CrankGPT is a human-powered, fully local and private AI solution that uses a hand-crank or pedal-powered model to generate tokens, allowing users to produce their own AI without relying on cloud services or giving away their data. The device is designed to be used for everyday home use, with more capable models available for power users and small companies. The idea behind CrankGPT is to provide a private and sustainable alternative to traditional AI solutions. The device is also seen as a way to promote physical exercise and reduce reliance on fossil fuels.
