The Economics of Open-Weight Inference
Open-weight models are cheaper only at several sampled common score thresholds, not at every threshold. That A100/H100 sparse result combines different third-party serving setups. The published five-year A100 mark retains 80.2% of the one-month term price, versus 43.7% to 59.8% for Hopper and 53.8% for Blackwell families.
