Where to run it

If it fits your card, run it at home: an RTX 4090 draws about $0.09 of power an hour. If not, an RTX 4090 rents from $0.33 an hour, Comfy Cloud bills $4.54 an hour of generation on a 96 GB card, and RunPod sells a 720p Wan 2.2 clip for $0.30. Prices read 9 to 19 October 2026.

What you pay for

Your own GPU
Power only, a little while idle
Comfy Cloud
Only while it generates
A GPU by the hour
The whole session, idle included
A per-clip API
Each clip it makes
An illustration: a 2-hour session in which the GPU generates 25% of the time, the example the ComfyUI cloud guide prices, billed four ways. The four run on different cards at different prices, so it shows what you pay for, not how much.

Which one, when

The short answer

Check your own card first; pay for what it cannot do.

It fits your card
Run it at home No meter, and your files stay with you. A smaller file often closes a gap of a few GB.
A ComfyUI workflow whose nodes Comfy Cloud has
Comfy Cloud It bills only while a workflow runs, on a 96 GB card. You cannot add custom nodes yourself.
Custom nodes, your own models, long sessions
A GPU by the hour Any setup you like. You set it up, and you pay while the machine is on.
One model, called from your code
An API The simplest bill per image or clip, on their model and settings rather than your workflow.
An open LLM to chat with
Your card, or Ollama Cloud Ollama Cloud sells monthly credits for the open models it hosts; the guide says which of them fit a machine at home.
