Alex Zhu spent quite awhile understanding Paul's Iterated Amplication and Distillation agenda. He's written an in-depth FAQ, covering key concepts like amplification, distillation, corrigibility, and how the approach aims to create safe and capable AI assistants.
I sometimes think about plans for how to handle misalignment risk. Different levels of political will for handling misalignment risk result in different plans being the best option. I often divide this into Plans A, B, C, and D (from most to least political will required). See also Buck's quick take about different risk level regimes.
In this post, I'll explain the Plan A/B/C/D abstraction as well as discuss the probabilities and level of risk associated with each plan.
Here is a summary of the level of political will required for each of these plans and the corresponding takeoff trajectory:
Last week, Thinking Machines announced Tinker. It’s an API for running fine-tuning and inference on open-source LLMs that works in a unique way. I think it has some immediate practical implications for AI safety research: I suspect that it will make RL experiments substantially easier, and increase the number of safety papers that involve RL on big models.
But it's more interesting to me for another reason: the design of this API makes it possible to do many types of ML research without direct access to the model you’re working with. APIs like this might allow AI companies to reduce how many of their researchers (either human or AI) have access to sensitive model weights, which is good for reducing the probability of weight exfiltration and other rogue...
Imo a significant majority of frontier model interp would be possible with the ability to cache and add residual streams, even just at one layer. Though caching residual streams might enable some weight exfiltration if you can get a ton out? Seems like a massive pain though
Anthropic, GDM, and xAI say nothing about whether they train against Chain-of-Thought (CoT) while OpenAI claims they don't[1].
I think AI companies should be transparent about whether (and how) they train against CoT. While OpenAI is doing a better job at this than other companies, I think all of these companies should provide more information about this.
It's particularly striking that Anthropic says nothing about whether they train against CoT given their system card (for 4.5 Sonnet) is very thorough and includes a section on "Reasoning faithfulness" (kudo...

Before we observe scheming, where models covertly pursue long-term misaligned goals, models might inconsistently engage in various covert behaviors such as lying, sabotage, or sandbagging. This can happen for goals we give to models or they infer from context, or for simple preferences they acquire from training — something we previously found in Frontier Models Are Capable of In-Context Scheming.
In a new research collaboration with OpenAI, we developed a larger suite of alignment evaluations for covert actions (26 evaluations) and studied a training method to reduce such covert behaviors. We manage to significantly reduce (by ~30x; OpenAI o3: 13.0%→0.4%; OpenAI o4-mini: 8.7%→0.3%) the rate of covert actions across our diverse suite by only training against a single type of...
Thanks for the detailed response!
"If your life choices led you to a place where you had to figure out anthropics before you could decide what to do next, are you really living your life correctly?"
To revisit our premises: Why should we think the end result is achievable at all? Why should it be possible to usefully represent the universe as an easily interpretable symbolic structure?
First, I very much agree with the sentiment quoted above, so we aren't quite doing that here. Most of the actual reason is just: it sure looks like that's the case, empirically. As I'd argued before, human world-models seem autosymbolic, and the entirety of our (quite successful) scientific edifice relies on something-like-this being true. I think the basic case is convincing enough not to require...
Some new data on that point:
Maybe if lots of noise is constantly being injected into the universe, this would change things. Because then the noise counts as part of the initial conditions. So the K-complexity of the universe-history is large, but high-level structure is common anyway because it's more robust to that noise?
To summarize what the paper argues (from my post in that thread):
...
- Suppose the microstate of a system is defined by a (set of) infinite-precision real numbers, corresponding to e. g. its coordinates in phase space.
- We define the coarse-grai
Maybe I should clarify my view a bit on Plan A vs "shut it all down":
