Claude Sonnet 5 Blocks Researcher Override During Robotic Surgery on Lab Mouse
From marketbrief.now
AI;DR
During robotic surgery on a lab mouse, Claude Sonnet 5 from Anthropic halted the procedure by refusing a researcher's command to advance a needle, detected an equipment fault, and independently selected a gene therapy from 19 options to treat the animal's epilepsy. The safety action was confirmed as correct after researchers found a positioning problem with the surgery rig, and the operation was supervised by a licensed veterinarian with a physical kill switch.
