ANTARES: A SECURITY ANALYST THAT NEVER LEAVES YOUR LAPTOP – SECURITY LOOP SERIES, PART 1

Summary from the TLDR InfoSec newsletter

Antares-1B is a Cisco model, post-trained from IBM Granite 4.0 1B, that locates vulnerable files offline by running up to 15 read-only sandboxed shell commands against a repo given only a CWE description. Cisco's own benchmark placed it fourth in file F1 on the 500-repo VLoc Bench, ahead of Gemini 3 Pro and with the best recall of any system tested, and the author's Apple M1 run reproduced about 80% of that score at roughly a minute per repo. Results export as SARIF 2.1.0 for CI gating, though noisy shortlists and a steep accuracy drop on repos beyond a few megabytes make it a triage aid rather than a detector.
