Former DeepMind researcher founds Metis Reasoning
What happened
On 27 October 2026, The Decoder reported that former DeepMind researcher Thore Graepel has founded Metis Reasoning, proposing an AlphaGo-inspired approach to curbing hallucinations in large models. The method uses an explicit knowledge ledger recording what is known, confidence levels and open questions, with an independent module verifying steps against computation, formal proof or empirical evidence; a reasoning step must pass inspection before it can change the knowledge state. The report so far covers only the method's concept and does not disclose the company's funding, team size or product progress.

- The DecoderFormer Deepmind researcher thinks AlphaGo's playbook can cure AI hallucinations
Former Deepmind researcher Thore Graepel wants his startup Metis Reasoning to bring AlphaGo's search principle to general reasoning. Instead of locking knowledge inside model weights, an explicit knowledge ledger would make every conclusion checkable against evidence. So far, though, there's no working system and no benchmarks.
