Run on Modal

The ComfyUI workers also run on Modal, another serverless GPU service billed by the second, from modal_app.py in each repo. It builds the same Dockerfile and answers the same requests as on RunPod (/run, /status/<id>), so a client that calls RunPod endpoints needs only the other address and key. The Models page shows which workers have it.

On your computer, with Python 3.10 or newer, in a copy of your repo (git clone it, with your Dockerfile lines filled in):

Terminal window
pip install modal
modal setup                                                   # opens a page to sign in to Modal
modal secret create cobaltpear-key CP_KEY=<a long password you make up>
modal deploy modal_app.py                                     # builds, then prints the worker's address
  • The address ending in -api….modal.run is your endpoint; send Authorization: Bearer <that password> with each request.
  • GPU: the GPU line at the top of modal_app.py — set to the smallest one that fits the model. A worker turns off 60 s after its last picture.
  • Modal needs a payment method on your account to use GPUs. Its prices: modal.com/pricing.
  • Updates: run modal deploy modal_app.py again.
