AI Models Can Provably Hide Arbitrary Capabilities

Contramont Research, Oxford and ACS Research authors hid an encrypted small neural network in model weights that runs only on a secret trigger. In small purpose-built models (a chemistry classifier standing in for dangerous skills), fine-tuning and other probes failed to surface it. The authors call it a proof of concept, not a turnkey attack; its presence may be detectable.
