Ex-DeepMind researcher launches London reasoning lab Metis Reasoning
Thore Graepel, who helped build Google DeepMind’s AlphaGo, has launched Metis Reasoning in London. The lab says its approach combines explicit knowledge, evidence-based judgments and AlphaGo-inspired search, with the goal of making reasoning more auditable than standard LLM outputs. Its white paper “The Age of Reasoning” presents no test results or released model, and co-founder Piers Ingram said only that early results on frontier reasoning problems were “encouraging.”
Metis is pursuing a distinct research direction centered on inspectable, search-based reasoning rather than simply scaling larger language models, although its performance and efficiency claims remain unverified.

Metis Reasoning
Key Points
- Former Deepmind researcher Thore Graepel founded Metis Reasoning to make AI systems more reliable and verifiable, using AlphaGo's approach as a blueprint.
- The method separates knowledge from model weights and stores it in an external ledger, where an independent module checks every assumption against evidence.
- The approach aims to cut hallucinations and provide source-backed explanations, but so far it exists only as a theoretical framework with no working system.
