Rather than detecting specific CVEs or generating patches, Antares acts as a search assistant that ranks source files by relevance, reducing investigation fatigue. The 3B model reportedly approaches GPT-5.5 performance on Cisco's internal vulnerability localization benchmark while being small enough for single-GPU local deployment. Models are available on Hugging Face and support SARIF output, CLI-based CWE scans, and local inference to keep proprietary code within organizational trust boundaries. Cisco positions Antares as complementary to — not a replacement for — existing tools like Semgrep or CodeQL and human security analysts. ## Full article daily.dev links to this article rather than hosting it.
