Anthropic's models are currently at AI Safety Level ASL-2.

True: as of 2024-04-12, Anthropic's official materials (Responsible Scaling Policy, model cards, system cards for Claude 3 models) show its deployed models were assessed at, and covered by, ASL-2 standards. Mostly true: models were under ASL-2 with a minor caveat (for example some precautionary ASL-3 preparation under way) that does not change the classification. Mixed: not used for this single-fact claim. Mostly false: Anthropic's records show the classification at that date was ambiguous or that some current models were already treated under ASL-3. False: Anthropic records show its models were at ASL-3 or higher (or ASL-1) as of that date.

   “Classified ASL-2 in the Claude 3 model card after Anthropic's evaluations showed no indicators of catastrophic risk.”

Anthropic's Responsible Scaling Policy announcement (E1) says that current LLMs, including Claude, appear to be ASL-2. An independent reference (E2) reports that the Claude 3 model card classified those models as ASL-2 because Anthropic's evaluations showed no signs of catastrophic risk. Neither source shows any deployed model being treated under ASL-3 at the time. Together they indicate that Anthropic's models were classified as ASL-2 around April 2024, although E1 says only that they 'appear to be' ASL-2 and E2 is a secondary summary of the Claude 3 model card.
