Navigation Fund, a nonprofit founded by Ripple co-founder Jed McCaleb, has launched Voltage Park, a cloud service that offers access to 24,000 NVIDIA GPUs for machine learning modeling. The hardware is worth $500 million and is available on an hourly, monthly or long-term basis. Voltage Park is currently auctioning off contracts with lengths of one-to-three months on 1,560 GPUs. The Navigation Fund was founded in 2023 and plans to expand its programs in early 2024.
