## AI overview

The article explains how Gremlin's Experiment Analysis uses machine learning and observability context to identify why Chaos Engineering tests fail, reducing the manual effort needed to investigate system behavior. It also emphasizes defining expected behavior as the basis for pass/fail decisions, illustrated by a zone failover scenario.
