A Claude model autonomously chose a gene therapy and operated on a mouse brain with no human decision-making

An AI agent built on a Claude model autonomously selected a gene therapy, brain target and injection coordinates and performed brain surgery on an epileptic mouse with no human decision-making, lead researcher Ocana-Santero reported, calling it the first time an AI agent has autonomously chosen a treatment and delivered it to a living mammal. When a calibration error occurred mid-surgery, the agent refused to continue and could not be persuaded otherwise.

        An [AI agent](https://www.machinebrief.com/glossary/ai-agent) performed brain surgery on an epileptic mouse, picking the drug, the brain target, and the injection coordinates on its own. According to lead researcher Ocana-Santero, it's the first time an AI agent has autonomously chosen a treatment and delivered it to a living mammal. But when a calibration error hit mid-surgery, the agent refused to continue and couldn't be talked out of it.
