@danluu fuzzing must be great but how do you develop anything about it? It's a bogeyman for codex. As soon as your agent mentions "fuzzing", regardless of the context, you get blocked immediately 😤 @thsottiaux

People are worried about fully automated companies, I think for good reasons. What about fully automated non-profits and charities, would that be good or dystopic?

I think §5.4, building new and adapting old institutions, at large scale, is what a large fraction of OpenAI's foundation and Anthropic's wealth should be directed to. Technical AI safety and biorisk mitigation can absorb maybe up to ~10B/year each, but not ~100B/year.

If anyone builds it, everyone thrives. Over the past decade, a lot of important work on AI alignment has focused on avoiding harm. But freedom from harm isn't the same as freedom to flourish. In this paper, we introduce 'Positive Alignment'. A positively aligned agent is one

This post is more signal about real agent autonomy than the notorious METR chart. I've also run ~30h hour goal with little steering and can corroborate: GPT-5.5-xhigh loses the plot badly. Prioritisation/big picture grasp/engineering common sense are at junior level still.

I know everything is a skill issue, but I didn't have a good experience with /goal in Codex CLI. I tried giving it 2 tasks, that were hard but well specified. 1) Build a video stabiliser on top of open source to match the Google Photos stabiliser in quality. I had a starter and

So far, I definitely see a lot of practical engineering judgement regressions between gpt-5.4 and gpt-5.5. I'm not very impressed. The 'leash' couldn't be made longer than it used to be for 5.4
