Vast.ai runs a marketplace that connects GPU owners with users who need high-performance computing for AI and machine learning. Users browse available hardware, compare performance using the DLPerf scoring function, and rent compute through interruptible instances and spot auctions to save money. The platform aggregates offerings from individuals, data centers, and large providers, enabling a diverse, competitive marketplace while prioritizing security and regulatory compliance. This approach lets customers choose hardware that matches their needs and budget, rather than sticking to traditional cloud providers. Vast.ai’s goal is to make AI development more accessible and to improve the utilization of existing computing resources, contributing to cost efficiency and sustainability in tech.
