Superagent formally launches Security-One 27B with Apache 2.0 weights and an API for probability-based security triage

What changed

Superagent formally announced Security-One 27B on October 4 as a decision model for continuous security triage. It returns probabilities for predefined options when evaluating prompts, agent tool calls, code changes or alerts so applications can apply thresholds and route suspicious cases to stronger models or people. Superagent provides both an API and Apache 2.0 weights. In the vendor's frozen binary BIPIA test at a 0.70 threshold, it reports detecting 599 of 600 attacks with one false positive among 200 benign examples; these are vendor-run results rather than a general security leaderboard. The model card lists a September 25 release date for the underlying model, so this entry records the October 4 formal public launch/API and open-weights announcement rather than claiming the checkpoint was first created that day.
