The Download: how to tell when a chatbot is lying, and RIP my biotech plants
How it works: The Trustworthy Language Model gives any output generated by a large language model a score between 0 and 1, according to its reliability. This lets people choose which responses to trust and which to throw out. In other words: a BS-o-meter for chatbots.
