    Jasper Gilley: The Brain Region That Predicts Your Own Thoughts

    Jasper Gilley is a member at South Park Commons researching new AI architectures inspired by how the brain works - specifically the cerebellum, and what it would take for a model to introspect on its own computation the way humans do for free. Before that he was at Yutori, building vision-based web agents that emulate human users. We get into why models need expensive post-hoc interpretability while humans can dissect their own thinking automatically, his forward self-modeling work (training a deliberately undersized model to predict a transformer's own activations, then reading the residual as a novelty signal), why weighting grokking data by Zipf's law turns training into an infinite oscillator that discovers the solution and forgets it forever, why vision beats the DOM for browser agents, why software is an "exoskeleton of intelligence" and demand for it is still elastic, and what humans were actually evolutionarily designed for. Chapters: 0:00 Cold open 1:02 Intro 1:43 Researching brain-inspired architectures at South Park Commons 4:05 The cerebellum as a forward model 6:39 The Forward Self-Modeling paper 14:03 Grokking, explained 18:37 Zipfian Grokking: finding the solution and forgetting it 22:26 Yutori: why vision beats the DOM 31:23 Why Jevons' Paradox won't save your software engineering job 41:51 The window where creativity is the whole job 45:39 What humans were evolutionarily designed for 51:09 The future of post-training

    Ryan Tsang: How to Ship AI Agents When Failure Isn't an Option

    Ryan Tsang is building Harmonize Health - an AI-native operating system for medical clinics. Ryan spent four years at Microsoft working on Azure OpenAI's fine-tuning product, then trained models for open-source AI safety benchmarks at MLCommons. We get deep into how Harmonize Health builds and grades evals for voice agents (including a user-simulator agent that role-plays the patient calling in), why you should get to production before you build the perfect eval set, how Harmonize scrubs patient data out of transcripts, and the tension between forward-deployed engineering and scaling across multiple clinics. Hope you enjoy the third episode of The Interlude Show! Chapters: 00:00 - Move fast and break things doesn't work in healthcare 00:41 - Meet Ryan Tsang and what Harmonize is building 02:40 - Why healthcare, and the path from pre-med to CS 05:45 - Inside a primary care clinic: the work nobody sees 10:50 - Safety is the hardest technical problem 13:55 - Data plumbing vs. AI: EHRs and tribal knowledge 20:36 - Encoding a clinic's operating procedures into agents 23:35 - Inside their eval harness for voice agents 27:07 - What can we really not screw up? 30:16 - Healthcare moves at the speed of trust 38:57 - TempShot: pitching his high school app to us as VCs 49:53 - The YC all-nighter, quitting our jobs, and why compounding wins
