How the B300 price is built
- Realtime = median of live on-demand asks on Vast.ai, blended 60/40 with the published on-demand median of Lambda, RunPod, Nebius, GMI and CoreWeave.
- Spot = median of live minimum bids for interruptible capacity.
- Each model has a floor and a ceiling; a thin or noisy order book can't push the index outside it.
- Refreshed hourly; the 30d column is the trend of realtime prints.
