Clinic runs on Mac Studio: Dr. 村岡洋典 builds in-house local LLM

The post by X user Tokoroten, which quoted the clinic's notice, drew reactions such as "cutting-edge" and "maybe it's cheaper than medical equipment," and has passed 590,000 views. The clinic's own notice frames the work as improving care quality and operational efficiency, and it tells patients who do not want their information taken into the in-house AI to say so at reception.

GENSHI AI's representative Daichi Nagashima, whose company builds local LLM environments for medical settings, said the business is just starting but has drawn more than 20 inquiries. He said the strongest on-site demand is for transcribing and summarizing voice during medical interviews and transferring it to charts, because exam content full of private patient information can be processed by AI without leaving the facility. The company says its setup keeps inference inside the clinic's closed network and follows the government's "3 Ministry 2 Guideline" rules for handling medical information.

The Mac Studio the clinic installed starts at about 420,000 yen for the cheapest model with the M5 Max chip and 36GB unified memory, rising to about 950,000 yen with the M5 Ultra chip and 96GB unified memory, according to the article. Through a vendor, it is hard to call this cheaper than medical equipment, and whether ordinary clinics follow may hinge on whether these setups become affordable and easy enough for staff without engineering backgrounds.
