A good person to follow if you care about what deployment-minded safety work looks like inside a frontier lab, especially around moderation, image systems, and system-card style evaluation.
4 sources
A high-signal person to follow for the evaluation and verification side of alignment, especially where language models are pushed to produce answers that can actually be checked rather than merely sounding plausible.

A useful person to follow for the connection between classic multi-agent RL and the human-feedback work that later fed into OpenAI’s instruction-following systems.
3 sources
One of the clearest people to study for the early OpenAI RLHF stack, especially where human feedback moved from summarization experiments into general instruction-following systems.
