I’m calling it. Jailbreaks will be solved in 2024. RepEng LFG.
No LLM is secure! A year ago, we unveiled the first of many automated jailbreak capable of cracking all major LLMs. 🚨 But there is hope?! We introduce Short Circuiting: the first alignment technique that is adversarially robust. 🧵 📄 Paper: arxiv.org/abs/2406.04313

If you'd asked me a year ago, superposition would have been by far the reason I was most worried that mechanistic interpretability would hit a dead end. I'm now very optimistic. I'd go as far as saying it's now primarily an engineering problem -- hard, but less fundamental risk.
The fact that most individual neurons are uninterpretable presents a serious roadblock to a mechanistic understanding of language models. We demonstrate a method for decomposing groups of neurons into interpretable features with the potential to move past that roadblock.

Centuries after probability theory was developed, many philosophers still treat belief and justification as binary rather than continuous properties. Now the theory of logical induction allows us to treat rationality as continuous too, but who knows how long until that sinks in?

You don't need to be deeply pessimistic about AI to think it's good to work on AI safety, just like you don't need to be deeply pessimistic about planes to think it's good to work on aviation safety. Risk reduction is valuable across a wide range of risk estimates.

At OpenAI a lot of our work aims to align language models like ChatGPT with human preferences. But this could become much harder once models can act coherently over long timeframes and exploit human fallibility to get more reward. 📜Paper: arxiv.org/abs/2209.00626 🧵Thread:
