Former DeepMind researcher proposes AlphaGo search mechanism to reduce AI hallucinations

Former DeepMind researcher Thore Graepel founded Metis Reasoning to apply AlphaGo's search-based reasoning to general AI. The approach introduces an explicit knowledge ledger that records what the system knows and which questions remain open, separate from model weights. A verification module checks conclusions against evidence, and reasoning steps are only applied if independently validated, aiming to reduce hallucinations and enable source-cited explanations.
