Inputs (8)
| Name | Type | Default | Description |
|---|---|---|---|
| image | IMAGE | The URL of the input image to erase content from. | |
| mask | MASK | The URL of a black/white mask image where white (255) marks pixels to erase and black (0) marks pixels to keep. Needs to match the dimensions of the input image. | |
| dilate_pixels | INT | 100–100 | Number of pixels to expand the mask edges by. Higher values produce cleaner erase results around the masked region. |
| output_format | COMBO | jpeg | The format of the generated image. |
| max_cost_usdopt | FLOAT | 20.00–100000 | Safety cap. If the estimated cost of this run is above this many US dollars the node stops BEFORE sending anything to fal. 0 = no cap. |
| reuse_identical_runopt | BOOLEAN | true | If these exact inputs (the settings AND the same pictures/clips/audio) were already paid for and the files are still in output/fal, return them instead of paying again - also after a ComfyUI restart. Turn off for a fresh take with the same settings. |
| extra_jsonopt | STRING | Advanced: a JSON object merged into the request last, for any fal field this node has no box for. Example: {"seed": 7}. Leave empty normally. | |
| max_concurrentopt | INT | 11–32 | How many paid fal calls may run at the same time in one run, across every fal node. 1 (default) = one after another. This node starts its paid part only while fewer than this many fal calls are running. Once any fal node fails, the ones still waiting are not started, so nothing more is billed. |
