- Scalable oversight. How to evaluate systems that are much smarter than you? What to do when human raters cannot understand the consequences of an AI’s proposed actions?
- e.g. debate, amplification, ELK (?)
- Robustness. How to make sure the system will behave the way it did in training? How robust is it to changes of distribution?
- a grab bag of different techniques developed by academics, none of which works super great
- reasoned but hard in practice: try to make the AI believe it’s being deployed
- Interpretability. What is the AI thinking internally? Can you learn about the AI not just from its input-output behavior, but also from looking into its computations?
- Generalization. How do systems generalize from easy cases (on which we can supervise the model) to hard cases? What are the training conditions that make the generalization go well?
People working on it (off the top of Christiano’s head in April 2023):

- Interpretability. LLM’s are black-boxes, but this doesn’t have to be the case. Akin to “digital neuroscience”, researchers have been able to understand the purpose of different neurons within LLM’s and even reverse engineer entire circuits.
- Relevant people: Neel Nanda, Chris Olah.
- Robustness. ML models work well in their training environment, but often fail catastrophically when encountering something novel (e.g. a jailbreaker or adversary). Robustness is about finding ways to robustly (or resiliently) perform as intended.
- Relevant people: Dan Hendrycks.
- Reward specification. Part of the problem is getting something as abstract as “human values” into a computer. Techniques for doing this include RLHF/reward modelling and inverse reinforcement learning (mapping actions to intended goals).
- Relevant people: Stuart Russell.
- Truthfulness. If we can restrict AI’s to always tell the truth, it’ll be much harder to lose control of them (because if they’re planning something naughty, we can just ask them about it). Lots of work has thus gone into preventing/catching LLM deception.
- Relevant people: Evan Hubinger.
- Evals. If we want to ensure safety of advanced AI, it’s pretty important to test extremely thoroughly before deployment. This should include lots of un-intuitive and clever evals which can also help to predict dangerous capabilities in advance.
- Relevant people: Paul Christiano.
- Scalable oversight. As systems become smarter than humans, how do we keep them in check? This sort of work falls under “scalable oversight”. Proposals include recursively decomposing tasks in a way humans can verify or having AI’s debate.
- Relevant people: Paul Christiano.
- Agent foundations. Some ppl think we’re fundamentally confused on questions of agency and its application to advanced AI. Work in this area tries to find better theoretical frameworks that can help clarify our thinking on alignment.
- Relevant people: John Wentworth.
- Cyborgism/AI-assisted alignment. What if we could leverage the intelligence of AI to help us make future AI’s safer and accelerate research in other agendas? We should expect AI to only get smarter over time, so this is a winning strategy right?
- Relevant people: OpenAI, janus.
To the best of my knowledge, there are five key strategies for combating deceptive alignment (when an AI system performs well under our evaluations but still fails in deployment).
(1) Rigorous evals (incl. honeypots)
(2) Mechanistic interpretability
(3) Mechanistic anomaly detection
(4) Mechanistic adversarial examples
(5) Distillation/compression
Am I missing anything?
People in the AI safety space work a lot on 1 and 2 and somewhat on 3. But 4 and 5 seem much less a focus right now. Why is this the case?
