This is really cool research by one of my new teammates: examining the internal state of an #LLM can not only tell you what type of information it's processing, but is really good at detecting malicious or unsafe prompt injections.

It's like fMRI for LLMs.

I read the bill's text. It doesn't actually stop sharks from eating fish. Instead, sharks must yell "You been SHARKED!" before eating, hoping to embarrass them into changing behavior.
