The Economics of Open-Weight Inference

GPU cloud price comparison

This table compares current cloud GPU rental prices at the model level using Ornn Compute Price Index settlements. These are executed-market benchmarks, not provider quotes. Daily cost is hourly times 24. Monthly cost uses a 30-day month (hourly times 24 times 30). The page is not a provider availability table or an executable quote.

OCPI versus seller-posted cloud rates

Seller-posted cloud rates are list prices or availability quotes from a specific operator. OCPI values are volume-weighted, winsorized averages of executed rental transactions across the neocloud market. They settle once per trading day and are not a bid, offer, or inventory snapshot for any one seller.
