B300 GPU pricing: rental cost per hour across cloud providers
The cheapest B300 GPU rental tracked by ByteCosts is about $6.60 per GPU-hour on-demand at Massed Compute (b300-sxm6-x8 in published), or roughly $3.75 per GPU-hour on spot. B300 is available from 8 of the providers in the catalog across 19 regions. Rates are cloud rental list prices per GPU-hour (instance price divided by GPU count), not card MSRP, and exclude committed-use discounts. Spot capacity is cheaper but interruptible, so size on-demand for steady jobs and use spot for checkpointed work.

How to choose where to rent B300
The lowest per-GPU-hour rate is a starting point, not the decision. B300 cost in practice depends on utilization (an idle reserved GPU bills the full rate), whether your job tolerates spot interruption, and region and egress fees for moving weights or datasets.
Pick the cheapest provider that has capacity in a region near your data, can keep the GPU busy, and offers spot if your workload is checkpointed. A slightly higher headline rate in the right region often beats the cheapest row once egress and idle time are counted.
