## Summary

Thore Graepel, a former DeepMind researcher, says his startup Metis Reasoning will build AI systems that keep an explicit knowledge ledger and check each conclusion against evidence, rather than storing knowledge in model weights. Metis describes the approach as a research program with no working system, benchmarks, or comparisons with current reasoning models. Bloomberg reports Graepel is raising a low tens-of-millions round, with a follow-on of several hundred million dollars at a higher valuation already in the works.
