summary: "GPT-6.1 Sol and Grok 4.7 selected different gene therapy mechanisms and brain injection coordinates in robotic brain surgery tests. Claude Sonnet 5 analyzed three research papers and 19 therapy vectors to deliver a 250 nanoliter injection. Gabriel Ocana-Santero, cofounder of San Francisco startup Exin Therapeutics, conducted the tests using a motorized surgical rig."
