xAI and OpenAI use modified jet engines to power AI data centers

xAI installs 8 modified jet engine turbines in its Memphis data center, while OpenAI adopts gas turbines in its Abilene Stargate project, both transformed by ProEnergy from General Electric engines. The modified engines are deployed quickly, allowing the data center to operate within 24 months, but their efficiency is lower than traditional gas power plant turbines, and they are expected to be only a short-term solution.
