What you're renting

Compute die

NVIDIA B200 180GB — NVFP4 tensor cores, tuned for ≤70b dense models, evals.

HBM3e memory

720 GB of HBM3e across the 4 GPUs.

NVLink 5 interconnect

NVLink 5 across the 4 GPUs — one memory domain.

Per-second metering

$40/hr → 0.0111/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

720 GB of VRAM on this preset. 70B+ dense checkpoints fit with room for KV cache (rule of thumb: about half a byte per parameter at NVFP4).

Typical loads

multi-tenant inference, parallel eval harnesses, 70B+ dense serving. Fine on: torch, JAX, raw CUDA, axolotl, vLLM, sglang, ComfyUI.

Billing math

$40/hr is $0.0111/sec while running and $0 while parked; park/wake freezes and restores state instead of paying for idle.

Sizing this preset

Best fit

720 GB across four B200 180 GB cards on NVLink 5 at $40/hr, $10 per GPU-hour. The catalog lists this row at NVFP4 and sizes it for ≤70B dense models; at FP8 weights a 70B checkpoint is ~70 GB, leaving ~650 GB of the 720 GB pool for KV cache and batch concurrency (rule of thumb).

Trade-off

b300-4x-fp4 is $48/hr — $8/hr more — for the same four-card shape with B300 288 GB cards, 1,152 GB total instead of 720 GB, still at NVFP4. Per GPU that is $12/hr against $10/hr, so the step up buys 60% more VRAM per card.

Questions about this preset

What does the Efficient preset (4× NVIDIA B200 180GB) cost per hour?

$40/hr on runaii.cloud, metered per second: $0.0111/sec while the VM runs and $0 while parked. A month of 24/7 uptime would be about $29,200, and park/wake means busy-fraction pricing in practice.

Is the Efficient (4× NVIDIA B200 180GB) 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 Efficient (4 GPUs pooled)?

720 GB of VRAM. 70B+ dense checkpoints fit with room for KV cache (rule of thumb: about half a byte per parameter at NVFP4).

What is the price per GPU on b200-4x-fp4?

$10/hr — $40/hr for four B200 180 GB cards, the lowest B200 hourly in the catalog (the 8× B200 row is $80/hr).

What does the 720 GB pool buy beyond the weights?

A 70B checkpoint at FP8 is ~70 GB of weights, so most of the 720 GB is KV cache and batch headroom — the catalog note targets ≤70B dense models here (rule of thumb).

Is there a 4-card B200 FP8 preset?

No — the catalog lists b200-4x-fp4 at NVFP4. The catalog's 8-card FP8 row is b300-8x-fp8 (8× B300 288GB, $96/hr); there is no 4-card B200 FP8 preset.
