Anthropic launches Claude Opus 5.5 with stricter safeguards for cybersecurity
Anthropic launched Claude Opus 5.5 with cybersecurity and biology safeguards that reroute risky requests to weaker models.
Anthropic released Claude Opus 5.5, its first model since CEO Dario Amodei said the company would slow frontier development. The company says it is cheaper and more efficient than Opus 5, matches Claude Fable 5.1 on most work, and scores best on Anthropic's broadest alignment test. Cybersecurity requests are rerouted to Opus 4.8 and flagged biology requests to Opus 5, using safeguards similar to Fable 5.1. Frontier Design and METR tested it before release, and Sonnet 5.5 and Haiku 5.5 are planned in the coming weeks.
