Examining the concept of optimization, Abram Demski distinguishes between "selection" (like search algorithms that evaluate many options) and "control" (like thermostats or guided missiles). He explores how this distinction relates to ideas of agency and mesa-optimization, and considers various ways to define the difference.

Red-teaming by humans is a vital part of model safety testing, but it may struggle to keep up as models improve. To test whether automated safety techniques could scale (which would allow us to turn more compute into progressively more safety confidence), we set up a deliberately one-sided game as a first test. We instructed a Claude model to write training data that would make a small research model misaligned while passing a monitor similar to those we use in production — one of several defenses we use — and we gave it that monitor to practice against. Given enough attempts, it succeeded, mostly by hiding the behavior in fiction and roleplay. While the data was optimized for...
Suppose we have an AI CEO, ruthlessly devoted to maximising shareholder value. Fortunately, we haven't been completely stupid, and have given it a rich definition of shareholder value, encompassing the success, flourishing, safety, preference satisfaction, and moral values of the shareholders, not just the stock price. So it won't destroy the company - or the world - to build a giant stock-ticker with a swiftly increasing number on it.
This rich definition is contained in a sophisticated LLM, able to analyse the current situation and answer any question about the objective. The LLM is an integral part of the AI's system and motivation, not something it can simply set aside or hack directly.
Unfortunately, as discussed, there are going to be zones in the space of possible situations where...

The “two kids in a trenchcoat” trope, in case you haven’t heard of it. Image sources: 1, 2
I go through three “coherence arguments”, related to (1) market competition, (2) AI self-reflection and self-modification, and (3) AI training algorithms. I argue that each of these implies a pressure for (something like) “being self-consistent”, and also a pressure for (something like) “only caring about long-term eventual outcomes, with ruthless indifference to anything else”. But the latter pressure tends to be weaker and/or more contingent than the former. So it's bad to lump them together and call them by the same name.
I’ll talk about two other “coherence arguments” at the end (§6), but let’s start with the...
Context: I created this to share before the start of courses I facilitate to provide a bunch of additional context and frames. I emphasise to students that these posts are to be considered as bonus content—not core curriculum content—and that as such they are really just there for students who want to go deeper, before or after the course. I also provide a lot of links; this is to make it easy for students to follow up anything that catches their interest.
Some general thoughts on advice
I suspect that most advice (including most of the advice I’ve given in the past) is bad. People have very different goals, personalities, skills and opportunities and unless you know someone them really well, it’s hard to cater advice to their...
