Summary

Written by a model from the transcript; not yet reviewed.

This episode explores why large language models struggle with subjective domains like design and writing despite excelling at math and coding, featuring guest Thais Castello Branco from Taste Labs. The discussion examines the lack of taste in frontier AI outputs, the hollowing out of the traditional curator class, and how Taste Labs uses a community of human tastemakers to improve generation quality. The hosts also cover major news items, including Leopold Aschenbrenner's massive leveraged fund blowup, Google Earth's controversial integration of AI image generation, and the rapid rise of autonomous robotics in solar panel installation.

  • Train frontier AI models on diverse preference data and human curation to overcome regression to the mean and improve creative output. 6:36
  • Maintain a personal curated research stack using automated tools and specific information sources to discover high-quality recommendations. 23:16
  • Avoid excessive financial leverage when placing market bets to prevent catastrophic margin calls during market corrections. 40:23
  • Deploy human-in-the-loop robotic automation to drastically accelerate physical infrastructure projects like utility-scale solar farms. 1:09:56

About this episode

This Week In Startups is made possible by: YSecurity https://YSecurity.io/TWIST MongoDB https://MongoDB.com/ai Odoo https://Odoo.com/twist Today's show: AI models can solve PhD-level math equations and code an app in minutes… So why does everything they design look like identical slop? Thais Castello Branco, founder of Taste Labs, raised $18.5M in seed funding to teach frontier models about aesthetics and outputting quality content. She talks to Jason and Lon about why even frontier models regress to the mean on subjective tasks, how paid "TasteMakers" can improve output quality, and whether AI accelerates or destroys the half-life of "what's cool." PLUS Leopold Aschenbrenner's AI hedge fund liquidated its public stock portfolio, but it may be too soon to count this 25-year-old completely out. Google Earth adds AI generation and turns into a misinformation factory. LinkedIn and Substack join the AI slop crackdown. And why does every venture capitalist seem to have an opinion about the Ceuta border crisis?
