OpenAI's ChatGPT has taken the world by storm with its ability to generate human-like responses based on a vast general knowledge base. Large language models (LLMs) like GPT-4 are voracious readers, having read everything from Wikipedia to internet content. They build statistical models of language by measuring which words are often used together across different types of texts and learning higher level concepts. However, current limitations prevent them from fully understanding deeper meanings of language or solving mathematical problems. Efforts are being made to improve these models' comprehension capabilities.
