Span-01
By Respan · Released 24 Sep 2026
A one-pass classifier for agent traces. For each behaviour you define, it returns the probability that it is present, absent or not observable, without generating text. Its successor, Span-02 (15 Oct 2026), reads images too, can return a number directly, and ships as Apache-2.0 open weights.
