Former Deepmind researcher thinks AlphaGo's playbook can cure AI hallucinations

Former Deepmind researcher Thore Graepel founded Metis Reasoning, which proposes applying AlphaGo's approach of pairing neural networks with systematic search to general reasoning, using an explicit "knowledge ledger" that records what is known and checks new entries against evidence. Metis says the setup should produce fewer hallucinations and knowledge that can be changed without retraining, though the white paper describes only a research program with no working system or benchmarks. Graepel, who worked on AlphaGo, AlphaZero and MuZero, is reportedly raising a low tens-of-millions round for Metis.
