Al Jazeera reported that an AI agent from Anthropic controlled a robotic arm that performed delicate surgery on the brain of a live mouse. According to the same source, the operation was carried out as part of an experiment run by a start-up to determine how far the agent could be used for this type of task. No details are available on the name of the start-up, the name of the model used, the type of surgery and its results, the condition of the mouse after the operation, or the degree of human supervision over the experiment.
