Read the parent of the parent. Its about being able to answer questions thats not in its training data. People are talking about LLMs making scientific discoveries that humans havent. A ridiculous take. Its not possible and with the current state of tech never will be. I know what LLMs are trained on. Thats not the topic of conversation.
People don't think that. Especially not the commentor you replied to. You're human-hallucinating.
People think LLM are trained on raw documents and code besides StackOverflow. Which is very likely true.
