Benchmarked on 900 unseen tickets

Independent OOD bench (source): 300 queue-routing choices, 300 mood booleans, 300 priority scores. Reflex-1 ran the full suite in September 2026, one judgment per question. Bars show accuracy; ECE figures are listed below.

SemIf-authored144: Reflex-1 65.3% accuracy (94/144 valid responses) — chance is 33.3%. OOD runs: single-judgment inference, temp 0. Reflex-1 learned related ticket templates, so treat the gap as improvement on this task family, not proof on unseen domains.
