They are different kinds of provider — Massed Compute is a neocloud, Vast.ai a marketplace — which is most of why the prices differ.
Where do these prices come from?
Massed Compute: Public pricing page, parsed. Per-GPU price is the listed per-GPU rate, or the node price divided by GPU count. Prices near reserved, committed or contract terms are discarded; anything outside a plausible range for the GPU is discarded. Vast.ai: Public offer search, verified and rentable hosts only. Each offer is one observation; on-demand rate, not interruptible bids. Both are read every six hours; nothing is estimated.
