What it costs to run — $0 markup

On your own machine — $0. Runs free if you have about 4.0 GB of VRAM (~2-4GB; extremely high throughput (RTFx ~3000+)), via NVIDIA NeMo.
Rent a GPU — from $0.26/hr. Fits RTX 3090 24GB at the direct vendor price ($0 markup) — pay only for the minutes you generate.
Download the weights — free. Open weights at nvidia/parakeet-tdt-0.6b-v2.

Note: generative-media models are billed per image / per second / per minute on hosted services — not per token. Running locally or on your own rented GPU is usually far cheaper and keeps your data on your machine.
