By provider shows one card per company, placed where its best offer ranked. By configuration lists every offer.
What you can rent comes first: in stock, then waitlist, then not reported, then out of stock. Priced offers rank ahead of quote-only, and on-demand ahead of other billing types.
Within a group, five factors set the order:
We match the provider, its country, GPU model, form factor, billing type, availability and instance name. Matching is partial and case-insensitive. Everyday words work too, so "interruptible" finds spot and "sold out" finds out of stock.
No providers match .
Heads up: A provider's own page may quote a different figure, for example on tax, region or a promotion. A monthly-only plan shows a derived hourly rate. Verify before provisioning. More on how we price.
One RTX 4090 has 24 GB of VRAM. In practice, that's enough memory for roughly 28B parameters at 4-bit or 6B at 16-bit, assuming a 32K context. Below are some open-weight LLMs, with the estimated memory and GPUs each one needs.

Estimates based on the median on-demand rate. Memory is weights plus FP8 KV cache at 32K context per request (FP16/BF16 in the 16-bit column). GPU counts assume 90% of advertised VRAM is usable. No guarantee of runtime support, usable performance, or that a matching quantized build exists. Pricing methodology.

As of October 4, 2026, the median on-demand price is $0.45 per GPU per hour across 14 providers with a priced on-demand config.
| Billing type | Configs | Median /GPU/hr | Cheapest |
|---|---|---|---|
On-demand | 112 | $0.45 | $0.33 (in stock, Salad) |
Reserved | 96 | $0.52 | $0.28 (3 mo, in stock, Vast.ai) |
Spot | 62 | $0.34 | $0.16 (in stock, Salad) |
1 provider also quotes the RTX 4090 on a custom contract, priced per deal.
At 720 hours per month, one RTX 4090 costs an estimated $324 at the median on-demand price. Cheapest verified in stock: $238 per month on-demand, $202 reserved (3 mo), $115 spot.
GetDeploying currently tracks RTX 4090 configs from 20 providers. The cheapest verified in-stock on-demand configs come from Salad, Vast.ai, GPU.ai and Runpod. See the full price comparison above for every provider and config.
As of October 4, 2026, the median on-demand price has been flat over the past 90 days, at about $0.45 per GPU per hour, though it is about 14% below where it was a year ago.
One RTX 4090 runs models up to roughly 28B parameters at 4-bit quantization or 6B at 16-bit, assuming a 32K context. Larger models run across multiple GPUs: the model table above shows the estimated memory and GPU count for popular open-weight LLMs.
24GB GDDR6X with Ada Lovelace FP8 Tensor Cores. Highest-performing consumer GPU of the Ada generation. Can run 13B parameter models at FP16 or 30B+ quantized. Popular for AI research and Stable Diffusion.
Consumer GeForce GPU. No ECC memory. 24GB VRAM is limiting for larger LLMs. Subject to Nvidia's consumer EULA, which may restrict data center use. For production inference, consider the L40S.
