Opus 5 ships with extended thinking enabled by default and inherits the cybersecurity vulnerability-finding prowess of its predecessor, all without explicit exploitation training. The price-performance ratio matters because it enables longer autonomous agent execution, though it introduces new operational headaches: teams now need microVMs, semantic circuit breakers, and tighter telemetry to safely deploy unsupervised AI agents that run unattended for hours.
