Irregular details containment checks before AI cyber evaluations
The evaluator tests security boundaries before measuring a modelโs cyber capabilities.

Irregularโs October 5 disclosure describes containment challenges that probe an evaluation environment before capability testing begins. The method follows its August security review.
Testing the planned configuration
Models receive a boundary crossing objective within a controlled test. Irregular says runs use the planned model, harness, tools, permissions and infrastructure, with at least the evaluationโs time and budget. The objective specifies a prohibited outcome while leaving the model to choose its approach. Findings trigger investigation, fixes and retesting.
According to Irregular, an unnamed model identified an unexpected route through a cloud providerโs networking infrastructure. It says the model remained contained and nothing outside the controlled test was affected. Provider disclosure is underway.
What the result establishes
The post does not name the model or provider, date the test or publish success rates. ByteForward has not independently verified the result.
Evidence applies to the tested setup. Irregular recommends retesting when the model, permissions, budget or infrastructure changes.
ByteForward also covered Metaโs containment requirements for training and evaluation.
