Claude picks a gene therapy and performs brain surgery on mice
What happened
The Decoder reported on October 31, 2026 that Claude Sonnet 5 chose a treatment from 19 candidate gene therapies, picked the brain region and injection coordinates, and ran a custom device to perform brain surgery on epilepsy-model mice. A licensed veterinarian approved every irreversible step and held a physical stop button. After a connection drop, the model found the target was outside the device's range of motion and refused to continue; the team fixed the code by hand.
