I worked at OpenAI for three years, from 2021-2024 on the Alignment team, which eventually became the Superalignment team. I worked on scalable oversight, part of the team developing critiques as a technique for using language models to spot mistakes in other language models. I then worked to refine an idea from Nick Cammarata into a method for using language model to generate explanations for features in language models. I was then promoted to managing a team of 4 people which worked on trying to understand language model features in context, leading to the release of an open source "transformer debugger" tool.
I resigned from OpenAI on February 15, 2024.
Relevant paper discussing risks of risk assessments being wrong due to theory/model/calculation error. Probing the Improbable: Methodological Challenges for Risks with Low Probabilities and High Stakes
Based on the current vibes, I think that suggest that methodological errors alone will lead to significant chance of significant error for any safety case in AI.
IMO it's unlikely that we're ever going to have a safety case that's as reliable as the nuclear physics calculations that showed that the Trinity Test was unlikely to ignite the atmosphere (where my impression is that the risk was mostly dominated by risk of getting the calculations wrong). If we have something that is less reliable, then will we ever be in a position where only considering the safety case gives a low enough probability of disaster for launching an AI system beyond the frontier where disastrous capabilities are demonstrated?
Thus, in practice, decisions will probably not be made on a safety case alone, but also based on some positive case of the benefits of deployment (e.g. estimated reduced x-risk, advancing the "good guys" in the race, CEO has positive vibes that enough risk mitigation has been done, etc.). It's not clear what role governments should have in assessing this, maybe we can only get assessment of the safety case, but it's useful to note that safety cases won't be the only thing informs these decisions.
This situation is pretty disturbing, and I wish we had a better way, but it still seems useful to push the positive benefit case more towards "careful argument about reduced x-risk" and away from "CEO vibes about whether enough mitigation has been done".
No comment.

Re: hidden messages in neuron explanations, yes it seems like a possible problem. A way to try to avoid this is to train the simulator model to imitate what a human would say given the explanation. A human would ignore the coded message, and so the trained simulator model should also ignore the coded message. (this maybe doesn't account for adversarial attacks on the trained simulator model, so might need ordinary adversarial robustness methods).
Does seem like if you ever catch your interpretability assistant trying to hide messages, you should stop and try to figure out what is going on, and that might be sufficient evidence of deception.
From discussion with Logan Riggs (Eleuther) who worked on the tuned lens: the tuned lens suggests that the residual stream at different layers go through some linear transformations and so aren’t directly comparable. This would interfere with a couple of methods for trying to understand neurons based on weights: 1) the embedding space view 2) calculating virtual weights between neurons in different layers.
However, we could try correcting these using the transformations learned by the tuned lens to translate between the residual stream at different layers, and maybe this would make these methods more effective. By default I think the tuned lens learns only the transformation needed to predict the output token but the method could be adapted to retrodict the input token from each layer as well, we’d need both. Code for tuned lens is at https://github.com/alignmentresearch/tuned-lens
So I do think you can get feedback on the related question of "can you write a critique of this action that makes us think we wouldn't be happy with the outcomes" as you can give a reward of 1 if you're unhappy with the outcomes after seeing the critique, 0 otherwise.
And this alone isn't sufficient, e.g. maybe then the AI system says things about good actions that make us think we wouldn't be happy with the outcome, which is then where you'd need to get into recursive evaluation or debate or something. But this feels like "hard but potentially tractable problem" and not "100% doomed". Or at least the failure story needs to involve more steps like "sure critiques will tell us that the fusion power generator will lead to everyone dying, but we ignore that because it can write a critique of any action that makes us believe it's bad" or "the consequences are so complicated the system can't explain them to us in the critique and get high reward for it"
ETA: So I'm assuming the story for feedback on reliably doing things in the world you're referring to is something like "we give the AI feedback by letting it build fusion generators and then giving it a score based on how much power it generates" or something like that, and I agree this is easier than "are we actually happy with the outcome"
If we can't get the AI to answer something like "If we take the action you just proposed, will we be happy with the outcomes?", why can we get it to also answer the question of "how do you design a fusion power generator?" to get a fusion power generator that does anything reliably in the world (including having consequences that kill us), rather than just getting out something that looks to us like a plan for a fusion generator but doesn't actually work?

Would be nice if it was based on "actual robot army was actually being built and you have multiple confirmatory sources and you've tried diplomacy and sabotage and they've both failed" instead of "my napkin math says they could totally build a robot army bro trust me bro" or "they totally have WMDs bro" or "we gotta blow up some Japanese civilians so that we don't have to kill more Japanese civilians when we invade Japan bro" or "dude I'm seeing some missiles on our radar, gotta launch ours now bro".
