NVIDIA B300

The B300 starts at $5.63 per GPU-hour, with a median of $7.89 across 15 available configurations. Actual pricing depends on the provider, region, and whether you rent on-demand, spot or reserved.

7 providers currently list the B300: Sesterce Cloud, Hyperstack, Scaleway, Vast.ai, Verda, Runpod and 1 more. Compare their hourly pricing, regions and machine specs in the table above.

The B300 comes with 288 GB of VRAM, which determines the largest models and batch sizes it can hold in memory for training and inference.

With 288 GB of VRAM, a single B300 can serve models such as DeepSeek V4 Flash, Solar Open2 250B, Qwen3 235B-A22B, Laguna-S 2.1. The table above lists the estimated VRAM for each model at 16-bit, 8-bit and 4-bit precision, including the multi-GPU configurations needed for larger models.

The largest models we track that fit across several B300 cards are Kimi K3 on 8 GPUs at 4-bit, DeepSeek V4 Pro on 4 GPUs at 4-bit, Kimi K2.5 on 4 GPUs at 4-bit. A multi-GPU configuration means you rent and pay for every card for the whole run, and splitting a model across cards costs throughput as well: the GPUs exchange activations on every token, so performance depends on how fast they are wired together. We do not track interconnect, so check the provider's node specification. The table above gives the smallest configuration for each model at 16-bit, 8-bit and 4-bit precision.

The lowest on-demand price we currently track for the B300 is $5.63 per GPU-hour at Vast.ai. Because providers update pricing and availability frequently, check the live table above before you launch.
