I'm normally not one for breathless excitement about AI advances, but this video breakdown of the 22 Mar paper
Sparks of Artificial General Intelligence:
Early experiments with GPT-4[1] really surprised me as to the extent to which LLMs like GPT-4 have advanced. The paper shows that GPT-4 can use tools and assemble results into an answer, solve Leetcode mediums and even an IMO 2022 problem, generate full code for a video game based on a high-level description, and display a theory of mind (modeling what others are thinking). This is pretty amazing (and frankly frightening) progress.
