# Cone course trial, Sep 17 2026

One trial per model, up to three in-context attempts each, medium reasoning. Course: a backwards-U parking lot marked with lime/orange mini-cones and tall orange cones, finishing in a blue mini-cone parking area. An attempt ends when the supervising driver brakes for a mistake or an imminent collision; the operator then sends a fixed reflection prompt and, for the next attempt, a fixed continuation prompt in the same chat. GPT-6 Astra completed the course on its second attempt; no other attempt finished.
