🚨 New preprint alert:
We show that web-browsing GPT and LLaMA models can infer social media user demographics with reasonable accuracy—using only usernames.
This opens new possibilities for social media research in the post-API era but raises important privacy concerns.

FreshLLMs: Refreshing Large Language Models with Search Engine Augmentation
Most large language models (LLMs) are trained once and never updated; thus, they lack the ability to dynamically adapt to our ever-changing world. In this work, we perform a detailed study of the...
