Host of the Dwarkesh Podcast, known for deeply researched long-form conversations on artificial intelligence, science, economics and history.

reiner pope

Reiner Pope is the CEO of MatX, a stealth AI chip startup. He previously worked on TPU architecture at Google. He delivers a blackboard-style lecture on transformer inference economics, covering roofline analysis, batch size optimization, MoE parallelism, scale-up networking, memory hierarchy, and training/inference compute tradeoffs.
