| ChatGPT did not lie; it cannot lie. It was given a sequence of words and tasked with producing a subsequent sequence of words that satisfy with high probability the constraints of the model. It did that admirably. It's not its fault, or in my opinion OpenAI's fault, that the output is being misunderstood and misused by people who can't be bothered understanding it and project their own ideas of how it should function onto it. |
Large Language Models (LLMs) are never wrong, and they do not make mistakes. They are not fact machines. Their purpose is to abstract knowledge and to produce plausible language.
GPT-4 is actually quite good at handling facts, yet it still hallucinates facts that are not common knowledge, such as legal ones. GPT-3.5, the original ChatGPT and the non-premium version, is less effective with even slightly obscure facts, like determining if a renowned person is a member of a particular organization.
This is why we can't always have nice things. This is why AI must be carefully aligned to make it safe. Sooner or later, a lawyer might consider the plausible language produced by LLMs to be factual. Then, a politician might do the same, followed by a teacher, a therapist, a historian, or even a doctor. I thought the warnings about its tendency to hallucinate speech were clear — those warnings displayed the first time you open ChatGPT. To most people, I believe they were.
