Ask HN: How are current LLMs designed around safety, practically?

Just watched a Lex Fridman/Zuckerberg podcast clip[0] about facebook's new LLaMA model. I am so utterly unconvinced that Facebook of all companies are only holding their LLM progress back because of safety/alignment concerns. I see the entire company-led "safety discussion" around AI at the moment as nothing more than OpenAI wanting to reduce competition and the rest to afford themselves enough time to catch up. My impression is that we're in the middle of a gold rush, and if companies are sitting on technology which could dethrone OpenAI they would do it in a heartbeat.

How are LLM's, right now in 2023, being designed and modified to actually be safer in a concrete way?
