SpaceX has shown investors a prototype AI device similar in form to a smartphone, the Wall Street Journal reported on Tuesday. The company is believed to have unveiled the device to investors and other stakeholders ahead of a listing. The device is at an early stage and its design could change. Elon Musk denied the report as “completely fake news.” The prototype was described as thinner than an iPhone.

SpaceX is preparing to launch a new Starlink Mini satellite internet antenna with a built-in battery that can operate without a separate power connection. Clues pointing to a battery-integrated model were found in analysis of Starlink’s latest firmware source code. The code includes lines to check battery status and defines three independent power states, implying support for wired power, an internal battery, or both. This could address issues seen with third-party battery products.
