I'm worried that it will be hard to govern inference-time compute scaling.
My (rather uninformed) sense is that "AI governance" is mostly predicated on governing training and post-training compute, with the implicit assumption that scaling these will lead to AGI (and hence x-risk).
However, the paradigm has shifted to scaling inference-time compute. And I think this will be much harder to effectively control, because 1) it's much cheaper to just run a ton of queries on a model as opposed to training a new one from scratch (so I expect more entities to be able to scale inference-time compute) and 2) inference can probably be done in a distributed way without requiring specialized hardware (so it's much harder to effectively detect / prevent).
Tl;dr the old assumption of 'frontier AI models will be in the hands of a few big players where regulatory efforts can be centralized' doesn't seem true anymore.
Are there good governance proposals for inference-time compute?
By several reports, (e.g. here and here) OpenAI is throwing enormous amounts of training compute at o-series models. And if the new RL paradigm involves more decentralized training compute than the pretraining paradigm, that could lead to more consolidation into a few players, not less, because pretraining* is bottlenecked by the size of the largest cluster. E.g. OpenAI's biggest single compute cluster is similar in size to xAI's, even though OpenAI has access to much more compute overall. But if it's just about who has the most compute then the biggest players will win.

I think those governance proposals were worse than worthless anyway. They didn't take into account rapid algorithmic advancement in peak capabilities and in training and inference efficiency. If this helps the governance folks shake off some of their myopic hopium, so much the better.
