Exin Therapeutics says an AI agent injected gene therapy into a live mouse’s brain

Exin Therapeutics says an AI agent selected a gene therapy from 19 options and controlled robotic arms and an injector needle to deliver the treatment into the brain of a live mouse with epilepsy. According to Wired, a veterinary surgeon first performed the craniotomy, while the agent selected the brain region, coordinates, and parameters such as injection volume and speed.

The experiment was conducted by Gabriel Ocana Santero, the startup’s cofounder and CEO, to test how agents can interact directly with laboratory equipment. The team initially tested Claude Opus 5.5, which refused to guide the needle, and then used Claude Sonnet 5. The system required human approval of the injection plan, included an emergency button, and could not modify the equipment’s code; however, a technical glitch disrupted the coordinate system, Wired reports.
