CoreWeave vs Vast.ai
CoreWeave
CoreWeave is a specialized GPU cloud operator with massive fleets of HGX H100, H200, GB200 NVL72, and B200 systems interconnected with high-speed InfiniBand networking. Purpose-built for large-scale AI training and inference at enterprise-grade reliability, it has become a preferred alternative to hyperscalers for GPU-intensive workloads.
Vast.ai
Vast.ai is a decentralized GPU marketplace where host operators list idle accelerators at market-driven prices - often the lowest spot rates anywhere. The trade-off is variable reliability, no compliance certs, and community-grade support; ideal for cost-sensitive experimentation, fine-tuning, and batch inference where occasional interruption is acceptable.
