Cheapest cloud GPU is a search people type when they have already been surprised by a bill. The honest answer is the offer that holds the model and stops when the work stops. A Blackwell GPU rental is only cheapest if the job actually needs that memory.
OpenSEO has two related saved terms besides gpu rental prices: blackwell gpu rental and b200 gpu rental price. Both are buyer queries. This note answers them with the November 5, 2026 NovaPod book, then says which of the other nine sites are even in the same product.
A cheapest cloud GPU ladder
Start at 24 GB. The RTX 4090 floor that day was $0.09 an hour, median $0.35, 419 offers. A 7B or 14B chat model, a small LoRA, and plenty of ComfyUI batches fit. If they fit, every more expensive card is a more expensive card.
Thirty-two gigabytes was the RTX 5090, from $0.26, median $0.46, 648 offers. That is the step when 24 GB spills and you are not ready for a datacenter card.
Eighty gigabytes was the H100 SXM, from $1.21, median $1.68, 65 offers. One hundred forty-one gigabytes was the H200, from $2.76. One hundred ninety-two gigabytes was the B200, from $4.38. I left the B200 unrented. I had not failed at 141 GB.
| If you need | Card | Floor that day |
|---|---|---|
| 24 GB | RTX 4090 | $0.09/hr |
| 32 GB | RTX 5090 | $0.26/hr |
| 80 GB | H100 SXM | $1.21/hr |
| 141 GB | H200 | $2.76/hr |
| 192 GB | B200 | $4.38/hr |
Blackwell GPU rental is a memory purchase
B200 is Blackwell. The B200 rental price on this book started at $4.38 an hour for 192 GB. Against the H200 floor of $2.76 for 141 GB, you pay the gap for the extra memory and the architecture, not for a cheaper hour.
A Blackwell GPU rental is the wrong search if the error on screen is a 24 GB card. It is the right search if an H200 already ran out of memory, or the job is specified as B200. The GPU list is where that card's current ask lives. This paragraph will go stale. The list will not.
Which of the ten can even be the cheap option
NovaPod, Vast.ai, RunPod, and TensorDock are the spot books. A short job should be priced there, per second, on the day. Spheron is in that set if you are already paying in crypto and want another catalog.
Lambda and Paperspace can be cheap for a notebook-shaped job on a card your company already has. They are a poor place to hunt a five-minute floor. CoreWeave, Crusoe, and a reserved Lambda cluster win when the rental is long enough that a contract beats spot. Genesis Cloud enters when the region is the constraint and the hour is not.
The product advantage on NovaPod for the cheap end of this ladder is the same balance for a 4090 test and a later H100. You do not open a second account to step up memory. You stop the small pod first.
Questions about the cheapest cloud GPU
Is the B200 the cheapest Blackwell rental? It was the B200 floor I saw on NovaPod on November 5, at $4.38 an hour. It was not the cheapest GPU. The 4090 was.
Should I trust a $0.09 RTX 4090? It was a floor, with a $0.35 median behind it. Read the offer, then stop it when the batch ends.
Where is the live B200 price? On the GPU list and the marketplace, not in a dated paragraph.
