> To be clear, we have not yet determined whether Claude Opus 4 has definitively passed the Capabilities Threshold that requires ASL-3 protections. Rather, due to continued improvements in CBRN-related knowledge and capabilities, we have determined that clearly ruling out ASL-3 risks is not possible for Claude Opus 4 in the way it was for every previous model, and more detailed study is required to conclusively assess the model’s level of risk. (We have ruled out that Claude Opus 4 needs the ASL-4 Standard, as required by our RSP, and, similarly, we have ruled out that Claude Sonnet 4 needs the ASL-3 Standard.)

"Safety Levels" will continue to increase until state power is deployed to suppress competition.

They claim that their new LLM, unfettered, is so good that they are concerned that it might be able to provide instructions to make things like nuclear weapons. A mediocre physicist could provide similar, or better, instructions, but nobody is trying to shut down physics departments at universities.

This is a sales pitch wrapped in over-compliance and presented as an alert. This is pathetic, but I am somewhat entertained by their desperation; I will be even more entertained when LLM companies start using sex-appeal to sell subscriptions ("women find our latest model weights to be irresistible, so sign up now for our $1000/month plan").
