Inputs (17)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | The prompt for image editing. | |
| num_images | INT | 11–4 | The number of images to generate. |
| seed | INT | -1-1–2147483647 | The seed for the random number generator. -1 leaves it to the model. |
| aspect_ratio | COMBO | auto | The aspect ratio of the generated image. |
| output_format | COMBO | png | The format of the generated image. |
| safety_tolerance | COMBO | 4 | The safety tolerance level for content moderation. 1 is the most strict (blocks most content), 6 is the least strict. |
| image_1 | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| limit_generations | BOOLEAN | true | Experimental parameter to limit the number of generations from each round of prompting to 1. Set to `True` to to disregard any instructions in the prompt regarding the number of images to generate. |
| image_2opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_3opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_4opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_5opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_6opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| 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. |
