B300 compute price

The B300 is a Blackwell Ultra datacenter GPU with 288 GB of memory. It is sized for very large models and long contexts. That memory is the reason it is priced well above the B200 and the H200.

If your model fits in less, a B300 is money spent on memory you do not use. Check the fit before you check the price.

On 12 Nov 2026, 10 providers listed an on-demand B300 price. The lowest was $6.60 per GPU-hour, the median $9.25 and the highest $17.80.

The B300 price table has every listing, with the smallest rental and a label for whether it can be started.

Most B300 prices are per GPU inside an 8-GPU machine. The bill is for all eight. On 12 Nov 2026, the lowest listed hourly total for such a machine was $52.80.

Many accounts cannot start one at all. The provider is sold out, or the card is held for customers who have spoken to sales, or a new account has no quota for it. The number on the page does not change in any of those cases. That is why each B300 row here carries a label and a date.

Decide first whether you need 288 GB on one card. If the model fits on a B200 or an H200, those are cheaper per hour and easier to find.

If you need a B300 for hours, not months, rent on demand and look for a small billing unit, so a short run is billed as a short run. If you need one for a month or longer, ask for a term price and compare its total with the on-demand cost of the hours you would really use.

Whichever you choose, try to start one before you plan around it. A B300 you can start today at a higher figure is worth more than a lower figure you cannot.
