> Anthropic says Claude Opus 5.5 introduces stronger safeguards after recent rogue AI hacking incidents, including improvements against attempts to escape testing environments. The company calls it its strongest-performing model on its broadest alignment test; it costs 40% less to run than Opus 5 and routes some cybersecurity requests to the less powerful Opus 4.8.
