What it costs to run — $0 markup

• On your own machine — $0. Runs free if you have about 13 GB of VRAM (fp8 ~13GB, 4-bit ~6.5GB; fp16 ~26GB; a 2B distilled variant runs near real-time), via ComfyUI / Diffusers.
• 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 Lightricks/LTX-Video.

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.
