DeepMind AI with built-in fact-checker makes mathematical discoveries

Google DeepMind claims to have made the first ever scientific discovery with an AI chatbot by building a fact-checker to filter out useless outputs, leaving only reliable solutions to mathematical or computing problems. Previous DeepMind achievements, such as using AI to predict the weather or protein shapes, have relied on models created specifically for the task at hand, trained on accurate and specific data. Large language models (LLMs), such as GPT-4 and Google's Gemini, are instead trained on vast amounts of varied data to create a breadth of abilities. But that approach also makes them susceptible to "hallucination", a term researchers use for producing false outputs. Gemini – which was released earlier this month – has already demonstrated a propensity for hallucination, getting even simple facts such as the winners of this year's Oscars wrong.
