The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 10 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable

Kaplan: AI training and inference will see 3x-10x yearly efficiency gains
“I think that over time, as AI becomes more and more widespread, I think that we're going to really drive down the cost of inference and training dramatically from where we are right now. Sort of, three X to 10 X gains algorithmically, and in sort of scaling up…”

Habib: Anthropic matched RLHF performance using AI-generated feedback

Joseph: Public estimates placed GPT-3 training cost at $5 million
“Like the public estimates for GP three, I remember, were that it cost five million dollars to train, which you're like, on the one hand, five million is kind of a lot, but it's like a lot for an individual person. It's not really a lot from like a company pers…”
