Advanced AI chatbots are less likely to admit they don’t have all the answers

Researchers have spotted an apparent downside of smarter chatbots. Although AI models predictably become more accurate as they advance, they’re also more likely to (wrongly) answer questions beyond their capabilities rather than saying, “I don’t know.” And the humans prompting them are more likely to take their confident hallucinations at face value, creating a trickle-down effect of confident misinformation. “They are answering almost everything these days,” José Hernández-Orallo, professor at the Universitat Politecnica de Valencia, Spain, told Nature. “And that means more correct, but also more incorrect.” Hernández-Orallo, the project lead, worked on the study with his colleagues at the Valencian Research Institute for Artificial Intelligence in Spain. The team studied three LLM families, including OpenAI’s GPT series, Meta’s LLaMA and the open-source BLOOM. They tested early versions of each model and moved to larger, more a
