Oh, I do think a bunch of my problems with WebGPT is that we are training the system on direct internet access.

I agree that "train a system with internet access, but then remove it, then hope that it's safe", doesn't really make much sense. In-general, I expect bad things to happen during training, and separately, a lot of the problems that I have with training things on the internet is that it's an environment that seems like it would incentivize a lot of agency and make supervision really hard because you have a ton of permanent side effects.

Here is an example quote from the latest OpenAI blogpost on AI Alignment:

Language models are particularly well-suited for automating alignment research because they come “preloaded” with a lot of knowledge and information about human values from reading the internet. Out of the box, they aren’t independent agents and thus don’t pursue their own goals in the world. To do alignment research they don’t need unrestricted access to the internet. Yet a lot of alignment research tasks can be phrased as natural language or coding tasks.

This sounds super straightforwardly to me like the plan of "we are going to train non-agentic AIs that will help us with AI Alignment research, and will limit their ability to influence the world, by e.g. not giving them access to the internet". I don't know whether "boxing" is the exact right word here, but it's the strategy I was pointing to here.

I think the smiling example is much more analogous than you are making it out here. I think the basic argument for "this just encourages taking control of the reward" or "this just encourages deception" goes through the same way.

Like, RLHF is not some magical "we have definitely figured out whether a behavior is really good or bad" signal, it's historically been just some contractors thinking for like a minute about whether a thing is fine. I don't think there is less bayesian evidence conveyed by people smiling (like, the variance in smiling is greater than the variance in RLHF approval, and so the amount of information conveyed is actually more), so I don't buy that RLHF conveys more about human preferences in any meaningful way.

and in particular the abstraction which it seems John is using, where making progress on outer alignment makes almost no difference to inner alignment

I am confused. How does RLHF help with outer alignment? Isn't optimizing fur human approval the classical outer-alignment problem? (e.g. tiling the universe with smiling faces)

I don't think the argument for RLHF runs through outer alignment. I think it has to run through using it as a lens to study how models generalize, and eliciting misalignment (i.e. the points about empirical data that you mentioned, I just don't understand where the inner/outer alignment distinction comes from in this context)

I agree that having many shots is helpful, but lacking them is not the core difficulty (just as having many shots to launch a rocket doesn't help you very much if you have no idea how rockets work).

I do really feel like it would have been really extremely hard to build rockets if we had to get it right on the very first try.

I think for rockets the fact that it is so costly to experiment with stuff, explains the majority of the difficulty of rocket engineering. I agree you also have very little chance to build a successful space rocket without having a good understanding of newtonian mechanics and some aspects of relativity, but I don't know, if I could just launch a rocket every day without bad consequences, I am pretty sure I wouldn't really need a deep understanding of either of those, or would easily figure out the relevant bits as I kept experimenting.

The reason why rocket science relies so much on having solid theoretical models is because we have to get things right in only a few shots. I don't think you really needed any particularly good theory to build trains for example. Just a lot of attempts and tinkering.

I think the story would be way different if the actual risk posed by WebGPT was meaningful (say if it were driving >0.1% of the risk of OpenAI's activities).

Huh, I definitely expect it to drive >0.1% of OpenAI's activities. Seems like the WebGPT stuff is pretty close to commercial application, and is consuming much more than 0.1% of OpenAI's research staff, while probably substantially increasing OpenAI's ability to generally solve reinforcement learning problems. I am confused why you would estimate it at below 0.1%. 1% seems more reasonable to me as a baseline estimate, even if you don't think it's a particularly risky direction of research (given that it's consuming about 4-5% of OpenAI's research staff).

I believe the most important drivers of catastrophic misalignment risk are models that optimize in ways humans don't understand or are deceptively aligned. So the great majority of risk comes from actions that accelerate those events, and especially making models smarter. I think your threat model here is quantitatively wrong, and that it's an important disagreement.

I agree with this! But I feel like this kind of reinforcement learning on a basically unsupervisable action-space while interfacing with humans and getting direct reinforcement on approval is exactly the kind of work that will likely make AIs more strategic and smarter, create deceptive alignment, and produce models that humans don't understand.

I do indeed think the WebGPT work is relevant to both increasing capabilities and increasing likelihood of deceptive alignment (as is most reinforcement learning that directly pushes on human approval, especially in a large action space with permanent side effect).

But people attempting to box smart unaligned AIs, or believing that boxed AIs are significantly safer because they can't access the internet, seems to me like a bad situation. An AI smart enough to cause risk with internet access is very likely to be able to cause risk anyway, and at best you are creating a super unstable situation where a lab leak is catastrophic.

I do think we are likely to be in a bad spot, and talking to people at OpenAI, Deepmind and Anthropic (e.g. the places where most of the heavily-applied prosaic alignment work is happening), I do sure feel unhappy that their plan seems to be to be banking on this kind of terrifying situation, which is part of why I am so pessimistic about the likelihood of doom.

If I had a sense that these organizations are aiming for a much more comprehensive AI Alignment solution that doesn't rely on extensive boxing I would agree with you more, but I am currently pretty sure they aren't ensuring that, and by-default will hope that they can get far enough ahead with boxing-like strategies.

If you thought that researchers working on WebGPT were shortening timelines significantly more efficiently than the average AI researcher, then the direct harm starts to become relevant compared to opportunity costs.

Yeah, my current model is that WebGPT feels like some of the most timelines-reducing work that I've seen (as has most of OpenAIs work). In-general, OpenAI seems to have been the organization that has most shortened timelines in the last 5 years, with the average researcher seeming ~10x more efficient at shortening timelines than even researchers at other AGI companies like Deepmind, and probably ~100x more efficient than researchers at most AI research organizations (like Facebook AI).

WebGPT strikes me on the worse side of OpenAI capabilities research in terms of accelerating timelines (since I think it pushes us into a more dangerous paradigm that will become dangerous earlier, and because I expect it to be the kind of thing that could very drastically increase economical returns from AI). And then it also has the additional side-effect of pushing us into a paradigm of AIs that are much harder to align and so doing alignment work in that paradigm will be slower (as has I think a bunch of the RLHF work, though there I think there is a more reasonable case for a commensurate benefit there in terms of the technology also being useful for AI Alignment).

I moved that thread over the AIAF as well!
