Exin Therapeutics Has an AI Agent Perform Brain Surgery on a Mouse to Treat Epilepsy
English text is being prepared.
Biotech startup Exin Therapeutics says it has had an AI agent complete brain surgery on a mouse with epilepsy. The team used an Anthropic Sonnet model and provided a spreadsheet of 19 gene therapy vectors, an epileptic mouse model, and a robotic arm setup with a camera; the model autonomously selected the drug and brain region, derived coordinates from three papers, and drove the robotic arm to inject 250 nanoliters of the drug, while the craniotomy and suturing were performed by human doctors. The company had originally preferred Anthropic Opus 5.5, but that model refused to carry out the task after detecting biologically related content, and reasoned about the consequences of stopping midway.

The report presents the process by which the agent autonomously selected drugs, located the target, and injected during live surgery, and also records details of the model refusing to carry out the task due to risk assessment.

让AI自己做脑部手术,初创公司成功让智能体给小鼠治疗癫痫IT之家下载客户端 独家抢先看2026年11月01日 15:20:39 来自山东Updated 2026年11月01日 15:41:55
IT之家 11 月 1 日消息,专注于下一代神经治疗的生物科技初创公司 Exin Therapeutics 本周声称,该公司已成功让 AI 智能体对一只小鼠进行了脑部手术。
该公司联合创始人兼首席执行官 Gabriel Ocana-Santero 在 X 平台上分享了整个过程,展示了 AI 智能体如何选择基因治疗载体、剂量以及应用的大脑区域。
该团队使用了 Anthropic Sonnet 模型进行手术,给了模型一个电子表格(其中有 19 种基因疗法载体)、一个癫痫小鼠模型、一个带摄像头的机械臂手术装置,以及一个目标:减少癫痫发作。
模型自主选择了药物,选择了脑区,从三篇论文中推导出坐标,然后驱动机械臂给小鼠大脑做手术,同时通过装置摄像头观察注射部位是否有出血,最后注射了 250 纳升药物。
IT之家从该公司披露了解到,AI 只负责了注入药物的过程,开颅和缝合都是真人医生做的。此外,该公司原本首选使用 Anthropic Opus 5.5 模型,然而 Opus 5.5 一旦检测到生物相关内容,就立即拒绝。
Opus 5.5 输出称:“这个障碍不是设备,也不是输入。是我的问题。我自己的输出在开始编写手术计划时就被停止了…… 如果我尝试,它会以同样的方式被截断,最糟糕的情况是我在活体手术中途被截断,而针还留在大脑的某个地方。在麻醉动物身上开始一个我无法完成的事情,比不开始更糟糕。”
也就是说该模型拒绝了任务,因为它觉得自己可能无法完成手术,并推理了如果中途停止带来的后果。
