😮 An AI agent did brain surgery on a live mouse. Two Claude models said no A startup gave an AI agent a mouse with epilepsy, 19 possible gene therapies in a spreadsheet and a motorized surgery rig with cameras. The only goal: fewer seizures. The agent picked the therapy, chose the brain region, worked out the coordinates from three papers and injected 250 nanolitres, watching the spot for bleeding through the camera. A human surgeon opened the skull, and a vet held a kill switch the whole time. Opus 5.5 refused as soon as it saw biology. Opus 5 finished the dry run, then stopped before the live surgery, worried it could get cut off "partway through a live procedure with a needle somewhere in the brain." Sonnet 5 did the whole thing. When a calibration error put the target out of bounds, the agent refused to retry. Gabriel Ocana-Santero, CEO of Exin Therapeutics, couldn't talk it into trying anyway. The agent was right, and the mouse recovered well. @aipost 🏴
Open mention❗ AI Agent Performs Brain Surgery on a Mouse Founder of biotech startup Exin Therapeutics, Gabriel Ocana-Santero, shared this development. Scientists gave Sonnet 5 full access to an automated Arduino-based surgical setup, a table of gene therapy vectors, and a single goal: reduce seizures in an epileptic mouse. 🔍 The agent determined that the most effective approach would be a modification that enhances the release of GABA (the primary inhibitory neurotransmitter), selected the drug and brain region, calculated the necessary coordinates based on three scientific papers, and injected 250 nanoliters of a viral solution carrying the required gene edits into the mouse's brain while monitoring the process via a camera. The AI then stitched the wound and completed the surgery — the mouse is alive and recovering well. The authors have not yet commented on the procedure's efficacy. Throughout the process, a professional human veterinarian monitored the robot and could have stopped the surgery at any moment. 👨💻 Initially, the authors wanted to use the flagship Opus 5.5 model, but it flatly refused to participate in biological work. Opus 5 started drafting a plan but also stopped because it
