NVIDIA B300 nodes, reserved from $4.23 per GPU-hour

As of October 2026, a dedicated 8-GPU NVIDIA B300 HGX node from Avian costs $4.95 per GPU-hour on a 12-month term ($28,908 per node per month) and $4.23 per GPU-hour on a 36-month term. You pay once for the whole term, the rate is locked from the day you reserve, and the node is live in under 48 hours.

What's in a B300 node

A complete HGX system, single-tenant: all 8 GPUs and the full NVLink domain are yours for the whole term.

What one B300 node can run

With 2,304 GB of GPU memory in a single NVLink domain, one node holds models that would otherwise need to be split across machines:

  • A model of about 1 trillion parameters in FP8 (around 1,000 GB of weights), with roughly 1,300 GB left for KV cache and long contexts.
  • A 400B-class dense model in BF16 (around 800 GB), or several mid-size models side by side.
  • High-concurrency serving of 100B–200B models, where the extra memory goes to KV cache instead of more nodes.

Not sure your model fits? Work it out with the GPU memory calculator.

B300 or B200?

The B300 has 288 GB per GPU against the B200's 180 GB and 15 PFLOPS of dense FP4 against 9. The B200 is the cheaper node when your model fits comfortably in 1,440 GB.

B300 reservation FAQ

12 months is the shortest term on sale right now (1 month, 3 months, 6 months terms are sold out). Terms run up to 36 months, and the longer the term, the lower the rate: $4.23 per GPU-hour on a 36-month term.

One payment for the whole term, with no hourly metering. Send a request and we'll confirm availability and invoice you (NET-30 or PO on 12-month and longer terms), or pay for a single node online by PayPal or card.

Standard reservations are provisioned in under 48 hours from payment. Multi-node clusters with fabric interconnects are typically ready within 5 business days.

Yes. Online payment covers one node; for two or more, send a request with the node count and sales will quote volume pricing, with InfiniBand or RoCE between nodes.

No. Each node is single-tenant: all 8 GPUs and the full NVLink domain are reserved for you for the whole term, and the rate never changes during it.
