What's next after RLHF?
RLHF was a massive commercial success: roughly 100% of LLM usage is through RLHF’d models - but it was in many ways also a research failure. Let’s talk about how it conquered the world, how it defied its creators expectations, why AI is in the bimodal state it’s in (is it a bubble or a machine god?), and how to make AI actually transform the economy.
