  --highvram            By default models will be unloaded to CPU memory after being used. This option keeps them

  --disable-smart-memory
                        Force ComfyUI to agressively offload to regular ram instead of keeping models in vram when
                        it can.
  --deterministic       Make pytorch use slower deterministic algorithms when it can. Note that this might not
                        make images deterministic in all cases.
  --fast                Enable some untested and potentially quality deteriorating optimizations.
  --dont-print-server   Don't print server output.
  --quick-test-for-ci   Quick test for CI.
  --windows-standalone-build
                        Windows standalone build: Enable convenient things that most people using the standalone
                        windows build will probably enjoy (like auto opening the page on startup).
  --disable-metadata    Disable saving prompt metadata in files.
  --disable-all-custom-nodes
                        Disable loading all custom nodes.
  --multi-user          Enables per-user storage.
  --verbose             Enables more debug prints.
  --front-end-version FRONT_END_VERSION
                        Specifies the version of the frontend to be used. This command needs internet connectivity
                        to query and download available frontend implementations from GitHub releases. The version
                        string should be in the format of: [repoOwner]/[repoName]@[version] where version is one
                        of: "latest" or a valid version number (e.g. "1.0.0")
  --front-end-root FRONT_END_ROOT
                        The local filesystem path to the directory where the frontend is located. Overrides
                        --front-end-version.
