USD per GPU-hour, taxes excluded, rounded to the cent. The AWS price covers the whole instance (US East). Vultr's figure comes from its public plans API, which did not confirm availability. 'None documented' means no ID step in the official pages we read, not a promise that a provider never asks.

## L40S vs A100: which is the better deal per hour?

For FP8 inference and image generation, the L40S. According to GPUwithCrypto's price check of 29 October 2026, a median on-demand L40S costs 25% less than a median A100 80GB ($1.67 against $2.23). It also has FP8 Tensor Cores, which the A100 lacks.

The A100 keeps two advantages: 80 GB of memory against 48 GB, and 2,039 GB/s of bandwidth on the SXM version against 864 GB/s. A job that needs more than 48 GB, such as a 70B model in 4-bit with a 32K-token context (about 53 GB), needs the A100. On GPUwithCrypto the two cost $0.82/hour and $0.92/hour. The [L40S vs A100 comparison](https://gpuwithcrypto.com/compare/l40s-vs-a100/ "L40S vs A100 for inference and fine-tuning: which should I rent?") goes further.

## Why are marketplace and spot L40S cheaper than ours?

Because a host sets the marketplace price, and the provider can stop a spot GPU. On 29 October 2026, Vast.ai's public price feed listed 61 rentable L40S offers, from $0.33 with a median of $0.73. Nebius listed preemptible L40S from $0.74, and RunPod's community-hosted Community Cloud charged $0.79.

Those three prices were below our $0.82 that day. They fit batch jobs that can restart. For a server that must stay up, compare on-demand prices: ours is 51% below the on-demand median. Instances are on-demand, not spot: nobody can take your GPU back while your balance covers it, and the instance runs until you stop it.

## How much does an L40S cost per day, week or month?

Our price for one GPU next to the lowest and the median self-serve on-demand price of 29 October 2026, for the same number of hours.

| Period | GPU-hours | GPUwithCrypto | Lowest elsewhere (Massed Compute) | Median elsewhere |
| --- | --- | --- | --- | --- |
| 1 hour | 1 | **$0.82** | $0.97 | $1.67 |
| 1 day | 24 | **$19.68** | $23.28 | $40.10 |
| 1 week | 168 | **$137.76** | $162.96 | $280.73 |
| 30 days | 720 | **$590.40** | $698.40 | $1,203.12 |

*Prices checked on October 29, 2026.*

The median is $1.671 per GPU-hour before rounding. Our day, week and month match the 24, 168 and 720 GPU-hour blocks.

## What are the L40S's specs?

## What fits on one L40S?

Memory needed for common open models, using weights × 1.2 for inference (EleutherAI's rule of thumb) and weights plus adapters for LoRA. The [VRAM guide](https://gpuwithcrypto.com/how-much-vram-do-i-need/ "How much VRAM do I need to run or fine-tune an LLM?") has the formulas.

| Model and job | Memory needed | One L40S 48GB? |
| --- | --- | --- |
| Llama 3.1 8B inference, BF16 | ≈ 19.2 GB | Yes |
| Llama 3.1 8B LoRA fine-tune | ≈ 19.2 GB | Yes |
| Llama 3.1 70B inference, 4-bit | ≈ 42 GB | Yes |
| Qwen2.5 72B inference, 4-bit | ≈ 43.6 GB | Yes |
| Llama 3.1 70B QLoRA fine-tune | ≈ 52.5 GB | Borderline: the QLoRA authors fine-tuned a 65B model on one 48 GB GPU |
| FLUX.1 [dev] transformer, BF16 weights | 24 GB, plus text encoders and VAE | Yes |
| FLUX.1 [dev] LoRA training | ≈ 28.8 GB | Yes |
| SDXL 1.0 base, FP16 weights | 7 GB | Yes |
| Llama 3.1 70B inference, FP8 | ≈ 84 GB | No: 2× L40S |
| Llama 3.1 8B full fine-tune | ≈ 128 to 144 GB before activations | No |

## What does an L40S cost on GPUwithCrypto?

$0.82/hour, at least 15% under its named on-demand reference: Massed Compute at $0.97, read on 29 October 2026. We do not claim to be the cheapest for every GPU; spot and marketplace offers (Vast.ai) can be lower. Instances are billed per minute at the hourly rate while they run, from the GPU-hours you bought for that GPU. Stopping an instance stops the charge at once. GPU-hours are sold in blocks of 10, 24, 168 or 720 hours for one GPU model, at the same hourly rate; instances of that GPU draw from them per minute, and unused hours never expire.

| Plan | Quantity | Price | Price per unit |
| --- | --- | --- | --- |
| Try | 10 GPU-hours | $8.20 | $0.82/hour |
| Day | 24 GPU-hours | $19.68 | $0.82/hour |
| Week | 168 GPU-hours | $137.76 | $0.82/hour |
| Month | 720 GPU-hours | $590.40 | $0.82/hour |

In every plan: Whole GPUs, never shared · Root SSH, CUDA and PyTorch ready · Billed per minute · Unused hours never expire

**Before you pay**

- Minimum top-up $1. Top up once in crypto, then buy any plan from your balance.
- Credit on your balance does not expire and buys blocks of GPU-hours for any GPU. When a top-up is only made to reach the minimum, the unspent part comes back on request within 30 days of payment, in USDT or USDC. The rest of a balance is not paid out unless the law requires it.
- Credited once your payment is checked on the blockchain. Typical network confirmation time: BTC ≈ 20 min · USDT TRC-20 ≈ 1 min · USDT ERC-20 ≈ 5 min · USDC ERC-20 ≈ 5 min · ETH ≈ 5 min · SOL ≈ 1 min · LTC ≈ 15 min · XMR ≈ 20 min

## L40S price questions

### What is the cheapest L40S cloud?

On 29 October 2026 the lowest self-serve on-demand L40S price we found was $0.97 at Massed Compute, and GPUwithCrypto charges $0.82. Vast.ai's public price feed showed marketplace offers from $0.33, set by independent hosts.

### How much does an L40S cost per month?

720 GPU-hours cost $590.40 on GPUwithCrypto. At the median on-demand price of 29 October 2026 the same month cost $1,203.12, and $698.40 at the lowest.

### Can an L40S run a 70B model?

Yes in 4-bit: Llama 3.1 70B needs about 42 GB and fits in 48 GB. In FP8 it needs about 84 GB, so two L40S. The L40S has no NVLink, so multi-GPU runs go over PCIe.

### Is the L40S good for ComfyUI and Flux?

It has the memory for it. FLUX.1 [dev] weights take 24 GB in BF16, and LoRA training needs about 28.8 GB, both inside 48 GB. See the [best GPU for ComfyUI and Flux](https://gpuwithcrypto.com/best-gpu-for/comfyui-flux/ "What is the best cloud GPU for ComfyUI, Stable Diffusion and Flux?").

### Can I rent an L40S with crypto?

Yes. GPUwithCrypto takes BTC, USDT, USDC, ETH, SOL, LTC, XMR with no ID and no card. Of the 11 self-serve L40S providers we checked, 5 accept crypto: Massed Compute, DigitalOcean, Vultr, Spheron and RunPod. RunPod asks for KYC before the first crypto payment.
