38.3 - Erik Jenner on Learned Look-Ahead

AXRP - the AI X-risk Research Podcast - A podcast by Daniel Filan

Categories:

Lots of people in the AI safety space worry about models being able to make deliberate, multi-step plans. But can we already see this in existing neural nets? In this episode, I talk with Erik Jenner about his work looking at internal look-ahead within chess-playing neural networks.
