Mitigating Reward Hacking as Institutional Design
Epistemic status: Obviously speculative but mechanism design is fun. Last year I wrote a post on reward hacking as we were then beginning to see concerning signs of scaling RLVR causing models to exhibit substantial reward hacking behaviours. Unfortunatel

Scaling is subtler than it seems
Epistemic status: A lot of this is vibes and generally trying to express tacit knowledge from ML experience and training models. However there are a huge number of details here and the field of ML changes incredibly rapidly. This is an oversimplified, but

Maximum Entropy Morality, Metaplastic Constitutionalism, and the Dynamic Virtues
Author's note: This is quite a long post. It is highly speculative, obviously, but I think it offers an interesting perspective on, and proposal for, outer alignment. The specific idea here is to move away from demanding a final lightcone-scale conception

How can LLM RL Work Despite Information-Theoretic Inefficiency
Epistemic Status: Obviously speculative and maybe obvious. The success of RL in LLMs has been puzzling me for a while. People have developed various information-theoretic style arguments by which they argue that RL is extremely informationally inefficient

Autarkic Agency Will Likely Migrate Upwards
Epistemic status: Interesting as a mechanism and trend, but obviously highly variable over short timescales and ultimately speculative. On a plane recently I ended up noodling back around to my original concepts of amortised vs direct optimization and als

Baudrillard and Interiority
Epistemic Status: I really only did a fairly surface level skim of Baudrillard's actual work mostly cribbed from secondary sources, so I could very well be misrepresenting core things about what he actually said. On the other hand, Baudrillard really just

Taking the Singularity Seriously
Author's note: More mystical than usual. A vibe rather than a point. The earliest prophets, Good and Vinge, predicted the existence of such a singularity. They sketched the first field equations and were the first to see the truth that time must end, not

Understanding Functional Decision Theory as Program Search
Epistemic note: Probably already known or obvious, but this treatment seems clearer to me than the standard treatment in e.g. the FDT paper. The other day I went down a deep lesswrong rabbit-hole and ended up going through all the decision theory literatu
