AI Safety Levels (ASL)
AI Safety Levels are the tiers of safeguards in Anthropic's Responsible Scaling Policy, where each higher level requires stronger deployment and security protections once a model reaches certain capability thresholds.
In depth
AI Safety Levels are the tiers of safeguards in Anthropic's Responsible Scaling Policy, where each higher level requires stronger deployment and security protections once a model reaches certain capability thresholds. At ASL-2, models are trained to refuse dangerous CBRN requests and weights are defended against opportunistic theft. ASL-3 adds targeted protections against CBRN misuse, including defenses against universal jailbreaks, plus security built to stop sophisticated non-state attackers. Anthropic first turned on ASL-3 protections on May 22, 2025, when it launched Claude Opus 4.
