Start with a Hugging Face model, GPU, and real traffic shape. The result keeps fit, utilization, idle capacity, provider dates, and every caveat visible.

Llama-3.1-8B-Instruct on NVIDIA L4 24 GB

1 GPU, FP16, 50,000 requests/day. 500 input and 500 output tokens per request.

Estimated memory fit

Fits in memory, cost withheld.

No measured aggregate serving capacity matches this configuration. Memory fit and dated hourly rates remain available; monthly rent, replica counts, and API comparisons are withheld.

Memory required: 19.7 GB
Usable GPU memory: 21.6 GB

Provider price spread, NVIDIA L4 24 GB

Dated GPU-hour rental prices for this hardware. They are not monthly serving totals because throughput evidence is missing.

Each bar compares the labelled value on the same scale.

What this chart means

These are GPU-hour rental prices only. A monthly serving total requires throughput evidence and remains absent.

Caveats

Served context is 8192 tokens. It is a serving-capacity decision and is not inferred from average input or output tokens.
KV cache uses the exact transformer-shape formula with 32 layers, 8 KV heads, and head dimension 128.
Runtime overhead adds 2.6 GB to the total memory requirement. This approximate 15% policy allowance covers CUDA context, activations, and vLLM overhead. Deployment-time profiling, including CUDA graph capture and allocator behavior, can differ.
Single-stream physics ceiling, not batched serving capacity. Batching changes aggregate throughput, so this concurrency-1 model cannot establish a minimum replica count or monthly rent. A measured serving benchmark matching the workload is required.
Compute prefill ceiling: 7,534 tokens/sec. Bandwidth decode ceiling: 18 tokens/sec.
the workload settings has no GPU provider selector. The calculation uses the lowest supplied on-demand rate for L4: RunPod, Secure Cloud at $0.39/GPU-hour.
The Hugging Face repository is gated. Running the generated command requires authorized access to the model weights.

Share this calculation

Embed code appears only when the calculator can publish a sourced cost for a fitting configuration.

Badge unavailable for this configuration

The calculator does not have a complete throughput source for this workload, so it withheld the cost and does not generate embed code.
