What you're renting

Compute die

NVIDIA B300 288GB — NVFP4 tensor cores, tuned for smallest frontier-capable footprint.

HBM3e memory

1,152 GB of HBM3e across the 4 GPUs.

NVLink 5 interconnect

NVLink 5 across the 4 GPUs — one memory domain.

Per-second metering

$48/hr → 0.0133/sec. Pause the deployment and the meter hits $0.

Scale-to-zero

Autoscale + region pins (GLOBAL / US / EU / APAC) on the control plane.

What fits here

Memory budget

1,152 GB of VRAM on this preset. Frontier MoE serving at full batch with KV-cache headroom (rule of thumb: about half a byte per parameter at NVFP4).

Typical loads

large MoE serving, high-QPS inference, batch evals at scale. Fine on: torch, JAX, raw CUDA, axolotl, vLLM, sglang, ComfyUI.

Billing math

$48/hr is $0.0133/sec while running and $0 while parked; park/wake freezes and restores state instead of paying for idle.

Sizing this preset

Best fit

1,152 GB across four B300 288 GB cards on NVLink 5 at $48/hr, $12 per GPU-hour — the catalog's smallest frontier-capable footprint. At NVFP4 a 1T-parameter checkpoint is ~500 GB of weights and leaves ~650 GB of the 1,152 GB pool; even at FP8 it is ~1 TB, most of the pool (rule of thumb).

Trade-off

b200-8x-fp4 is $80/hr: eight B200 180 GB cards, 1,440 GB total, $10 per GPU-hour. That is $32/hr more than this preset for twice the cards and 25% more VRAM, but 180 GB per card against 288 GB here — a job that needs 288 GB on one device stays on the B300 row.

Questions about this preset

What does the Minimal preset (4× NVIDIA B300 288GB) cost per hour?

$48/hr on runaii.cloud, metered per second: $0.0133/sec while the VM runs and $0 while parked. A month of 24/7 uptime would be about $35,040, and park/wake means busy-fraction pricing in practice.

Is the Minimal (4× NVIDIA B300 288GB) billed by the second?

Yes. Per-second metering with park/wake: idle freezes the VM state into a signed artifact and stops the meter the same second; the next request wakes it byte-exact

What fits on the Minimal (4 GPUs pooled)?

1,152 GB of VRAM. Frontier MoE serving at full batch with KV-cache headroom (rule of thumb: about half a byte per parameter at NVFP4).

How much VRAM does b300-4x-fp4 have?

1,152 GB — four 288 GB B300 HBM3e cards on NVLink 5 at $48/hr, $12 per GPU-hour.

What is the difference from b200-4x-fp4?

Same four-card shape, $8/hr more ($48 vs $40) and 1,152 GB instead of 720 GB: 288 GB per card against 180 GB, both at NVFP4.

Why is this the smallest frontier-capable preset?

It is the lowest-priced B300 shape in the catalog at $48/hr for four cards; the catalog's note for the row is exactly that phrase.
