Can Language Models Lie? | WebGPT, DeepMind Retro, and The Challenge of Fact-Checking in LLMs

The video discusses the challenges of generating factually accurate text with language models, highlighting that these models are optimized to mimic human-like text rather than ensure factual correctness. It explores the sources of data used for training, such as Wikipedia and Reddit, and the inherent issues with accuracy. The video introduces datasets like Truthful QA and ELI5 for testing model accuracy and discusses approaches by DeepMind and OpenAI to integrate fact-checking. It also compares WebGPT's performance with human responses and addresses ongoing challenges in fact-checking and human evaluation.
