Brief paper announcement (longer thread might follow): In our new paper "Modeling Human Beliefs about AI behavior for Scalable Oversight", I propose to model a human evaluator's beliefs to better interpret the feedback, which might help for scalable oversight. (1/4)

I notice more “big” accounts here that follow a lot of people. The same accounts follow almost no one on twitter. Is this motivated by a difference in the algorithms of these platforms?

Yet another safety researcher has left OpenAI. Rosie Campbell says she has been “unsettled by some of the shifts over the last ~year, and the loss of so many people who shaped our culture”. She says she “can’t see a place” for her to continue her work internally.

Does anyone understand why it’s so easy to clone twitter with no IP issues? It’s hard to understand qualitative legal thresholds, but the UI looking ~exactly the same both here and on threads intuitively seems like the kind of thing that could violate a copyright if twitter had pursued one

the success of Bluesky with an absolutely tiny team does sorta prove Musk had a point about Twitter having way too many staff
