Benchmarked on unseen tickets, intents, and entailment

Independent OOD bench (source): 300 queue-routing choices, 300 mood booleans, 300 priority scores — plus SemIf-144 and Banking77-1200 (20-way intents, reserved test split). Reflex-1 ran the full suite in September 2026, one judgment per question. Jev re-measured 2026-09-24 via OpenRouter (pinned typesafe/jev-1.13-20260917). Bars show accuracy.

SemIf-144: Reflex-1 78.5% (113/144) vs Jev 97.2% (140/144) — SemIf is public and likely in Jev's training mix; chance is 33.3%. Banking77-1200 (20-way intents, chance 5%): Reflex-1 89.7% vs Jev 88.5% on the reserved test split. 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.

Reflex Pilot

A city car driven entirely by classifier calls — every steering choice streams from this API at ~300 ms. It drove a full 735 m route with zero contacts.

2048

One board, one classifier call per move. The model reached tile 64 in 74 moves with zero invalid answers. Play manually with arrows, or let it play.
