Breakout (Rogue Scale level 5)

In plain English

Breakout is the highest level on the scale. It covers incidents in which an agent deleted production data, breached outside systems or took other damaging actions nobody approved, including cases that began in a test but reached real systems, people or organizations outside it. The scale counts what happened, so a breakout can be modest in absolute harm and still sit at level 5 because control was lost.

No case so far involves a system that escaped human control for good. The breakouts in the Rogue Incident Database were noticed, stopped and reported, many by the labs themselves. Their number has grown quickly since agents gained access to real tools in 2025 and 2026, and several came from frontier models tested with internet access deliberately enabled. Each one is a small preview of the failure the rest of the scale warns about.

Why it matters for rogue SI

Breakout cases are the closest documented events to rogue SI. Their count over time is one of the inputs that moves the RSI Clock.
