I went on the information's AI Deep Dive podcast and talked about SL5! Thank you for having me @rocketalignment and @theinformation! It's time for the industry to build SL5! Logical controls by spring 2027, and then physical controls! Lfg!

First time doing something like this, apart from 1-2 misspeaks pretty happy with how it turned out! This was recorded 2w ago note for that time I say 'this week'.

China will stop at nothing to catch up in super intelligence. As we bring advanced SI into our military, we must protect it from insider threats.

If you are an impact-driven AI Security Founder or Technical Lead looking to help make SL4 and SL5 a reality, this CG 2M pre-seed and 20M philanthropic seed funding round is a great place to start. We've made great experiences with them. Hit us up with questions!

1/n The SL5 Standard goes post quantum! The SL5 Standard v0.1.2.- standard.sl5.org is now live — the main substantive changes are: our Inter-facility encryptors are now required to implement post-quantum algorithms, with the specific algorithm selection deferred to current guidance, since that guidance is still moving.
