Elon Musk‘s latest venture has sparked both excitement and concern in the healthcare community. The AI chatbot, Grok, is being promoted as a tool for medical analysis. The X (formerly Twitter) founder is now encouraging people to use Grok AI to analyze medical scans and get a second opinion.
Elon Musk rallies for Grok to be used as a medical tool
Elon Musk is pushing for Grok to be used as a medical diagnostic tool, encouraging users to upload their medical scans for analysis.
Musk has thrown his weight behind Grok 4.20, reposting a post on X that praised the AI chatbot’s analyzing ability. The post highlighted Grok 4.20’s capability to analyze blood tests and medical scans.
The original post by DogeDesigner called Grok 4.20 “insanely good and quick” at analyzing blood tests. The post says that users can upload lab reports or MRI images for detailed analysis. Musk’s update has garnered massive attention, with over 4 million views within an hour.
However, this isn’t the first time Elon Musk has promoted Grok, his AI chatbot, for medical analysis. In October 2024, he urged people to upload their medical scans to Grok, claiming it was “already quite accurate”. Additionally, in January 2026, a resurfaced video showed Elon Musk claiming he had“seen cases where it’s actually better than what doctors tell you.”
However, experts are raising concerns about accuracy and data safety. Dr. Laura Heacock, a breast radiologist, tested Grok with breast mammograms, ultrasounds, and MRIs, and found its performance lacking, with no single diagnosis correct. Meanwhile, Bradley Malin of Vanderbilt University highlighted that uploading medical scans to a social platform may expose sensitive health information.
Doctors who tested Grok, Elon Musk’s AI chatbot, reported some concerning errors. In one case, it missed a tuberculosis diagnosis, in another, it confused a broken clavicle with a shoulder injury. Grok AI misinterpreted a benign mammogram image in yet another instance. These mistakes have raised questions about Grok’s reliability for medical diagnoses.
