This is the weekly visible open thread. Post about anything you want, ask random questions, whatever. ACX has an unofficial subreddit, Discord, and bulletin board, and in-person meetups around the world. 95% of content is free, but for the remaining 5% you can subscribe here. In this week’s news:

1: Solenoid_Entity, who runs the ACX Podcast, is expanding his empire to run a Less Wrong Curated Podcast and Metaculus Journal Podcast. Good luck, Solenoid!

2: More volleys in recent AI conversations: Cameron Bucker (“debates in deep learning are now repeating the same mistakes as comparative psychology”), Edwin Chen (how do humans do on the same questions Gary Marcus asked GPT?), and a new paper, Emergent Abilities Of Large Language Models (formalizing the insight that as models scale up, they can do completely new types of tasks, not just the old tasks better).

3: Related: does anyone reading this have access to the new Parti-20B image model from Google? I would like to check whether I have won my bet with Vitor about image model progress. If yes, I will write a post about it and give you good publicity.

4: In Obscure Pregnancy Interventions, I mentioned a Mongolian study found that air purifier use during pregnancy increased birth rate, but that nobody had tested yet whether it increased later-life IQ. Those results are now in and it appears that it does. Caveats mentioned on the subreddit: only marginally significant, your area is probably less air polluted than Mongolia, normal air conditioners might work as air purifiers already.
