More details on Fable 5’s cyber safeguards and our jailbreak framework

Anthropic News ● Covered by 5 sources

Anthropic deployed Claude Fable 5 with new safety classifiers designed to detect and block dangerous cybersecurity uses, while releasing a framework to categorize jailbreak severity. The classifiers sort cybersecurity requests into four categories: prohibited use (ransomware, malware development, data exfiltration), high-risk dual use (penetration testing, exploit development), low-risk dual use (vulnerability identification that other models can already do), and benign use (secure coding, debugging). The framework aims to establish consistent terminology for discussing AI jailbreak risks across government, industry, and academia, with feedback welcomed at cyber-safeguards@anthropic.com and a HackerOne bug bounty program now active.
