-model counterpoint to Microsoft's frontier-scale MAI-Cyber-1-Flash announcement the same week, though the claim is single-sourced so far with no published benchmark comparison against larger cyber models.
